</body>
</html>

ps:下面看下vue-elementUI 弹出框

<div class="dial-header">
   <el-dialog title="请选择适配器" :visible.sync="showFlag" style="width:900px">
   <div style="text-align: left; margin: 0;width:400px;" >
    <div class="adp" v-for="adapter in adapters" style="width:300px;height:30px;line-height:30px;border-top:none;margin:0px 0px 0px 40px">
    <el-radio :label="adapter.ip" style="width:200px;padding-left:40px" v-model="radio"></el-radio>
    <div style="display: inline-block;width:30px"><img v-if="!adapter.val" src="../../static/images/grey.png"><img v-if="adapter.val" src="../../static/images/green.png"></div>
    </div>
    <div style="padding-top:20px;text-align: right">
    <el-button type="text" size="small" @click="showFlag = false">取消</el-button>
    <el-button type="primary" size="small" @click="radioEvent()">确定</el-button>
    </div>
   </div>
   </el-dialog>
   <el-button type="primary" @click="showFlag = true">选择</el-button>
  </div>
 <script>
 export default {
  data () {
  return {
   showFlag: false,
   radio:""
  }
  },
  methods:{
  radioEvent(){
   this.showFlag = false;
   this.adapterSelected = this.radio;
  },
 }
 </script>
