关于el-popover的使用

trigger属性用于设置何时触发 Popover，支持四种触发方式：hover，click，focus 和 manual。

对于触发 Popover 的元素，有两种写法：使用 slot="reference" 的具名插槽，或使用自定义指令v-popover指向 Popover 的索引ref。

<template>
    <div class="listcontent">
      <el-row v-for="(item,index) in datalist" :key="index">
        <el-popover
          placement="right"
          trigger="hover"
        >
            <div class="popup" >
                <h4>{{item.industryName}}</h4>
                <el-row v-for="(zxSysIndustryChildren,cindex) in item.zxSysIndustryChildren" :key="cindex" > 
                    <el-col :span="6" >
                        {{zxSysIndustryChildren.occupationName}}
                    </el-col>

                        <el-radio-group v-model="radio" v-for="(zxSysPositionChildren,tindex) in zxSysIndustryChildren.zxSysPositionChildren" :key="tindex">

方法里面：

            /*取消*/
            cancel(){

            }
