How to use Vue three-layer nested routing

This time I will show you how to use Vue three-layer nested routing, and what are the precautions when using Vue three-layer nested routing. The following is a practical case, let's take a look.

Vue nested routing:

Achieve the effect (the routing is nested at three levels, click on the first-level tab to display the second-level tab effect, click on the second-level tab to switch the corresponding content, Content not in the tab area will not be rendered repeatedly when switching):

1. Create the case folder page/routers/

1 routers/index.vue

<template>
 <p>
   <router-link>首页</router-link>
   <router-link>新闻</router-link>
   <router-link>娱乐</router-link>
  
    <!-- 二级子路由页面 -->
    <router-view></router-view>
 </p>
</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>
