Vue三层嵌套路由的示例代码

Vue嵌套路由：

实现效果(路由三层嵌套，点击一级tab显示二级tab效果，二级tab点击切换对应内容,不在tab区域里的内容，切换时不重复渲染)：

Demo访问时路径：http://IP:端口/#/routers/

1.建立案例文件夹 page/routers/

1 routers/index.vue

<template>
 <div>
 <router-link :to="{name: 'rindex_rhome'}" class="rlink" :class="{active:selected == 1}" @click.native="tabck(1)">首页</router-link>
 <router-link :to="{name: 'rindex_rnews'}" class="rlink" class="{active:selected == 2}" @click.native="tabck(2)">新闻</router-link>
 <router-link :to="{name: 'rindex_ryl'}" class="rlink" class="{active:selected == 3}" @click.native="tabck(3)">娱乐</router-link>
 
 <!-- 二级子路由页面 -->
 <router-view />
 </div>
</template>
<script>
export default {
 data(){
 return {
 selected: 1
 }
 },
 methods: {
 tabck(index){
 this.selected = index; //设置tab选中项
 }
 }
}
</script>
<style>
 .rlink {
 padding: 5px;
 margin: 5px;
 margin-bottom: 10px;
 display: inline-block;
 text-decoration: none;
 color: blue;
 }

 .rlink.active {
 color: red;
 text-decoration: underline;
 }
</style>

2.路由配置规则(router/index.js)

....
 省略导入路由、使用路由代码...
