Vue 嵌套路由

1.创建Main.vue,主页面带有侧边栏

<template>
  <div class="app">
    <el-container>
      <el-aside class="app-side app-side-left"
                :class="isCollapse ? 'app-side-collapsed' : 'app-side-expanded'">
        <div class="app-side-logo">
          <img src="@/assets/logo.png"
               :width="isCollapse ? '60' : '60'"
               height="60" />
        </div>
        <div>
          <!-- 我是样例菜单 -->
          <el-menu default-active="1-4-1"
                   class="el-menu-vertical-demo"
                   @open="handleOpen"
                   :collapse="isCollapse">
            <el-submenu index="1">
              <template slot="title">
                <i class="el-icon-location"></i>
                <span slot="title">系统维护</span>
              </template>
              <el-menu-item-group>
                <span slot="title">分组一</span>
                <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-menu-item-group title="分组2">
                <el-menu-item index="1-3">选项3</el-menu-item>
              </el-menu-item-group>
              <el-submenu index="1-4">
                <span slot="title">选项4</span>
                <el-menu-item index="1-4-1">选项1</el-menu-item>
              </el-submenu>
            </el-submenu>
            <el-menu-item index="2">
              <i class="el-icon-menu"></i>
              <span slot="title">导航二</span>
            </el-menu-item>
            <el-menu-item index="3"
                          disabled>
              <i class="el-icon-document"></i>
              <span slot="title">导航三</span>
            </el-menu-item>
            <el-menu-item index="4">
              <i class="el-icon-setting"></i>
              <span slot="title">导航四</span>
            </el-menu-item>
          </el-menu>
        </div>
      </el-aside>

      <el-container>
        <el-header class="app-header">
          <div style="width: 60px; cursor: pointer;"
               @click.prevent="toggleSideBar">
            <i v-show="!isCollapse" class="el-icon-d-arrow-left"></i>
            <i v-show="isCollapse" class="el-icon-d-arrow-right"></i>
          </div>
          <!-- 我是样例菜单 -->
          <el-menu default-active="1"
                   class="el-menu-demo tab-page"
                   mode="horizontal"
                   @select="handleSelect"
                   active-text-color="#409EFF">
            <el-menu-item index="1">处理中心</el-menu-item>
            <el-submenu index="2">
              <template slot="title">我的工作台</template>
              <el-menu-item index="2-1">选项1</el-menu-item>
              <el-menu-item index="2-2">选项2</el-menu-item>
              <el-menu-item index="2-3">选项3</el-menu-item>
              <el-submenu index="2-4">
                <template slot="title">选项4</template>
                <el-menu-item index="2-4-1">选项1</el-menu-item>
                <el-menu-item index="2-4-2">选项2</el-menu-item>
                <el-menu-item index="2-4-3">选项3</el-menu-item>
              </el-submenu>
            </el-submenu>
            <el-menu-item index="3"
                          disabled>消息中心</el-menu-item>
            <el-menu-item index="4">
              <a href="#">订单管理</a>
            </el-menu-item>
          </el-menu>

          <div class="app-header-userinfo">
            <el-dropdown trigger="hover"
                         :hide-on-click="false">
              <span class="el-dropdown-link">
                {{ username }}
                <i class="el-icon-arrow-down el-icon--right"></i>
              </span>
              <el-dropdown-menu slot="dropdown">
                <el-dropdown-item>我的消息</el-dropdown-item>
                <el-dropdown-item>设置</el-dropdown-item>
                <el-dropdown-item divided
                                  @click.native="logout">退出登录</el-dropdown-item>
              </el-dropdown-menu>
            </el-dropdown>
          </div>
        </el-header>

        <el-main class="app-body">
          <template>
            <router-view/>
          </template>
        </el-main>
      </el-container>
    </el-container>
  </div>
</template>

<script>
  export default {
    name: 'Container',
    data() {
      return {
        username: '',
        isCollapse: false
      }
    },
    methods: {
      toggleSideBar() {
        this.isCollapse = !this.isCollapse
      },
      logout: function () {
        this.$confirm('确认退出?', '提示', {})
          .then(() => {
            sessionStorage.removeItem('user');
            this.$router.push('/login');
          })
          .catch(() => { });
      },
      handleOpen(key, keyPath) {
        console.log(key, keyPath);
      },
      handleClose(key, keyPath) {
        console.log(key, keyPath);
      },
      handleSelect(key, keyPath) {
        console.log(key, keyPath);
      },
    },
    mounted: function () {
      let user = sessionStorage.getItem('user');
      if (user) {
        this.username = user;
      }
    },
  }
</script>

<style>
</style>

2.创建 List.vue和Profile.vue两个视图组件

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

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

<style scoped>

</style>

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

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

<style scoped>

</style>

3.修改router文件夹下的index.js

/**
 * 配置路由
 */
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:'/login',
      component:Login
    },{
      path:'/main',
      component:Main,
      children:[ //嵌套路由
        {path:'/user/profile',component:UserProfile},
        {path:'/user/list',component:UserList}
      ]
    }
  ]
});
