路由嵌套

在上一代码的基础上 ：
创建 views.user.Profile.vue:

<template>
    <h1>个人信息</h1>
</template>

<script>
    export default {
        name: "UserProfile"
    }
</script>

<style scoped>

</style>

创建 views.user.List.vue:

<template>
    <h1>用户列表</h1>
</template>

<script>
    export default {
        name: "UserList"
    }
</script>

<style scoped>

</style>

Main.vue:

<template>
  <el-container style="height: 500px; border: 1px solid #eee">
    <el-aside width="200px" style="background-color: rgb(238, 241, 246)">
      <el-menu :default-openeds="['1']">
        <el-submenu index="1">
          <template slot="title">
            <i class="el-icon-message"></i>用户管理
          </template>
          <el-menu-item-group>
            <el-menu-item index="1-1">
              <router-link to="/user/profile">个人信息</router-link>
            </el-menu-item>

            <el-menu-item index="1-2">
              <router-link to="/user/list">用户列表</router-link>
            </el-menu-item>
          </el-menu-item-group>
        </el-submenu>
        <el-submenu index="2">
          <template slot="title">
            <i class="el-icon-menu"></i>内容管理
          </template>
          <el-menu-item-group>
            <el-menu-item index="2-1">分类管理</el-menu-item>
            <el-menu-item index="2-2">内容列表</el-menu-item>
          </el-menu-item-group>
        </el-submenu>

      </el-menu>
    </el-aside>

    <el-container>
      <el-header style="text-align: right; font-size: 12px">
        <el-dropdown>
          <i class="el-icon-setting" style="margin-right: 15px"></i>
          <el-dropdown-menu slot="dropdown">
            <el-dropdown-item>个人信息</el-dropdown-item>
            <el-dropdown-item>退出登录</el-dropdown-item>
          </el-dropdown-menu>
        </el-dropdown>
      </el-header>

      <el-main>
        <router-view/>
      </el-main>
    </el-container>
  </el-container>
</template>

<style>
  .el-header {
    background-color: #b3c0d1;
    color: #333;
    line-height: 60px;
  }

  .el-aside {
    color: #333;
  }
</style>

<script>
  export default {
    data() {
      const item = {
        date: "2016-05-02",
        name: "王小虎",
        address: "上海市普陀区金沙江路 1518 弄"
      };
      return {
        tableData: Array(20).fill(item)
      };
    }
  };
</script>

在Main路由中嵌套UserProfile和UserList
index.js:

import Vue from 'vue'
import Router from 'vue-router'

import Main from "../views/Main";
import Login from "../views/Login";
import UserList from "../views/user/List"
import UserProfile from "../views/user/Profile"


Vue.use(Router);

export default new Router({
  routes: [
    {
      path: '/main',
      component: Main,
      //嵌套路由
      children: [
        {path: '/user/profile',component: UserProfile},
        {path: '/user/list',component: UserList},
      ]
    },
    {
      path: '/login',
      component: Login
    }
  ]
});
