## 基础用法
2016-08-19 14:45:08 +08:00
Popover 的属性与 Tooltip 很类似,它们都是基于`Vue-popper`开发的,因此对于重复属性,请参考 Tooltip 的文档,在此文档中不做详尽解释。
要使用它,必须设置索引`ref`,在按钮中,我们注册了自定义指令`v-popover`指向索引ID。
`trigger`属性用于设置何时触发 Popover ,提供三种触发方式:`hover`, `click``focus`,下面是样例,一些没有做解释的属性是与 Tooltip 一致的。

<div class="demo-box demo-popover">
<el-popover
2016-08-05 17:02:01 +08:00

2016-07-27 14:15:02 +08:00
</div>
```html
<el-popover
2016-08-05 17:02:01 +08:00
ref="popover1"
2016-07-27 14:15:02 +08:00
placement="top-start"

## 嵌套信息
2016-08-19 14:45:08 +08:00
和其他组件一样Popover 组件也可以利用分发取代`content`属性,下面我们嵌套了一个表格:
2016-07-27 14:15:02 +08:00
<div class="demo-box demo-popover">
<el-popover
2016-08-05 17:02:01 +08:00
ref="popover4"
2016-07-27 14:15:02 +08:00
placement="right"
width="400"
trigger="click">
<el-table :data="gridData">
<el-table-column width="150" property="date" label="日期"></el-table-column>
<el-table-column width="100" property="name" label="姓名"></el-table-column>
<el-table-column width="300" property="address" label="地址"></el-table-column>
</el-table>
</el-popover>
<el-button v-popover:popover4>click 激活</el-button>
</div>
```html
<el-popover
2016-08-05 17:02:01 +08:00
ref="popover4"
2016-07-27 14:15:02 +08:00
placement="right"
width="400"
trigger="click">
<el-table :data="gridData">
<el-table-column width="150" property="date" label="日期"></el-table-column>
<el-table-column width="100" property="name" label="姓名"></el-table-column>
<el-table-column width="300" property="address" label="地址"></el-table-column>
</el-table>
</el-popover>
<el-button v-popover:popover4>click 激活</el-button>
```
## 嵌套操作
2016-08-19 14:45:08 +08:00
当然,你还可以嵌套操作,这相比 Dialog 更为轻量:
2016-07-27 14:15:02 +08:00
<div class="demo-box demo-popover">
<el-popover
2016-08-05 17:02:01 +08:00
ref="popover5"
2016-07-27 14:15:02 +08:00
placement="top"
width="160"
:visible.sync="visible2">
<p>这是一段内容这是一段内容确定删除吗?</p>
<div style="text-align: right; margin: 0">
2016-08-19 14:45:08 +08:00
<el-button size="mini" type="text" @click="visible2 = false">取消</el-button>
<el-button type="primary" size="mini" @click="visible2 = false">确定</el-button>
2016-07-27 14:15:02 +08:00
</div>
</el-popover>
<el-button v-popover:popover5>删除</el-button>
</div>
```html
<el-popover
2016-08-05 17:02:01 +08:00
ref="popover5"
2016-07-27 14:15:02 +08:00
placement="top"
width="160"
:visible.sync="visible2">
<p>这是一段内容这是一段内容确定删除吗?</p>
<div style="text-align: right; margin: 0">
2016-08-19 14:45:08 +08:00
<el-button size="mini" type="text" @click="visible2 = false">取消</el-button>
<el-button type="primary" size="mini" @click="visible2 = false">确定</el-button>
2016-07-27 14:15:02 +08:00
</div>
</el-popover>
<el-button v-popover:popover5>删除</el-button>
```
