## Popover
|
|
|
|
### Uso básico
|
|
|
|
Similar a un Tooltip, Popover está construido con `Vue-popper`. Así que para atributos duplicados, por favor refiérase a la documentación de Tooltip.
|
|
|
|
:::demo El atributo `trigger` es usado para definir como el popover se dispara: `hover`, `click`, `focus` o `manual`. En cuanto al elemento desencadenante, puedes escribirlo de dos maneras diferentes: usando el `slot="reference"`[named slot](https://vuejs.org/v2/guide/components.html#Named-Slots), o usando la directiva `v-popover` y poniendo el `ref` de Popover.
|
|
|
|
```html
|
|
<template>
|
|
<el-popover
|
|
placement="top-start"
|
|
title="Title"
|
|
width="200"
|
|
trigger="hover"
|
|
content="this is content, this is content, this is content">
|
|
<el-button slot="reference">Hover to activate</el-button>
|
|
</el-popover>
|
|
|
|
<el-popover
|
|
placement="bottom"
|
|
title="Title"
|
|
width="200"
|
|
trigger="click"
|
|
content="this is content, this is content, this is content">
|
|
<el-button slot="reference">Click to activate</el-button>
|
|
</el-popover>
|
|
|
|
<el-popover
|
|
ref="popover"
|
|
placement="right"
|
|
title="Title"
|
|
width="200"
|
|
trigger="focus"
|
|
content="this is content, this is content, this is content">
|
|
</el-popover>
|
|
<el-button v-popover:popover>Focus to activate</el-button>
|
|
|
|
<el-popover
|
|
placement="bottom"
|
|
title="Title"
|
|
width="200"
|
|
trigger="manual"
|
|
content="this is content, this is content, this is content"
|
|
v-model="visible">
|
|
<el-button slot="reference" @click="visible = !visible">Manual to activate</el-button>
|
|
</el-popover>
|
|
</template>
|
|
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
visible: false
|
|
};
|
|
}
|
|
};
|
|
</script>
|
|
```

|
### Información anidada
|
|
Otros componentes pueden anidarse dentro de popover. A continuación un ejemplo de una tabla anidada.
|
|
|
|
:::demo Reemplaza el atributo `content` con un `slot`.
|
|
|
|
```html
|
|
<el-popover
|
|
placement="right"
|
|
width="400"
|
|
trigger="click">
|
|
<el-table :data="gridData">
|
|
<el-table-column width="150" property="date" label="date"></el-table-column>
|
|
<el-table-column width="100" property="name" label="name"></el-table-column>
|
|
<el-table-column width="300" property="address" label="address"></el-table-column>
|
|
</el-table>
|
|
<el-button slot="reference">Click to activate</el-button>
|
|
</el-popover>
|
|
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
gridData: [{
|
|
date: '2016-05-02',
|
|
name: 'Jack',
|
|
address: 'New York City'
|
|
}, {
|
|
date: '2016-05-04',
|
|
name: 'Jack',
|
|
address: 'New York City'
|
|
}, {
|
|
date: '2016-05-01',
|
|
name: 'Jack',
|
|
address: 'New York City'
|
|
}, {
|
|
date: '2016-05-03',
|
|
name: 'Jack',
|
|
address: 'New York City'
|
|
}]
|
|
};
|
|
}
|
|
};
|
|
</script>
|
|
```
|
|
:::
|
|
|
|
### Operación anidada
|
|
|
|
Por supuesto, puedes anidar otras operaciones. Es más ligero que utilizar un `dialog`.
|
|
|
|
:::demo
|
|
```html
|
|
<el-popover
|
|
placement="top"
|
|
width="160"
|
|
v-model="visible">
|
|
<p>Are you sure to delete this?</p>
|
|
<div style="text-align: right; margin: 0">
|
|
<el-button size="mini" type="text" @click="visible = false">cancel</el-button>
|
|
<el-button type="primary" size="mini" @click="visible = false">confirm</el-button>
|
|
</div>
|
|
<el-button slot="reference">Delete</el-button>
|
|
</el-popover>
|
|
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
visible: false,
|
|
};
|
|
}
|
|
}
|
|
</script>
|
|
```
