<script>
  module.exports = {
    data() {
      return {
        checkList: ['选中且禁用','复选框 A'],
        // checkList2: ['复选框 A'],
        checked: true,
        name: 'Jonny',
        a: 'Jonny',
        b: 'Lara'
      };
    }
  };
</script>


<style>
  .demo-box.demo-checkbox {
    .checkbox {
      margin-right: 5px;

      & + .checkbox {
        margin-left: 10px;
      }
    }
  }
</style>

## 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 class="checkbox" v-model="checkList" label="复选框 A"></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="复选框 B"></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="复选框 C"></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="禁用" disabled></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="选中且禁用" disabled></el-checkbox>
</div>

<p>{{ checkList }}</p>

```html
<template>
  <el-checkbox class="checkbox" v-model="checkList" label="复选框 A"></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="复选框 B"></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="复选框 C"></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="禁用" disabled></el-checkbox>
  <el-checkbox class="checkbox" v-model="checkList" label="选中且禁用" disabled></el-checkbox>
</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
```
