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}} {{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>
效果如如上面展示
