<div class="ticket-main">
     <a href="javascript:void(0);" rel="external nofollow" class="weui_media_box weui_media_appmsg weui_media_box_bg" v-for="item in mediaBox" :date-id="item.num" v-on:click="upHref($event)">
       <div class="weui_media_hd">
         <img class="weui_media_appmsg_thumb" :src="/UploadFiles/2021-04-02/item.mediaBoxImg">

三、js代码


var secretRecipe = new Vue({
  el: "#secret-recipe",
  data: {
    pointsNum: [],
    mediaBox:[]
  },
  methods:{
    upHref:function(e){
      hrefSrc(e.currentTarget);
    }
  }
});
var prize=[
  {mediaBoxImg:"../b2b-reception/images/secret/icon_01.png",name:"双色球彩票一注",price:'250',num:"1"},
  {mediaBoxImg:"../b2b-reception/images/secret/icon_02.png",name:"50M流量",price:'230',num:"2"},
  {mediaBoxImg:"../b2b-reception/images/secret/icon_03.png",name:"景点抽抽乐",price:"300",num:"3"}
  ];
$(function(){  
  secretRecipe.mediaBox = prize;  
})

function hrefSrc(v){
  console.log($(v).attr("date-id"));
  $.modal({
    title: "支付方式",
    text: "选择你的支付方式",
    buttons: [
     { text: "转化积分", onClick: function(){ $.alert("你选择了转化积分"); } },
     { text: "立即购买", onClick: function(){ $.alert("你选择了立即购买"); } },
     { text: "取消", className: "default"},
    ]
   });
}



重点说明：$event，官方文档中是说该对象【在监听原生 DOM 事件时，方法以事件为唯一的参数。如果使用内联语句，语句可以访问一个 $event 属性：v-on:click="handle('ok', $event)"。】

handle(e){e.currentTarget}

方法接收时取的是点击的该DOM本身

handle(e){e.target}

方法接收时取的是点击的该元素

handle(e){e.target.tagName}

方法接收时取的是点击的该元素的标签名(如div.p.img)
补充知识：VUE之命令行报错：Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead 解决办法

Failed to compile.

- Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead.

<template>
 <div><el-header class="animated faedOutUp"><myHeader></myHeader></el-header></div>

修改后如下


<template>
 <div>
  <el-header class="animated faedOutUp"><myHeader></myHeader></el-header>
  <div>这里才是首页</div>
 </div>
</template>


保存运行，错误解决了！
