||
## 基本用法
|
||
|
||
:::demo 在 Loading 组件中，Element 准备了自定义命令`v-loading`，只需要绑定`Boolean`即可，默认状况下，Loading 遮罩会插入到绑定元素的子节点。
|
||
|
||
```html
|
||
<el-button :plain="true" @click.native="loading = !loading">打开 / 关闭 loading</el-button>
|
||
|
||
<div v-loading="loading" class="el-loading-demo">
|
||
<p>点击上面的按钮，本区域显示 loading 遮罩</p>
|
||
</div>
|
||
```
|
||
:::
|
||
|
||
## 修饰符
|
||
|
||
通过修饰符，我们可以使用全屏幕 Loading 或将 Loading 设置在 body 上。
|
||
|
||
:::demo Loading 遮罩默认插入至绑定了 `v-loading` 指令的元素上。通过添加 `body` 修饰符，可以使遮罩插入至 DOM 中的 body 上。当需要全屏遮罩时，可使用 `fullscreen` 修饰符（此时遮罩会插入至 body 上）
|
||
|
||
```html
|
||
<template>
|
||
<el-button :plain="true" @click.native="loading2 = !loading2">打开 / 关闭 loading</el-button>
|
||
|
||
<el-button
|
||
:plain="true"
|
||
@click.native="openFullScreen"
|
||
v-loading.fullscreen="fullscreenLoading">
|
||
打开全屏 loading
|
||
</el-button>
|
||
|
||
<div v-loading.body="loading2" class="el-loading-demo">
|
||
<p>点击上面的按钮，本区域显示 loading 遮罩</p>
|
||
</div>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
fullscreenLoading: false
|
||
}
|
||
}
|
||
methods: {
|
||
openFullScreen() {
|
||
this.fullscreenLoading = true;
|
||
setTimeout(() => {
|
||
this.fullscreenLoading = false;
|
||
}, 2000);
|
||
}
|
||
}
|
||
}
|
||
</script>
|

```
