## Switch 开关
|
||
|
|
|
||
|
|
表示两种相互对立的状态间的切换，多用于触发「开/关」。
|
||
|
|
|
||
|
|
### 基本用法
|
||
|
|
|
||
|
|
:::demo 绑定`v-model`到一个`Boolean`类型的变量。可以使用`active-color`属性与`inactive-color`属性来设置开关的背景色。
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-switch
|
||
|
|
v-model="value"
|
||
|
|
active-color="#13ce66"
|
||
|
|
inactive-color="#ff4949">
|
||
|
|
</el-switch>
|
||
|
|
|
||
|
|
<script>
|
||
|
|
export default {
|
||
|
|
data() {
|
||
|
|
return {
|
||
|
|
value: true
|
||
|
|
}
|
||
|
|
}
|
||
|
|
};
|
||
|
|
</script>
|
||
|
|
```
|
||
|
|

|
||
|
|
|
||
|
|
### 文字描述
|
||
|
|
|
||
|
|
:::demo 使用`active-text`属性与`inactive-text`属性来设置开关的文字描述。
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-switch
|
||
|
|
v-model="value1"
|
||
|
|
active-text="按月付费"
|
||
|
|
inactive-text="按年付费">
|
||
|
|
</el-switch>
|
||
|
|
<el-switch
|
||
|
|
style="display: block"
|
||
|
|
v-model="value2"
|
||
|
|
active-color="#13ce66"
|
||
|
|
inactive-color="#ff4949"
|
||
|
|
active-text="按月付费"
|
||
|
|
inactive-text="按年付费">
|
||
|
|
</el-switch>
|
||
|
|
|
||
|
|
<script>
|
||
|
|
export default {
|
||
|
|
data() {
|
||
|
|
return {
|
||
|
|
value1: true,
|
||
|
|
value2: true
|
||
|
|
}
|
||
|
|
}
|
||
|
|
};
|
||
|
|
</script>
|
||
|
|
```

### 扩展的 value 类型
|
||
|
|
|
||
|
|
:::demo 设置`active-value`和`inactive-value`属性，接受`Boolean`, `String`或`Number`类型的值。
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-tooltip :content="'Switch value: ' + value" placement="top">
|
||
|
|
<el-switch
|
||
|
|
v-model="value"
|
||
|
|
active-color="#13ce66"
|
||
|
|
inactive-color="#ff4949"
|
||
|
|
active-value="100"
|
||
|
|
inactive-value="0">
|
||
|
|
</el-switch>
|
||
|
|
</el-tooltip>
|
||
|
|
|
||
|
|
<script>
|
||
|
|
export default {
|
||
|
|
data() {
|
||
|
|
return {
|
||
|
|
value: '100'
|
||
|
|
}
|
||
|
|
}
|
||
|
|
};
|
||
|
|
</script>

||
|
|
```

### 禁用状态
|
||
|
|
|
||
|
|
:::demo 设置`disabled`属性，接受一个`Boolean`，设置`true`即可禁用。

||
|
|
|
||
|
|
|
||
|
|
```html
|
||
|
|
<el-switch
|
||
