## Dialog 对话框
|
||
在保留当前页面状态的情况下，告知用户并承载相关操作。
|
||
|
||
### 基本用法
|
||
|
||
Dialog 弹出一个对话框，适合需要定制性更大的场景。
|
||
|
||
:::demo 需要设置`v-model`属性，它接收`Boolean`，当为`true`时显示 Dialog。Dialog 分为两个部分：`body`和`footer`，`footer`需要具名为`footer`的`slot`。`title`属性用于定义标题，它是可选的，默认值为空。本例通过显式改变`v-model`的值来打开 Dialog，此外我们还为 Dialog 实例提供了`open`和`close`方法，可以通过调用它们来打开/关闭 Dialog。
|
||
|
||
```html
|
||
<el-button type="text" @click="dialogVisible = true">点击打开 Dialog</el-button>
|
||
|
||
<el-dialog title="提示" v-model="dialogVisible" size="tiny">
|
||
<span>这是一段信息</span>
|
||
<span slot="footer" class="dialog-footer">
|
||
<el-button @click="dialogVisible = false">取 消</el-button>
|
||
<el-button type="primary" @click="dialogVisible = false">确 定</el-button>
|
||
</span>
|
||
</el-dialog>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
dialogVisible: false
|
||
};
|
||
}
|
||
};
|
||
</script>
|
||
```
|
||

||
### 自定义内容
|
||
|
||
Dialog 组件的内容可以是任意的，甚至可以是表格或表单，下面是应用了 Element Table 和 Form 组件的两个样例。
|
||
|
||
:::demo
|
||
```html
|
||
<!-- Table -->
|
||
<el-button type="text" @click="dialogTableVisible = true">打开嵌套表格的 Dialog</el-button>
|
||
|
||
<el-dialog title="收货地址" v-model="dialogTableVisible">
|
||
<el-table :data="gridData">
|
||
<el-table-column property="date" label="日期" width="150"></el-table-column>
|
||
<el-table-column property="name" label="姓名" width="200"></el-table-column>
|
||
<el-table-column property="address" label="地址"></el-table-column>
|
||
</el-table>
|
||
</el-dialog>
|
||
|
||
<!-- Form -->
|
||
<el-button type="text" @click="dialogFormVisible = true">打开嵌套表单的 Dialog</el-button>
|
||
|
||
<el-dialog title="收货地址" v-model="dialogFormVisible">
|
||
<el-form :model="form">
|
||
<el-form-item label="活动名称" :label-width="formLabelWidth">
|
||
<el-input v-model="form.name" auto-complete="off"></el-input>
|
||
</el-form-item>
|
||
<el-form-item label="活动区域" :label-width="formLabelWidth">
|
||
<el-select v-model="form.region" placeholder="请选择活动区域">
|
||
<el-option label="区域一" value="shanghai"></el-option>
|
||
<el-option label="区域二" value="beijing"></el-option>
|
||
</el-select>
|
||
</el-form-item>
|
||
</el-form>
|
||
<div slot="footer" class="dialog-footer">
|
||
<el-button @click="dialogFormVisible = false">取 消</el-button>
|
||
<el-button type="primary" @click="dialogFormVisible = false">确 定</el-button>
|
||
</div>
|
||
</el-dialog>
|
||
|
||

|
