## 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`on-text`属性与`off-text`属性来设置开关的文字描述，使用`on-color`属性与`off-color`属性来设置开关的背景色。
|
||
|
||
```html
|
||
<el-switch
|
||
v-model="value1"
|
||
on-text=""
|
||
off-text="">
|
||
</el-switch>
|
||
<el-switch
|
||
v-model="value2"
|
||
on-color="#13ce66"
|
||
off-color="#ff4949">
|
||
</el-switch>
|
||
</el-switch>
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
value1: true,
|
||
value2: true
|
||
}
|
||
}
|
||
};
|
||
</script>
|
||
```
|
||
:::
|
||
|
||
### 扩展的 value 类型
|
||
|
||
:::demo 设置`on-value`和`off-value`属性，接受`Boolean`, `String`或`Number`类型的值。
|
||
|
||
```html
|
||
<el-tooltip :content="'Switch value: ' + value3" placement="top">
|
||
<el-switch
|
||
v-model="value3"
|
||
on-color="#13ce66"
|
||
off-color="#ff4949"
|
||
on-value="100"
|
||
off-value="0">
|
||
</el-switch>
|
||
</el-tooltip>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
value3: '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
|
||
v-model="value4"
|
||
on-text=""
|
||
off-text=""
|
||
disabled>
|
||
</el-switch>
|
||
<el-switch
|
||
v-model="value4"
|
||
disabled>
|
||
</el-switch>
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
value4: true
|
||
}
|
||
}
|
||
};
|
||
</script>
|
||
```
