## Loading

Show animation while loading data.

### Loading inside a container

Displays animation in a container (such as a table) while loading data.

:::demo We provide a custom directive `v-loading`. You just need to bind a `boolean` value to it. By default, the loading mask will append to the element where the directive is used. Adding the `body` modifier makes the mask append to the body element.

```html
<template>
  <el-table
    v-loading.body="loading"
    :data="tableData"
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-02',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }, {
          date: '2016-05-04',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }, {
          date: '2016-05-01',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }],
        loading: true
      };
    }
  };
</script>
```
:::

### Loading text

You can customize a text message.

:::demo
```html
<template>
  <el-table
    v-loading="loading2"
    element-loading-text="Loading..."
    :data="tableData"
    style="width: 100%">
    <el-table-column
      prop="date"
      label="Date"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="Name"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="Address">
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-02',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }, {
          date: '2016-05-04',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }, {
          date: '2016-05-01',
          name: 'John Smith',
          address: 'No.1518,  Jinshajiang Road, Putuo District'
        }],
        loading2: true
      };
    }
  };
</script>
```
:::

### Full screen loading

Show a full screen animation while loading data.  

:::demo Add the `fullscreen` modifier to create a full screen mask, and it will append to body. In this case, if you disable scrolling on body, you add another modifier `lock`.

```html
<template>
  <el-button
    type="primary"
    @click.native="openFullScreen"
    v-loading.fullscreen.lock="fullscreenLoading">
    Full screen loading for 3 seconds
  </el-button>
</template>

<script>
  export default {
    data() {
      return {
        fullscreenLoading: false
      }
    },
    methods: {
      openFullScreen() {
        this.fullscreenLoading = true;
        setTimeout(() => {
          this.fullscreenLoading = false;
        }, 3000);
      }
    }
  }
</script>
```
