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>

1-1-1 routers/home/index.vue

<template>
 <div>

   <router-link :to="{name: 'rindex_rhome_rhomegn'}" class="rlink" :class="{active:selected == 3}" @click.native="tabck(3)">国内home</router-link>
  
  <!-- 子路由(三层) -->
   <router-view />
 </div>
</template>
<script>
 export default {
  data(){
    return {
      selected: 1

2.路由配置规则(router/index.js)

....
 省略导入路由、使用路由代码...
....
// 嵌套路由的使用：第一层
import rindex from '../page/routers/index'
// 嵌套路由的使用：第二层
import rhome from '../page/routers/home/index'
// 嵌套路由的使用：第三层
import rhomezx from '../page/routers/home/tab/zx'
import rhomegj from '../page/routers/home/tab/gj'

// 路由规则配置：
export default new router({
 routes : [

       path: 'rindex_rhome', //如果这里不使用 "/rhome" 则表示是归属于上级路由（上级luyou/子path），如果使用 "/rhome" 则表示根路径下访问
       component: rhome,
       redirect: {name: 'rindex_rhome_rhomezx'}, //跳转到下级第一层
