module.exports = {
|
||
data() {
|
||
return {
|
||
checkList: ['选中且禁用','复选框 A'],
|
||
// checkList2: ['复选框 A'],
|
||
checked: true,
|
||
name: 'Jonny',
|

## 基础用法
|
||
|
||
### 单个勾选框，逻辑值
|
||
|
||
<div class="demo-box demo-checkbox">
|
||
<el-checkbox class="checkbox" v-model="checked">{{ checked }}</el-checkbox>
|
||
</div>
|
||
|
||
```html
|
||
<el-checkbox class="checkbox" v-model="checked">{{ checked }}</el-checkbox>
|
||
```
|
||
|
||
### 多个勾选框，绑定到同一个数组
|
||
|
||
<div class="demo-box demo-checkbox">
|
||
<el-checkbox-group v-model="checkList">
|
||
<el-checkbox class="checkbox" label="复选框 A"></el-checkbox>
|
||
<el-checkbox class="checkbox" label="复选框 B"></el-checkbox>
|
||
<el-checkbox class="checkbox" label="复选框 C"></el-checkbox>
|
||
<el-checkbox class="checkbox" label="禁用" disabled></el-checkbox>
|
||
<el-checkbox class="checkbox" label="选中且禁用" disabled></el-checkbox>
|
||
</el-checkbox-group>
|
||
</div>
|
||
|
||
<p>{{ checkList }}</p>
|
||
|
||
```html
|
||
<template>
|
||
<el-checkbox-group v-model="checkList">
|
||
<el-checkbox class="checkbox" label="复选框 A"></el-checkbox>
|
||
<el-checkbox class="checkbox" label="复选框 B"></el-checkbox>
|
||
<el-checkbox class="checkbox" label="复选框 C"></el-checkbox>
|
||
<el-checkbox class="checkbox" label="禁用" disabled></el-checkbox>
|
||
<el-checkbox class="checkbox" label="选中且禁用" disabled></el-checkbox>
|
||
</el-checkbox-group>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data () {
|
||
return {
|
||
checkList: ['选中且禁用','复选框 A']
|
||
}
|
||
}
|
||
}
|
||
</script>
|
||
```
|
||
|
||
### 绑定 value：
|
||
|
||
<div class="demo-box demo-checkbox">
|
||
<el-checkbox
|
||
class="checkbox"
|
||
v-model="name"
|
||
:true-label="a"
|
||
:false-label="b">
|
||
{{name}}
|
||
</el-checkbox>
|
||
</div>
|
||
|
||
```html
|
||
<el-checkbox
|
||
class="checkbox"
|
||
v-model="name"
|
||
:true-label="a"
|
||
:false-label="b">
|
||
{{name}}
|
||
</el-checkbox>
|
||
```
|
||
|
||
```js
|
||
vm.a = 'Jonny';
|
||
vm.b = 'Lara';
|
||
// 当选中时
|
||
vm.name === vm.a
|
||
// 当没有选中时
|
||
vm.name === vm.b
|
||
```
