VUE的for循环

<ul>
     <li v-for="(aff , index) in acc" :key="index">编号：{{aff.a}}
       <div>名字：{{aff.name}}</div>
       <div>年龄：{{aff.age}}</div>
     </li>
 </ul>


<script>
  data () {
    return {
      acc:[
        {a:'3544', name:'小米', age:50},
        {a:'3543', name:'中米', age:51},
        {a:'3542', name:'大米', age:52},
        {a:'3541', name:'超大米', age:53}
      ]
    }    
  }
</script>

v-for="(变量名,下标名) in 目标数组" :key="下标名"  相当于for循环在页面直接输出
