首先需要引入Vue.js!!!!!      直接上代码 
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="../static/vue.js"></script>
    <style>
        ul{
            background-color: aqua;
        }
 
        .zg{
            background-color: magenta;
        }
    </style>
 
</head>
<body>
 
<div align="center" id="chd">
    <ul v-for="(item,index) in aaa" @click="bbb(item,index)" v-bind:class="{zg:number === index}">
        <li>{{index}}&nbsp;&nbsp;{{item}}</li>
    </ul>
<hr>
<h3>选择了:{{se}}</h3>
    <script>
        var  aaa= new Vue({
            el:"#chd",
            data:{
                aaa:['蔡徐坤','陈厚德','小熊','大熊'],
                se:"",
                number:0
            },
            methods:{
                bbb:function (item,index){
                    this.se=item;
                    this.number=index;
                }
            }
        })
    </script>
</div>
</body>
</html>
