The value of this property should be a string representing a path + to another object or a custom binding instanced created using Binding helpers + (see "One Way Bindings"): + + ``` + valueBinding: "MyApp.someController.title" + ``` + + This will create a binding from `MyApp.someController.title` to the `value` + property of your object instance automatically. Now the two values will be + kept in sync. + + ## One Way Bindings + + One especially useful binding customization you can use is the `oneWay()` + helper. This helper tells Ember that you are only interested in + receiving changes on the object you are binding from. For example, if you + are binding to a preference and you want to be notified if the preference + has changed, but your object will not be changing the preference itself, you + could do: + + ``` + bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") + ``` + + This way if the value of `MyApp.preferencesController.bigTitles` changes the + `bigTitles` property of your object will change also. However, if you + change the value of your `bigTitles` property, it will not update the + `preferencesController`. + + One way bindings are almost twice as fast to setup and twice as fast to + execute because the binding only has to worry about changes to one side. + + You should consider using one way bindings anytime you have an object that + may be created frequently and you do not intend to change a property; only + to monitor it for changes (such as in the example above). + + ## Adding Bindings Manually + + All of the examples above show you how to configure a custom binding, but the + result of these customizations will be a binding template, not a fully active + Binding instance. The binding will actually become active only when you + instantiate the object the binding belongs to. It is useful however, to + understand what actually happens when the binding is activated. + + For a binding to function it must have at least a `from` property and a `to` + property. The `from` property path points to the object/key that you want to + bind from while the `to` path points to the object/key you want to bind to. + + When you define a custom binding, you are usually describing the property + you want to bind from (such as `MyApp.someController.value` in the examples + above). When your object is created, it will automatically assign the value + you want to bind `to` based on the name of your binding key. In the + examples above, during init, Ember objects will effectively call + something like this on your binding: + + ```javascript + binding = Ember.Binding.from(this.valueBinding).to("value"); + ``` + + This creates a new binding instance based on the template you provide, and + sets the to path to the `value` property of the new object. Now that the + binding is fully configured with a `from` and a `to`, it simply needs to be + connected to become active. This is done through the `connect()` method: + + ```javascript + binding.connect(this); + ``` + + Note that when you connect a binding you pass the object you want it to be + connected to. This object will be used as the root for both the from and + to side of the binding when inspecting relative paths. This allows the + binding to be automatically inherited by subclassed objects as well. + + Now that the binding is connected, it will observe both the from and to side + and relay changes. + + If you ever needed to do so (you almost never will, but it is useful to + understand this anyway), you could manually create an active binding by + using the `Ember.bind()` helper method. (This is the same method used by + to setup your bindings on objects): + + ```javascript + Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); + ``` + + Both of these code fragments have the same effect as doing the most friendly + form of binding creation like so: + + ```javascript + MyApp.anotherObject = Ember.Object.create({ + valueBinding: "MyApp.someController.value", + + // OTHER CODE FOR THIS OBJECT... + }); + ``` + + Ember's built in binding creation method makes it easy to automatically + create bindings for you.

The last argument is + required to be an options object. The options object can have the + following three properties. + + `initialize` - An optional initialize function. Typically this will be used + to set up state on the instanceMeta object. + + `removedItem` - A function that is called each time an element is + removed from the array. + + `addedItem` - A function that is called each time an element is + added to the array. + + + The `initialize` function has the following signature: + + ```javascript + function (array, changeMeta, instanceMeta) + ``` + + `array` - The initial value of the arrayComputed, an empty array. + + `changeMeta` - An object which contains meta information about the + computed. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + + The `removedItem` and `addedItem` functions both have the following signature: + + ```javascript + function (accumulatedValue, item, changeMeta, instanceMeta) + ``` + + `accumulatedValue` - The value returned from the last time + `removedItem` or `addedItem` was called or an empty array. + + `item` - the element added or removed from the array + + `changeMeta` - An object which contains meta information about the + change. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + - `index` the index of the added or removed item + - `item` the added or removed item: this is exactly the same as + the second arg + - `arrayChanged` the array that triggered the change. Can be + useful when depending on multiple arrays. + + For property changes triggered on an item property change (when + depKey is something like `someArray.@each.someProperty`), + `changeMeta` will also contain the following property: + + - `previousValues` an object whose keys are the properties that changed on + the item, and whose values are the item's previous values. + + `previousValues` is important Ember coalesces item property changes via + Ember.run.once. This means that by the time removedItem gets called, item has + the new values, but you may need the previous value (eg for sorting & + filtering). + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + The `removedItem` and `addedItem` functions should return the accumulated + value.

The last argument is + required to be an options object. The options object can have the + following four properties: + + `initialValue` - A value or function that will be used as the initial + value for the computed. If this property is a function the result of calling + the function will be used as the initial value. This property is required. + + `initialize` - An optional initialize function. Typically this will be used + to set up state on the instanceMeta object. + + `removedItem` - A function that is called each time an element is removed + from the array. + + `addedItem` - A function that is called each time an element is added to + the array. + + + The `initialize` function has the following signature: + + ```javascript + function (initialValue, changeMeta, instanceMeta) + ``` + + `initialValue` - The value of the `initialValue` property from the + options object. + + `changeMeta` - An object which contains meta information about the + computed. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + + The `removedItem` and `addedItem` functions both have the following signature: + + ```javascript + function (accumulatedValue, item, changeMeta, instanceMeta) + ``` + + `accumulatedValue` - The value returned from the last time + `removedItem` or `addedItem` was called or `initialValue`. + + `item` - the element added or removed from the array + + `changeMeta` - An object which contains meta information about the + change. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + - `index` the index of the added or removed item + - `item` the added or removed item: this is exactly the same as + the second arg + - `arrayChanged` the array that triggered the change. Can be + useful when depending on multiple arrays. + + For property changes triggered on an item property change (when + depKey is something like `someArray.@each.someProperty`), + `changeMeta` will also contain the following property: + + - `previousValues` an object whose keys are the properties that changed on + the item, and whose values are the item's previous values. + + `previousValues` is important Ember coalesces item property changes via + Ember.run.once. This means that by the time removedItem gets called, item has + the new values, but you may need the previous value (eg for sorting & + filtering). + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + The `removedItem` and `addedItem` functions should return the accumulated + value. It is acceptable to not return anything (ie return undefined) + to invalidate the computation. This is generally not a good idea for + arrayComputed but it's used in eg max and min. + + Note that observers will be fired if either of these functions return a value + that differs from the accumulated value. When returning an object that + mutates in response to array changes, for example an array that maps + everything from some other array (see `Ember.computed.map`), it is usually + important that the *same* array be returned to avoid accidentally triggering observers. + + Example + + ```javascript + Ember.computed.max = function (dependentKey) { + return Ember.reduceComputed(dependentKey, { + initialValue: -Infinity, + + addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) { + return Math.max(accumulatedValue, item); + }, + + removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) { + if (item < accumulatedValue) { + return accumulatedValue; + } + } + }); + }; + ``` + + Dependent keys may refer to `@this` to observe changes to the object itself, + which must be array-like, rather than a property of the object. This is + mostly useful for array proxies, to ensure objects are retrieved via + `objectAtContent`. This is how you could sort items by properties defined on an item controller. + + Example + + ```javascript + App.PeopleController = Ember.ArrayController.extend({ + itemController: 'person', + + sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) { + // `reversedName` isn't defined on Person, but we have access to it via + // the item controller App.PersonController. If we'd used + // `content.@each.reversedName` above, we would be getting the objects + // directly and not have access to `reversedName`. + // + var reversedNameA = get(personA, 'reversedName'), + reversedNameB = get(personB, 'reversedName'); + + return Ember.compare(reversedNameA, reversedNameB); + }) + }); + + App.PersonController = Ember.ObjectController.extend({ + reversedName: function () { + return reverse(get(this, 'name')); + }.property('name') + }) + ``` + + Dependent keys whose values are not arrays are treated as regular + dependencies: when they change, the computed property is completely + recalculated. It is sometimes useful to have dependent arrays with similar + semantics. Dependent keys which end in `.[]` do not use "one at a time" + semantics. When an item is added or removed from such a dependency, the + computed property is completely recomputed. + + When the computed property is completely recomputed, the `accumulatedValue` + is discarded, it starts with `initialValue` again, and each item is passed + to `addedItem` in turn. + + Example + + ```javascript + Ember.Object.extend({ + // When `string` is changed, `computed` is completely recomputed. + string: 'a string', + + // When an item is added to `array`, `addedItem` is called. + array: [], + + // When an item is added to `anotherArray`, `computed` is completely + // recomputed. + anotherArray: [], + + computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', { + addedItem: addedItemCallback, + removedItem: removedItemCallback + }) + }); + ``` + + @method reduceComputed + @for Ember + @param {String} [dependentKeys*] + @param {Object} options + @return {Ember.ComputedProperty} + */ + function reduceComputed(options) { + var args; + + if (arguments.length > 1) { + args = a_slice.call(arguments, 0, -1); + options = a_slice.call(arguments, -1)[0]; + } + + if (typeof options !== "object") { + throw new EmberError("Reduce Computed Property declared without an options hash"); + } + + if (!('initialValue' in options)) { + throw new EmberError("Reduce Computed Property declared without an initial value"); + } + + var cp = new ReduceComputedProperty(options); + + if (args) { + cp.property.apply(cp, args); + } + + return cp; + } + + __exports__.reduceComputed = reduceComputed; + __exports__.ReduceComputedProperty = ReduceComputedProperty; + }); +define("ember-runtime/computed/reduce_computed_macros", + ["ember-metal/core","ember-metal/merge","ember-metal/property_get","ember-metal/property_set","ember-metal/utils","ember-metal/error","ember-metal/enumerable_utils","ember-metal/run_loop","ember-metal/observer","ember-runtime/computed/array_computed","ember-runtime/computed/reduce_computed","ember-runtime/system/object_proxy","ember-runtime/system/subarray","ember-runtime/keys","ember-runtime/compare","exports"], + function(__dependency1__, __dependency2__, __dependency3__, __dependency4__, __dependency5__, __dependency6__, __dependency7__, __dependency8__, __dependency9__, __dependency10__, __dependency11__, __dependency12__, __dependency13__, __dependency14__, __dependency15__, __exports__) { + "use strict"; + /** + @module ember + @submodule ember-runtime + */ + + var Ember = __dependency1__["default"]; + // Ember.assert + var merge = __dependency2__["default"]; + var get = __dependency3__.get; + var set = __dependency4__.set; + var isArray = __dependency5__.isArray; + var guidFor = __dependency5__.guidFor; + var EmberError = __dependency6__["default"]; + var EnumerableUtils = __dependency7__["default"]; + var run = __dependency8__["default"]; + var addObserver = __dependency9__.addObserver; + var arrayComputed = __dependency10__.arrayComputed; + var reduceComputed = __dependency11__.reduceComputed; + var ObjectProxy = __dependency12__["default"]; + var SubArray = __dependency13__["default"]; + var keys = __dependency14__["default"]; + var compare = __dependency15__["default"]; + + var a_slice = [].slice, + forEach = EnumerableUtils.forEach, + SearchProxy; + + /** + A computed property that returns the sum of the value + in the dependent array. + + @method computed.sum + @for Ember + @param {String} dependentKey + @return {Ember.ComputedProperty} computes the sum of all values in the dependentKey's array + @since 1.4.0 + */ + + function sum(dependentKey){ + return reduceComputed(dependentKey, { + initialValue: 0, + + addedItem: function(accumulatedValue, item, changeMeta, instanceMeta){ + return accumulatedValue + item; + }, + + removedItem: function(accumulatedValue, item, changeMeta, instanceMeta){ + return accumulatedValue - item; + } + }); + }; + + /** + A computed property that calculates the maximum value in the + dependent array.

This is one of the fundamental ways that + models, controllers and views communicate with each other in an Ember + application. + + Any object that has this mixin applied can be used in observer + operations. That includes `Ember.Object` and most objects you will + interact with as you write your Ember application. + + Note that you will not generally apply this mixin to classes yourself, + but you will use the features provided by this module frequently, so it + is important to understand how to use it. + + ## Using `get()` and `set()` + + Because of Ember's support for bindings and observers, you will always + access properties using the get method, and set properties using the + set method. This allows the observing objects to be notified and + computed properties to be handled properly. + + More documentation about `get` and `set` are below. + + ## Observing Property Changes + + You typically observe property changes simply by adding the `observes` + call to the end of your method declarations in classes that you write. + For example: + + ```javascript + Ember.Object.extend({ + valueObserver: function() { + // Executes whenever the "value" property changes + }.observes('value') + }); + ``` + + Although this is the most common way to add an observer, this capability + is actually built into the `Ember.Object` class on top of two methods + defined in this mixin: `addObserver` and `removeObserver`. You can use + these two methods to add and remove observers yourself if you need to + do so at runtime. + + To add an observer for a property, call: + + ```javascript + object.addObserver('propertyKey', targetObject, targetAction) + ``` + + This will call the `targetAction` method on the `targetObject` whenever + the value of the `propertyKey` changes. + + Note that if `propertyKey` is a computed property, the observer will be + called when any of the property dependencies are changed, even if the + resulting value of the computed property is unchanged. This is necessary + because computed properties are not computed until `get` is called. + + @class Observable + @namespace Ember + */ + var Observable = Mixin.create({ + + /** + Retrieves the value of a property from the object. + + This method is usually similar to using `object[keyName]` or `object.keyName`, + however it supports both computed properties and the unknownProperty + handler. + + Because `get` unifies the syntax for accessing all these kinds + of properties, it can make many refactorings easier, such as replacing a + simple property with a computed property, or vice versa. + + ### Computed Properties + + Computed properties are methods defined with the `property` modifier + declared at the end, such as: + + ```javascript + fullName: function() { + return this.get('firstName') + ' ' + this.get('lastName'); + }.property('firstName', 'lastName') + ``` + + When you call `get` on a computed property, the function will be + called and the return value will be returned instead of the function + itself. + + ### Unknown Properties + + Likewise, if you try to call `get` on a property whose value is + `undefined`, the `unknownProperty()` method will be called on the object. + If this method returns any value other than `undefined`, it will be returned + instead. This allows you to implement "virtual" properties that are + not defined upfront. + + @method get + @param {String} keyName The property to retrieve + @return {Object} The property value or undefined. + */ + get: function(keyName) { + return get(this, keyName); + }, + + /** + To get multiple properties at once, call `getProperties` + with a list of strings or an array: + + ```javascript + record.getProperties('firstName', 'lastName', 'zipCode'); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' } + ``` + + is equivalent to: + + ```javascript + record.getProperties(['firstName', 'lastName', 'zipCode']); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' } + ``` + + @method getProperties + @param {String...|Array} list of keys to get + @return {Hash} + */ + getProperties: function() { + return apply(null, getProperties, [this].concat(slice.call(arguments))); + }, + + /** + Sets the provided key or path to the value. + + This method is generally very similar to calling `object[key] = value` or + `object.key = value`, except that it provides support for computed + properties, the `setUnknownProperty()` method and property observers. + + ### Computed Properties + + If you try to set a value on a key that has a computed property handler + defined (see the `get()` method for an example), then `set()` will call + that method, passing both the value and key instead of simply changing + the value itself. This is useful for those times when you need to + implement a property that is composed of one or more member + properties. + + ### Unknown Properties + + If you try to set a value on a key that is undefined in the target + object, then the `setUnknownProperty()` handler will be called instead. This + gives you an opportunity to implement complex "virtual" properties that + are not predefined on the object. If `setUnknownProperty()` returns + undefined, then `set()` will simply set the value on the object. + + ### Property Observers + + In addition to changing the property, `set()` will also register a property + change with the object. Unless you have placed this call inside of a + `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers + (i.e. observer methods declared on the same object), will be called + immediately. Any "remote" observers (i.e. observer methods declared on + another object) will be placed in a queue and called at a later time in a + coalesced manner. + + ### Chaining + + In addition to property changes, `set()` returns the value of the object + itself so you can do chaining like this: + + ```javascript + record.set('firstName', 'Charles').set('lastName', 'Jolley'); + ``` + + @method set + @param {String} keyName The property to set + @param {Object} value The value to set or `null`. + @return {Ember.Observable} + */ + set: function(keyName, value) { + set(this, keyName, value); + return this; + }, + + + /** + Sets a list of properties at once.

You can + also iterate through a set just like an array, even accessing objects by + index, however there is no guarantee as to their order. + + All Sets are observable via the Enumerable Observer API - which works + on any enumerable object including both Sets and Arrays. + + ## Creating a Set + + You can create a set like you would most objects using + `new Ember.Set()`. Most new sets you create will be empty, but you can + also initialize the set with some content by passing an array or other + enumerable of objects to the constructor. + + Finally, you can pass in an existing set and the set will be copied. You + can also create a copy of a set by calling `Ember.Set#copy()`. + + ```javascript + // creates a new empty set + var foundNames = new Ember.Set(); + + // creates a set with four names in it. + var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P + + // creates a copy of the names set. + var namesCopy = new Ember.Set(names); + + // same as above. + var anotherNamesCopy = names.copy(); + ``` + + ## Adding/Removing Objects + + You generally add or remove objects from a set using `add()` or + `remove()`. You can add any type of object including primitives such as + numbers, strings, and booleans. + + Unlike arrays, objects can only exist one time in a set. If you call `add()` + on a set with the same object multiple times, the object will only be added + once. Likewise, calling `remove()` with the same object multiple times will + remove the object the first time and have no effect on future calls until + you add the object to the set again. + + NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do + so will be ignored. + + In addition to add/remove you can also call `push()`/`pop()`. Push behaves + just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary + object, remove it and return it. This is a good way to use a set as a job + queue when you don't care which order the jobs are executed in. + + ## Testing for an Object + + To test for an object's presence in a set you simply call + `Ember.Set#contains()`. + + ## Observing changes + + When using `Ember.Set`, you can observe the `"[]"` property to be + alerted whenever the content changes. You can also add an enumerable + observer to the set to be notified of specific objects that are added and + removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html) + for more information on enumerables. + + This is often unhelpful. If you are filtering sets of objects, for instance, + it is very inefficient to re-filter all of the items each time the set + changes. It would be better if you could just adjust the filtered set based + on what was changed on the original set. The same issue applies to merging + sets, as well. + + ## Other Methods + + `Ember.Set` primary implements other mixin APIs. For a complete reference + on the methods you will use with `Ember.Set`, please consult these mixins. + The most useful ones will be `Ember.Enumerable` and + `Ember.MutableEnumerable` which implement most of the common iterator + methods you are used to on Array. + + Note that you can also use the `Ember.Copyable` and `Ember.Freezable` + APIs on `Ember.Set` as well. Once a set is frozen it can no longer be + modified. The benefit of this is that when you call `frozenCopy()` on it, + Ember will avoid making copies of the set.

    + ``` + + `class` attribute values can also be set by providing a `classNameBindings` + property set to an array of properties names for the view. The return value + of these properties will be added as part of the value for the view's `class` + attribute. These properties can be computed properties: + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['propertyA', 'propertyB'], + propertyA: 'from-a', + propertyB: function() { + if (someLogic) { return 'from-b'; } + }.property() + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + If the value of a class name binding returns a boolean the property name + itself will be used as the class name if the property is true. The class name + will not be added if the value is `false` or `undefined`. + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['hovered'], + hovered: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + When using boolean class name bindings you can supply a string value other + than the property name for use as the `class` HTML attribute by appending the + preferred value after a ":" character when defining the binding: + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['awesome:so-very-cool'], + awesome: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + Boolean value class name bindings whose property names are in a + camelCase-style format will be converted to a dasherized format: + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['isUrgent'], + isUrgent: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + Class name bindings can also refer to object values that are found by + traversing a path relative to the view itself: + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['messages.empty'] + messages: Ember.Object.create({ + empty: true + }) + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + If you want to add a class name for a property which evaluates to true and + and a different class name if it evaluates to false, you can pass a binding + like this: + + ```javascript + // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false + Ember.View.extend({ + classNameBindings: ['isEnabled:enabled:disabled'] + isEnabled: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + When isEnabled is `false`, the resulting HTML reprensentation looks like + this: + + ```html +
    + ``` + + This syntax offers the convenience to add a class if a property is `false`: + + ```javascript + // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false + Ember.View.extend({ + classNameBindings: ['isEnabled::disabled'] + isEnabled: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + When the `isEnabled` property on the view is set to `false`, it will result + in view instances with an HTML representation of: + + ```html +
    + ``` + + Updates to the the value of a class name binding will result in automatic + update of the HTML `class` attribute in the view's rendered HTML + representation. If the value becomes `false` or `undefined` the class name + will be removed. + + Both `classNames` and `classNameBindings` are concatenated properties. See + [Ember.Object](/api/classes/Ember.Object.html) documentation for more + information about concatenated properties. + + ## HTML Attributes + + The HTML attribute section of a view's tag can be set by providing an + `attributeBindings` property set to an array of property names on the view. + The return value of these properties will be used as the value of the view's + HTML associated attribute: + + ```javascript + AnchorView = Ember.View.extend({ + tagName: 'a', + attributeBindings: ['href'], + href: 'http://google.com' + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + One property can be mapped on to another by placing a ":" between + the source property and the destination property: + + ```javascript + AnchorView = Ember.View.extend({ + tagName: 'a', + attributeBindings: ['url:href'], + url: 'http://google.com' + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + If the return value of an `attributeBindings` monitored property is a boolean + the property will follow HTML's pattern of repeating the attribute's name as + its value: + + ```javascript + MyTextInput = Ember.View.extend({ + tagName: 'input', + attributeBindings: ['disabled'], + disabled: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + `attributeBindings` can refer to computed properties: + + ```javascript + MyTextInput = Ember.View.extend({ + tagName: 'input', + attributeBindings: ['disabled'], + disabled: function() { + if (someLogic) { + return true; + } else { + return false; + } + }.property() + }); + ``` + + Updates to the the property of an attribute binding will result in automatic + update of the HTML attribute in the view's rendered HTML representation. + + `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html) + documentation for more information about concatenated properties. + + ## Templates + + The HTML contents of a view's rendered representation are determined by its + template. Templates can be any function that accepts an optional context + parameter and returns a string of HTML that will be inserted within the + view's tag. Most typically in Ember this function will be a compiled + `Ember.Handlebars` template. + + ```javascript + AView = Ember.View.extend({ + template: Ember.Handlebars.compile('I am the template') + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    I am the template
    + ``` + + Within an Ember application is more common to define a Handlebars templates as + part of a page: + + ```html + + ``` + + And associate it by name using a view's `templateName` property: + + ```javascript + AView = Ember.View.extend({ + templateName: 'some-template' + }); + ``` + + If you have nested resources, your Handlebars template will look like this: + + ```html + + ``` + + And `templateName` property: + + ```javascript + AView = Ember.View.extend({ + templateName: 'posts/new' + }); + ``` + + Using a value for `templateName` that does not have a Handlebars template + with a matching `data-template-name` attribute will throw an error. + + For views classes that may have a template later defined (e.g. as the block + portion of a `{{view}}` Handlebars helper call in another template or in + a subclass), you can provide a `defaultTemplate` property set to compiled + template function. If a template is not later provided for the view instance + the `defaultTemplate` value will be used: + + ```javascript + AView = Ember.View.extend({ + defaultTemplate: Ember.Handlebars.compile('I was the default'), + template: null, + templateName: null + }); + ``` + + Will result in instances with an HTML representation of: + + ```html +
    I was the default
    + ``` + + If a `template` or `templateName` is provided it will take precedence over + `defaultTemplate`: + + ```javascript + AView = Ember.View.extend({ + defaultTemplate: Ember.Handlebars.compile('I was the default') + }); + + aView = AView.create({ + template: Ember.Handlebars.compile('I was the template, not default') + }); + ``` + + Will result in the following HTML representation when rendered: + + ```html +
    I was the template, not default
    + ``` + + ## View Context + + The default context of the compiled template is the view's controller: + + ```javascript + AView = Ember.View.extend({ + template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') + }); + + aController = Ember.Object.create({ + firstName: 'Barry', + excitedGreeting: function() { + return this.get("content.firstName") + "!!!" + }.property() + }); + + aView = AView.create({ + controller: aController, + }); + ``` + + Will result in an HTML representation of: + + ```html +
    Hello Barry!!!
    + ``` + + A context can also be explicitly supplied through the view's `context` + property. If the view has neither `context` nor `controller` properties, the + `parentView`'s context will be used. + + ## Layouts + + Views can have a secondary template that wraps their main template. Like + primary templates, layouts can be any function that accepts an optional + context parameter and returns a string of HTML that will be inserted inside + view's tag. Views whose HTML element is self closing (e.g. ``) + cannot have a layout and this property will be ignored. + + Most typically in Ember a layout will be a compiled `Ember.Handlebars` + template. + + A view's layout can be set directly with the `layout` property or reference + an existing Handlebars template by name with the `layoutName` property. + + A template used as a layout must contain a single use of the Handlebars + `{{yield}}` helper. The HTML contents of a view's rendered `template` will be + inserted at this location: + + ```javascript + AViewWithLayout = Ember.View.extend({ + layout: Ember.Handlebars.compile("
    {{yield}}
    ") + template: Ember.Handlebars.compile("I got wrapped"), + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    +
    + I got wrapped +
    +
    + ``` + + See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) + for more information. + + ## Responding to Browser Events + + Views can respond to user-initiated events in one of three ways: method + implementation, through an event manager, and through `{{action}}` helper use + in their template or layout. + + ### Method Implementation + + Views can respond to user-initiated events by implementing a method that + matches the event name. A `jQuery.Event` object will be passed as the + argument to this method. + + ```javascript + AView = Ember.View.extend({ + click: function(event) { + // will be called when when an instance's + // rendered element is clicked + } + }); + ``` + + ### Event Managers + + Views can define an object as their `eventManager` property. This object can + then implement methods that match the desired event names. Matching events + that occur on the view's rendered HTML or the rendered HTML of any of its DOM + descendants will trigger this method. A `jQuery.Event` object will be passed + as the first argument to the method and an `Ember.View` object as the + second. The `Ember.View` will be the view whose rendered HTML was interacted + with. This may be the view with the `eventManager` property or one of its + descendent views. + + ```javascript + AView = Ember.View.extend({ + eventManager: Ember.Object.create({ + doubleClick: function(event, view) { + // will be called when when an instance's + // rendered element or any rendering + // of this views's descendent + // elements is clicked + } + }) + }); + ``` + + An event defined for an event manager takes precedence over events of the + same name handled through methods on the view. + + ```javascript + AView = Ember.View.extend({ + mouseEnter: function(event) { + // will never trigger. + }, + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // takes precedence over AView#mouseEnter + } + }) + }); + ``` + + Similarly a view's event manager will take precedence for events of any views + rendered as a descendent. A method name that matches an event name will not + be called if the view instance was rendered inside the HTML representation of + a view that has an `eventManager` property defined that handles events of the + name. Events not handled by the event manager will still trigger method calls + on the descendent. + + ```javascript + OuterView = Ember.View.extend({ + template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"), + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // view might be instance of either + // OuterView or InnerView depending on + // where on the page the user interaction occured + } + }) + }); + + InnerView = Ember.View.extend({ + click: function(event) { + // will be called if rendered inside + // an OuterView because OuterView's + // eventManager doesn't handle click events + }, + mouseEnter: function(event) { + // will never be called if rendered inside + // an OuterView. + } + }); + ``` + + ### Handlebars `{{action}}` Helper + + See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). + + ### Event Names + + All of the event handling approaches described above respond to the same set + of events. The names of the built-in events are listed below. (The hash of + built-in events exists in `Ember.EventDispatcher`.) Additional, custom events + can be registered by using `Ember.Application.customEvents`. + + Touch events: + + * `touchStart` + * `touchMove` + * `touchEnd` + * `touchCancel` + + Keyboard events + + * `keyDown` + * `keyUp` + * `keyPress` + + Mouse events + + * `mouseDown` + * `mouseUp` + * `contextMenu` + * `click` + * `doubleClick` + * `mouseMove` + * `focusIn` + * `focusOut` + * `mouseEnter` + * `mouseLeave` + + Form events: + + * `submit` + * `change` + * `focusIn` + * `focusOut` + * `input` + + HTML5 drag and drop events: + + * `dragStart` + * `drag` + * `dragEnter` + * `dragLeave` + * `dragOver` + * `dragEnd` + * `drop` + + ## Handlebars `{{view}}` Helper + + Other `Ember.View` instances can be included as part of a view's template by + using the `{{view}}` Handlebars helper.

    + ``` + + `{{with}}` can be our best friend in these cases, + instead of writing `user.role.*` over and over, we use `{{#with user.role}}`. + Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following: + + ```handlebars +
    {{user.name}}
    + +
    + {{#with user.role}} +
    {{label}}
    + {{id}} + +

    {{description}}

    + {{/with}} +
    + ``` + + ### `as` operator + + This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain + default scope or to reference from another `{{with}}` block. + + ```handlebars + // posts might not be + {{#with user.posts as blogPosts}} +
    + There are {{blogPosts.length}} blog posts written by {{user.name}}. +
    + + {{#each post in blogPosts}} +
  • {{post.title}}
    • + {{/each}} + {{/with}} + ``` + + Without the `as` operator, it would be impossible to reference `user.name` in the example above. + + NOTE: The alias should not reuse a name from the bound property path. + For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using + the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`. + + ### `controller` option + + Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of + the specified controller with the new context as its content. + + This is very similar to using an `itemController` option with the `{{each}}` helper. + + ```handlebars + {{#with users.posts controller='userBlogPosts'}} + {{!- The current context is wrapped in our controller instance }} + {{/with}} + ``` + + In the above example, the template provided to the `{{with}}` block is now wrapped in the + `userBlogPost` controller, which provides a very elegant way to decorate the context with custom + functions/properties. + + @method with + @for Ember.Handlebars.helpers + @param {Function} context + @param {Hash} options + @return {String} HTML string + */ + function withHelper(context, options) { + var bindContext, preserveContext, controller, helperName = 'with'; + + if (arguments.length === 4) { + var keywordName, path, rootPath, normalized, contextPath; + + Ember.assert("If you pass more than one argument to the with helper, it must be in the form #with foo as bar", arguments[1] === "as"); + options = arguments[3]; + keywordName = arguments[2]; + path = arguments[0]; + + if (path) { + helperName += ' ' + path + ' as ' + keywordName; + } + + Ember.assert("You must pass a block to the with helper", options.fn && options.fn !== Handlebars.VM.noop); + + var localizedOptions = o_create(options); + localizedOptions.data = o_create(options.data); + localizedOptions.data.keywords = o_create(options.data.keywords || {}); + + if (isGlobalPath(path)) { + contextPath = path; + } else { + normalized = normalizePath(this, path, options.data); + path = normalized.path; + rootPath = normalized.root; + + // This is a workaround for the fact that you cannot bind separate objects + // together.

    +
    Greetings Dave
    +
    Greetings Mary
    +
    Greetings Sara
    +
    + ``` + + If an `itemViewClass` is defined on the helper, and therefore the helper is not + being used as a block, an `emptyViewClass` can also be provided optionally. + The `emptyViewClass` will match the behavior of the `{{else}}` condition + described above. That is, the `emptyViewClass` will render if the collection + is empty. + + ### Representing each item with a Controller. + By default the controller lookup within an `{{#each}}` block will be + the controller of the template where the `{{#each}}` was used. If each + item needs to be presented by a custom controller you can provide a + `itemController` option which references a controller by lookup name. + Each item in the loop will be wrapped in an instance of this controller + and the item itself will be set to the `content` property of that controller. + + This is useful in cases where properties of model objects need transformation + or synthesis for display: + + ```javascript + App.DeveloperController = Ember.ObjectController.extend({ + isAvailableForHire: function() { + return !this.get('content.isEmployed') && this.get('content.isSeekingWork'); + }.property('isEmployed', 'isSeekingWork') + }) + ``` + + ```handlebars + {{#each person in developers itemController="developer"}} + {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} + {{/each}} + ``` + + Each itemController will receive a reference to the current controller as + a `parentController` property. + + ### (Experimental) Grouped Each + + When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper), + you can inform Handlebars to re-render an entire group of items instead of + re-rendering them one at a time (in the event that they are changed en masse + or an item is added/removed). + + ```handlebars + {{#group}} + {{#each people}} + {{firstName}} {{lastName}} + {{/each}} + {{/group}} + ``` + + This can be faster than the normal way that Handlebars re-renders items + in some cases. + + If for some reason you have a group with more than one `#each`, you can make + one of the collections be updated in normal (non-grouped) fashion by setting + the option `groupedRows=true` (counter-intuitive, I know). + + For example, + + ```handlebars + {{dealershipName}} + + {{#group}} + {{#each dealers}} + {{firstName}} {{lastName}} + {{/each}} + + {{#each car in cars groupedRows=true}} + {{car.make}} {{car.model}} {{car.color}} + {{/each}} + {{/group}} + ``` + Any change to `dealershipName` or the `dealers` collection will cause the + entire group to be re-rendered. However, changes to the `cars` collection + will be re-rendered individually (as normal). + + Note that `group` behavior is also disabled by specifying an `itemViewClass`. + + @method each + @for Ember.Handlebars.helpers + @param [name] {String} name for item (used with `in`) + @param [path] {String} path + @param [options] {Object} Handlebars key/value pairs of options + @param [options.itemViewClass] {String} a path to a view class used for each item + @param [options.itemController] {String} name of a controller to be created for each item + @param [options.groupedRows] {boolean} enable normal item-by-item rendering when inside a `#group` helper + */ + function eachHelper(path, options) { + var ctx, helperName = 'each'; + + if (arguments.length === 4) { + Ember.assert("If you pass more than one argument to the each helper, it must be in the form #each foo in bar", arguments[1] === "in"); + + var keywordName = arguments[0]; + + + options = arguments[3]; + path = arguments[2]; + + helperName += ' ' + keywordName + ' in ' + path; + + if (path === '') { path = "this"; } + + options.hash.keyword = keywordName; + + } else if (arguments.length === 1) { + options = path; + path = 'this'; + } else { + helperName += ' ' + path; + } + + options.hash.dataSourceBinding = path; + // Set up emptyView as a metamorph with no tag + //options.hash.emptyViewClass = Ember._MetamorphView; + + // can't rely on this default behavior when use strict + ctx = this || window; + + options.helperName = options.helperName || helperName; + + if (options.data.insideGroup && !options.hash.groupedRows && !options.hash.itemViewClass) { + new GroupedEach(ctx, path, options).render(); + } else { + // ES6TODO: figure out how to do this without global lookup. + return helpers.collection.call(ctx, 'Ember.Handlebars.EachView', options); + } + } + + __exports__.EachView = EachView; + __exports__.GroupedEach = GroupedEach; + __exports__.eachHelper = eachHelper; + }); +define("ember-handlebars/helpers/loc", + ["ember-runtime/system/string","exports"], + function(__dependency1__, __exports__) { + "use strict"; + var loc = __dependency1__.loc; + + /** + @module ember + @submodule ember-handlebars + */ + + // ES6TODO: + // Pretty sure this can be expressed as + // var locHelper EmberStringUtils.loc ? + + /** + Calls [Ember.String.loc](/api/classes/Ember.String.html#method_loc) with the + provided string. + + This is a convenient way to localize text.

    - ``` - - `class` attribute values can also be set by providing a `classNameBindings` - property set to an array of properties names for the view. The return value - of these properties will be added as part of the value for the view's `class` - attribute. These properties can be computed properties: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['propertyA', 'propertyB'], - propertyA: 'from-a', - propertyB: function() { - if (someLogic) { return 'from-b'; } - }.property() - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - If the value of a class name binding returns a boolean the property name - itself will be used as the class name if the property is true. The class name - will not be added if the value is `false` or `undefined`. - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['hovered'], - hovered: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - When using boolean class name bindings you can supply a string value other - than the property name for use as the `class` HTML attribute by appending the - preferred value after a ":" character when defining the binding: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['awesome:so-very-cool'], - awesome: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - Boolean value class name bindings whose property names are in a - camelCase-style format will be converted to a dasherized format: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['isUrgent'], - isUrgent: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - Class name bindings can also refer to object values that are found by - traversing a path relative to the view itself: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['messages.empty'] - messages: Ember.Object.create({ - empty: true - }) - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - If you want to add a class name for a property which evaluates to true and - and a different class name if it evaluates to false, you can pass a binding - like this: - - ```javascript - // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled:enabled:disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - When isEnabled is `false`, the resulting HTML reprensentation looks like - this: - - ```html -
    - ``` - - This syntax offers the convenience to add a class if a property is `false`: - - ```javascript - // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled::disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - When the `isEnabled` property on the view is set to `false`, it will result - in view instances with an HTML representation of: - - ```html -
    - ``` - - Updates to the the value of a class name binding will result in automatic - update of the HTML `class` attribute in the view's rendered HTML - representation. If the value becomes `false` or `undefined` the class name - will be removed. - - Both `classNames` and `classNameBindings` are concatenated properties. See - [Ember.Object](/api/classes/Ember.Object.html) documentation for more - information about concatenated properties. - - ## HTML Attributes - - The HTML attribute section of a view's tag can be set by providing an - `attributeBindings` property set to an array of property names on the view. - The return value of these properties will be used as the value of the view's - HTML associated attribute: - - ```javascript - AnchorView = Ember.View.extend({ - tagName: 'a', - attributeBindings: ['href'], - href: 'http://google.com' - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - - ``` - - One property can be mapped on to another by placing a ":" between - the source property and the destination property: - - ```javascript - AnchorView = Ember.View.extend({ - tagName: 'a', - attributeBindings: ['url:href'], - url: 'http://google.com' - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - - ``` - - If the return value of an `attributeBindings` monitored property is a boolean - the property will follow HTML's pattern of repeating the attribute's name as - its value: - - ```javascript - MyTextInput = Ember.View.extend({ - tagName: 'input', - attributeBindings: ['disabled'], - disabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - - ``` - - `attributeBindings` can refer to computed properties: - - ```javascript - MyTextInput = Ember.View.extend({ - tagName: 'input', - attributeBindings: ['disabled'], - disabled: function() { - if (someLogic) { - return true; - } else { - return false; - } - }.property() - }); - ``` - - Updates to the the property of an attribute binding will result in automatic - update of the HTML attribute in the view's rendered HTML representation. - - `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html) - documentation for more information about concatenated properties. - - ## Templates - - The HTML contents of a view's rendered representation are determined by its - template. Templates can be any function that accepts an optional context - parameter and returns a string of HTML that will be inserted within the - view's tag. Most typically in Ember this function will be a compiled - `Ember.Handlebars` template. - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('I am the template') - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    I am the template
    - ``` - - Within an Ember application is more common to define a Handlebars templates as - part of a page: - - ```html - - ``` - - And associate it by name using a view's `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'some-template' - }); - ``` - - If you have nested resources, your Handlebars template will look like this: - - ```html - - ``` - - And `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'posts/new' - }); - ``` - - Using a value for `templateName` that does not have a Handlebars template - with a matching `data-template-name` attribute will throw an error. - - For views classes that may have a template later defined (e.g. as the block - portion of a `{{view}}` Handlebars helper call in another template or in - a subclass), you can provide a `defaultTemplate` property set to compiled - template function. If a template is not later provided for the view instance - the `defaultTemplate` value will be used: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default'), - template: null, - templateName: null - }); - ``` - - Will result in instances with an HTML representation of: - - ```html -
    I was the default
    - ``` - - If a `template` or `templateName` is provided it will take precedence over - `defaultTemplate`: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default') - }); - - aView = AView.create({ - template: Ember.Handlebars.compile('I was the template, not default') - }); - ``` - - Will result in the following HTML representation when rendered: - - ```html -
    I was the template, not default
    - ``` - - ## View Context - - The default context of the compiled template is the view's controller: - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') - }); - - aController = Ember.Object.create({ - firstName: 'Barry', - excitedGreeting: function() { - return this.get("content.firstName") + "!!!" - }.property() - }); - - aView = AView.create({ - controller: aController, - }); - ``` - - Will result in an HTML representation of: - - ```html -
    Hello Barry!!!
    - ``` - - A context can also be explicitly supplied through the view's `context` - property. If the view has neither `context` nor `controller` properties, the - `parentView`'s context will be used. - - ## Layouts - - Views can have a secondary template that wraps their main template. Like - primary templates, layouts can be any function that accepts an optional - context parameter and returns a string of HTML that will be inserted inside - view's tag. Views whose HTML element is self closing (e.g. ``) - cannot have a layout and this property will be ignored. - - Most typically in Ember a layout will be a compiled `Ember.Handlebars` - template. - - A view's layout can be set directly with the `layout` property or reference - an existing Handlebars template by name with the `layoutName` property. - - A template used as a layout must contain a single use of the Handlebars - `{{yield}}` helper. The HTML contents of a view's rendered `template` will be - inserted at this location: - - ```javascript - AViewWithLayout = Ember.View.extend({ - layout: Ember.Handlebars.compile("
    {{yield}}
    ") - template: Ember.Handlebars.compile("I got wrapped"), - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    -
    - I got wrapped -
    -
    - ``` - - See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) - for more information. - - ## Responding to Browser Events - - Views can respond to user-initiated events in one of three ways: method - implementation, through an event manager, and through `{{action}}` helper use - in their template or layout. - - ### Method Implementation - - Views can respond to user-initiated events by implementing a method that - matches the event name. A `jQuery.Event` object will be passed as the - argument to this method. - - ```javascript - AView = Ember.View.extend({ - click: function(event) { - // will be called when when an instance's - // rendered element is clicked - } - }); - ``` - - ### Event Managers - - Views can define an object as their `eventManager` property. This object can - then implement methods that match the desired event names. Matching events - that occur on the view's rendered HTML or the rendered HTML of any of its DOM - descendants will trigger this method. A `jQuery.Event` object will be passed - as the first argument to the method and an `Ember.View` object as the - second. The `Ember.View` will be the view whose rendered HTML was interacted - with. This may be the view with the `eventManager` property or one of its - descendent views. - - ```javascript - AView = Ember.View.extend({ - eventManager: Ember.Object.create({ - doubleClick: function(event, view) { - // will be called when when an instance's - // rendered element or any rendering - // of this views's descendent - // elements is clicked - } - }) - }); - ``` - - An event defined for an event manager takes precedence over events of the - same name handled through methods on the view. - - ```javascript - AView = Ember.View.extend({ - mouseEnter: function(event) { - // will never trigger. - }, - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // takes precedence over AView#mouseEnter - } - }) - }); - ``` - - Similarly a view's event manager will take precedence for events of any views - rendered as a descendent. A method name that matches an event name will not - be called if the view instance was rendered inside the HTML representation of - a view that has an `eventManager` property defined that handles events of the - name. Events not handled by the event manager will still trigger method calls - on the descendent. - - ```javascript - OuterView = Ember.View.extend({ - template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"), - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // view might be instance of either - // OuterView or InnerView depending on - // where on the page the user interaction occured - } - }) - }); - - InnerView = Ember.View.extend({ - click: function(event) { - // will be called if rendered inside - // an OuterView because OuterView's - // eventManager doesn't handle click events - }, - mouseEnter: function(event) { - // will never be called if rendered inside - // an OuterView. - } - }); - ``` - - ### Handlebars `{{action}}` Helper - - See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). - - ### Event Names - - All of the event handling approaches described above respond to the same set - of events. The names of the built-in events are listed below. (The hash of - built-in events exists in `Ember.EventDispatcher`.) Additional, custom events - can be registered by using `Ember.Application.customEvents`. - - Touch events: - - * `touchStart` - * `touchMove` - * `touchEnd` - * `touchCancel` - - Keyboard events - - * `keyDown` - * `keyUp` - * `keyPress` - - Mouse events - - * `mouseDown` - * `mouseUp` - * `contextMenu` - * `click` - * `doubleClick` - * `mouseMove` - * `focusIn` - * `focusOut` - * `mouseEnter` - * `mouseLeave` - - Form events: - - * `submit` - * `change` - * `focusIn` - * `focusOut` - * `input` - - HTML5 drag and drop events: - - * `dragStart` - * `drag` - * `dragEnter` - * `dragLeave` - * `dragOver` - * `dragEnd` - * `drop` - - ## Handlebars `{{view}}` Helper - - Other `Ember.View` instances can be included as part of a view's template by - using the `{{view}}` Handlebars helper.

    - ``` - - `{{with}}` can be our best friend in these cases, - instead of writing `user.role.*` over and over, we use `{{#with user.role}}`. - Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following: - - ```handlebars -
    {{user.name}}
    - -
    - {{#with user.role}} -
    {{label}}
    - {{id}} - -

    {{description}}

    - {{/with}} -
    - ``` - - ### `as` operator - - This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain - default scope or to reference from another `{{with}}` block. - - ```handlebars - // posts might not be - {{#with user.posts as blogPosts}} -
    - There are {{blogPosts.length}} blog posts written by {{user.name}}. -
    - - {{#each post in blogPosts}} -
  • {{post.title}}
    • - {{/each}} - {{/with}} - ``` - - Without the `as` operator, it would be impossible to reference `user.name` in the example above. - - NOTE: The alias should not reuse a name from the bound property path. - For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using - the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`. - - ### `controller` option - - Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of - the specified controller with the new context as its content. - - This is very similar to using an `itemController` option with the `{{each}}` helper. - - ```handlebars - {{#with users.posts controller='userBlogPosts'}} - {{!- The current context is wrapped in our controller instance }} - {{/with}} - ``` - - In the above example, the template provided to the `{{with}}` block is now wrapped in the - `userBlogPost` controller, which provides a very elegant way to decorate the context with custom - functions/properties. - - @method with - @for Ember.Handlebars.helpers - @param {Function} context - @param {Hash} options - @return {String} HTML string - */ - function withHelper(context, options) { - var bindContext, preserveContext, controller, helperName = 'with'; - - if (arguments.length === 4) { - var keywordName, path, rootPath, normalized, contextPath; - - Ember.assert("If you pass more than one argument to the with helper, it must be in the form #with foo as bar", arguments[1] === "as"); - options = arguments[3]; - keywordName = arguments[2]; - path = arguments[0]; - - if (path) { - helperName += ' ' + path + ' as ' + keywordName; - } - - Ember.assert("You must pass a block to the with helper", options.fn && options.fn !== Handlebars.VM.noop); - - var localizedOptions = o_create(options); - localizedOptions.data = o_create(options.data); - localizedOptions.data.keywords = o_create(options.data.keywords || {}); - - if (isGlobalPath(path)) { - contextPath = path; - } else { - normalized = normalizePath(this, path, options.data); - path = normalized.path; - rootPath = normalized.root; - - // This is a workaround for the fact that you cannot bind separate objects - // together.

The `class` attribute combines - multiple discrete values into a single attribute as a space-delimited - list of strings. Each string can be: - - * a string return value of an object's property. - * a boolean return value of an object's property - * a hard-coded value - - A string return value works identically to other uses of `bind-attr`. The - return value of the property will become the value of the attribute. For - example, the following view and template: - - ```javascript - AView = View.extend({ - someProperty: function() { - return "aValue"; - }.property() - }) - ``` - - ```handlebars - - ``` - - A boolean return value will insert a specified class name if the property - returns `true` and remove the class name if the property returns `false`. - - A class name is provided via the syntax - `somePropertyName:class-name-if-true`. - - ```javascript - AView = View.extend({ - someBool: true - }) - ``` - - ```handlebars - - ``` - - Result in the following rendered output: - - ```html - - ``` - - An additional section of the binding can be provided if you want to - replace the existing class instead of removing it when the boolean - value changes: - - ```handlebars - - ``` - - A hard-coded value can be used by prepending `:` to the desired - class name: `:class-name-to-always-apply`. - - ```handlebars - - ``` - - Results in the following rendered output: - - ```html - - ``` - - All three strategies - string return value, boolean return value, and - hard-coded value – can be combined in a single declaration: - - ```handlebars - - ``` - - @method bind-attr - @for Ember.Handlebars.helpers - @param {Hash} options - @return {String} HTML string - */ - function bindAttrHelper(options) { - var attrs = options.hash; - - Ember.assert("You must specify at least one hash argument to bind-attr", !!keys(attrs).length); - - var view = options.data.view; - var ret = []; - - // we relied on the behavior of calling without - // context to mean this === window, but when running - // "use strict", it's possible for this to === undefined; - var ctx = this || window; - - // Generate a unique id for this element.

    -
    - ``` - - If an `itemViewClass` is defined on the helper, and therefore the helper is not - being used as a block, an `emptyViewClass` can also be provided optionally. - The `emptyViewClass` will match the behavior of the `{{else}}` condition - described above. That is, the `emptyViewClass` will render if the collection - is empty. - - ### Representing each item with a Controller. - By default the controller lookup within an `{{#each}}` block will be - the controller of the template where the `{{#each}}` was used. If each - item needs to be presented by a custom controller you can provide a - `itemController` option which references a controller by lookup name. - Each item in the loop will be wrapped in an instance of this controller - and the item itself will be set to the `content` property of that controller. - - This is useful in cases where properties of model objects need transformation - or synthesis for display: - - ```javascript - App.DeveloperController = Ember.ObjectController.extend({ - isAvailableForHire: function() { - return !this.get('content.isEmployed') && this.get('content.isSeekingWork'); - }.property('isEmployed', 'isSeekingWork') - }) - ``` - - ```handlebars - {{#each person in developers itemController="developer"}} - {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} - {{/each}} - ``` - - Each itemController will receive a reference to the current controller as - a `parentController` property. - - ### (Experimental) Grouped Each - - When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper), - you can inform Handlebars to re-render an entire group of items instead of - re-rendering them one at a time (in the event that they are changed en masse - or an item is added/removed). - - ```handlebars - {{#group}} - {{#each people}} - {{firstName}} {{lastName}} - {{/each}} - {{/group}} - ``` - - This can be faster than the normal way that Handlebars re-renders items - in some cases. - - If for some reason you have a group with more than one `#each`, you can make - one of the collections be updated in normal (non-grouped) fashion by setting - the option `groupedRows=true` (counter-intuitive, I know). - - For example, - - ```handlebars - {{dealershipName}} - - {{#group}} - {{#each dealers}} - {{firstName}} {{lastName}} - {{/each}} - - {{#each car in cars groupedRows=true}} - {{car.make}} {{car.model}} {{car.color}} - {{/each}} - {{/group}} - ``` - Any change to `dealershipName` or the `dealers` collection will cause the - entire group to be re-rendered. However, changes to the `cars` collection - will be re-rendered individually (as normal). - - Note that `group` behavior is also disabled by specifying an `itemViewClass`. - - @method each - @for Ember.Handlebars.helpers - @param [name] {String} name for item (used with `in`) - @param [path] {String} path - @param [options] {Object} Handlebars key/value pairs of options - @param [options.itemViewClass] {String} a path to a view class used for each item - @param [options.itemController] {String} name of a controller to be created for each item - @param [options.groupedRows] {boolean} enable normal item-by-item rendering when inside a `#group` helper - */ - function eachHelper(path, options) { - var ctx, helperName = 'each'; - - if (arguments.length === 4) { - Ember.assert("If you pass more than one argument to the each helper, it must be in the form #each foo in bar", arguments[1] === "in"); - - var keywordName = arguments[0]; - - - options = arguments[3]; - path = arguments[2]; - - helperName += ' ' + keywordName + ' in ' + path; - - if (path === '') { path = "this"; } - - options.hash.keyword = keywordName; - - } else if (arguments.length === 1) { - options = path; - path = 'this'; - } else { - helperName += ' ' + path; - } - - options.hash.dataSourceBinding = path; - // Set up emptyView as a metamorph with no tag - //options.hash.emptyViewClass = Ember._MetamorphView; - - // can't rely on this default behavior when use strict - ctx = this || window; - - options.helperName = options.helperName || helperName; - - if (options.data.insideGroup && !options.hash.groupedRows && !options.hash.itemViewClass) { - new GroupedEach(ctx, path, options).render(); - } else { - // ES6TODO: figure out how to do this without global lookup. - return helpers.collection.call(ctx, 'Ember.Handlebars.EachView', options); - } - } - - __exports__.EachView = EachView; - __exports__.GroupedEach = GroupedEach; - __exports__.eachHelper = eachHelper; - }); -define("ember-handlebars/helpers/loc", - ["ember-runtime/system/string","exports"], - function(__dependency1__, __exports__) { - "use strict"; - var loc = __dependency1__.loc; - - /** - @module ember - @submodule ember-handlebars - */ - - // ES6TODO: - // Pretty sure this can be expressed as - // var locHelper EmberStringUtils.loc ? - - /** - Calls [Ember.String.loc](/api/classes/Ember.String.html#method_loc) with the - provided string. - - This is a convenient way to localize text.
