1、使用index
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>vue导航</title>
<style media="screen">
*{
margin:0;
padding: 0;
}
ul li{
list-style: none;
}
.navul{
margin:100px auto 20px;
overflow: hidden;
}
.navul li{
background-color: #5597b4;
padding:18px 30px;
float:left;
color: #fff;
font-size: 18px;
cursor: pointer;
}
.active{
background-color: #5597b4;
}
.home .home,.new .new,.contact .contact,.service .service{
background-color: skyblue;
}
.checked{
background: #eff4f7;
}
</style>
</head>
<body>
<div id="nav">
<ul>
<li v-for="(relation,index) in relations" v-bind:id="relation.id" v-bind:id="relation.id" v-bind:class="{checked:index==nowIndex}" v-on:click="relationClick(index)">
<i></i>
<span class="">{{relation.text}}</span>
</li>
</ul>
</div>
<script src="/UploadFiles/2021-04-02/vue.js">
2、通过改变当前值切换类名
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>点击切换</title>
<style>
.glyphicon-minus{
color:#08f;
}
.glyphicon-plus{
color:purple;
}
</style>
<script src="/UploadFiles/2021-04-02/vue.js">拓展知识：vue点击改变样式的实例
data里

method里
checkedItem(index){

},
页面里
<div v-for="(item,index) in nameoptions" v-bind:class="{active:index==isActive}" @click="checkItem(index)>{{item.name}}</div>
