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>
