## Tabs 标签页
|
|
|
|
分隔内容上有关联但属于不同类别的数据集合。
|
|
|
|
### 基础用法
|
|
|
|
基础的、简洁的标签页。
|
|
|
|
:::demo Tabs 组件提供了选项卡功能，默认选中第一个标签页，你也可以通过 `value` 属性来指定当前选中的标签页。
|
|
|
|
```html
|
|
<template>
|
|
<el-tabs v-model="activeName" @tab-click="handleClick">
|
|
<el-tab-pane label="用户管理" name="first">用户管理</el-tab-pane>
|
|
<el-tab-pane label="配置管理" name="second">配置管理</el-tab-pane>
|
|
<el-tab-pane label="角色管理" name="third">角色管理</el-tab-pane>
|
|
<el-tab-pane label="定时任务补偿" name="fourth">定时任务补偿</el-tab-pane>
|
|
</el-tabs>
|
|
</template>
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
activeName: 'second'
|
|
};
|
|
},
|
|
methods: {
|
|
handleClick(tab, event) {
|
|
console.log(tab, event);
|
|
}
|
|
}
|
|
};
|
|
</script>
|
|
```
|
|
:::
|
|
|
|
### 选项卡样式
|
|
|
|
选项卡样式的标签页。
|
|
|
|
:::demo 只需要设置 `type` 属性为 `card` 就可以使选项卡改变为标签风格。
|
|
|
|
```html
|
|
<template>
|
|
<el-tabs v-model="activeName2" type="card" @tab-click="handleClick">
|
|
<el-tab-pane label="用户管理" name="first">用户管理</el-tab-pane>
|
|
<el-tab-pane label="配置管理" name="second">配置管理</el-tab-pane>
|
|
<el-tab-pane label="角色管理" name="third">角色管理</el-tab-pane>
|
|
<el-tab-pane label="定时任务补偿" name="fourth">定时任务补偿</el-tab-pane>
|
|
</el-tabs>
|
|
</template>
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
activeName2: 'first'
|
|
};
|
|
},
|
|
methods: {
|
|
handleClick(tab, event) {
|
|
console.log(tab, event);
|
|
}
|
|
}
|
|
};
|
|
</script>
|
|
```
|
|
:::
|
|
|
|
### 卡片化
|
|
|
|
卡片化的标签页。
|
|
|
|
:::demo 将`type`设置为`border-card`。
|
|
```html
|
|
<el-tabs type="border-card">
|
|
<el-tab-pane label="用户管理">用户管理</el-tab-pane>
|
|
<el-tab-pane label="配置管理">配置管理</el-tab-pane>
|
|
<el-tab-pane label="角色管理">角色管理</el-tab-pane>
|
|
<el-tab-pane label="定时任务补偿">定时任务补偿</el-tab-pane>
|
|
</el-tabs>
|
|
```
|
|
:::
|
|
|
|
### 自定义标签页
|
|
|
|
可以通过具名 `slot` 来实现自定义标签页的内容
|
|
|
|
:::demo
|
|
```html
|
|
<el-tabs type="border-card">
|
|
<el-tab-pane>
|
|
<span slot="label"><i class="el-icon-date"></i> 我的行程</span>
|
|
我的行程
|
|
</el-tab-pane>
|
|
<el-tab-pane label="消息中心">消息中心</el-tab-pane>
|
|
<el-tab-pane label="角色管理">角色管理</el-tab-pane>
|
|
<el-tab-pane label="定时任务补偿">定时任务补偿</el-tab-pane>
|
|
</el-tabs>
|
|
```
|
|
:::
|
|
|
|
### 动态增减标签页
|
|
|
|
增减标签页按钮只能在选项卡样式的标签页下使用
|
|
|
|
:::demo
|
|
```html
|
|
<el-tabs v-model="editableTabsValue" type="card" editable @edit="handleTabsEdit">
|
|
<el-tab-pane
|
|
:key="item.name"
|
|
v-for="(item, index) in editableTabs"
|
|
:label="item.title"
|
|
:name="item.name"
|
|
>
|
|
{{item.content}}
|
|
</el-tab-pane>
|
|
</el-tabs>
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
editableTabsValue: '2',
|
|
editableTabs: [{
|
|
title: 'Tab 1',
|
|
name: '1',
|
|
content: 'Tab 1 content'
|
|
}, {
|
|
title: 'Tab 2',
|
|
name: '2',
|
|
content: 'Tab 2 content'
|
|
}],
|
|
tabIndex: 2
|
|
}
|
|
},
|
|
methods: {
|
|
handleTabsEdit(targetName, action) {
|
|
if (action === 'add') {
|
|
let newTabName = ++this.tabIndex + '';
|
|
this.editableTabs.push({
|
|
title: 'New Tab',
|
|
name: newTabName,
|
|
content: 'New Tab content'
|
|
});
|
|
this.editableTabsValue = newTabName;
|
|
}
|
|
if (action === 'remove') {
|
|
let tabs = this.editableTabs;
|
|
let activeName = this.editableTabsValue;
|
|
if (activeName === targetName) {
|
|
tabs.forEach((tab, index) => {
|
|
if (tab.name === targetName) {
|
|
let nextTab = tabs[index + 1] || tabs[index - 1];
|
|
if (nextTab) {
|
|
activeName = nextTab.name;
|
|
}
|
|
}
|
|
});
|
|
}
|
|
|
|
this.editableTabsValue = activeName;
|
|
this.editableTabs = tabs.filter(tab => tab.name !== targetName);
|
|
}
|
|
}
|
|
}
|
