vue router-view的嵌套显示实现

const routes = [ { path: ’/’, name: ’导航1’, component: Home, children:[ {path: ’/customer’,name: ’Customer’,// route level code-splitting// this generates a separate chunk (about.[hash].js) for this route// which is lazy-loaded when the route is visited.component: () => import(/* webpackChunkName: 'about' */ ’../views/Customer.vue’) }, {path: ’/pageOne’,name: ’页面1’,component: PageOne, }, {path: ’/pageTwo’,name: ’页面2’,component: PageTwo, }, ] }, { path: ’/navigation’, name: ’导航2’, component: Home, children:[ {path: ’/pageThree’,name: ’页面3’,component: PageThree, }, {path: ’/pageFour’,name: ’页面4’,component: PageFour }, ] },二、vue页面嵌套

App.vue先配置第一个router-view

// An highlighted block <router-view></router-view>

Home.vue配置第二个router-view

// An highlighted block<template> <div> <el-container style='height: 500px; border: 1px solid #eee'> <el-aside style='background-color: rgb(238, 241, 246)'> <el-menu><el-submenu v-for='(item,index) in $router.options.routes' :index='index+’’'><template slot='title'><i class='el-icon-sell'></i>{{item.name}}</template> <el-menu-item v-for='(item2,index2) in item.children' :index='index+’-’+index2'>{{item2.name}}</el-menu-item></el-submenu> </el-menu> </el-aside> <el-container> <el-header style='text-align: right; font-size: 12px'><el-dropdown> <i style='margin-right: 15px'></i> <el-dropdown-menu slot='dropdown'> <el-dropdown-item>查看</el-dropdown-item> <el-dropdown-item>新增</el-dropdown-item> <el-dropdown-item>删除</el-dropdown-item> </el-dropdown-menu></el-dropdown><span>王小虎</span> </el-header> <el-main><router-view></router-view> </el-main> </el-container> </el-container></div></template><style>.el-header { background-color: #B3C0D1; color: #333; line-height: 60px;}.el-aside { color: #333;}</style><script>export default {};</script>三、嵌套联系

首先，在访问http://localhost:8181/时会进入第一层嵌套，此时进入第一个router-view：Home.vue。然后当访问pageone时，会连带Home.vue继续访问。

因为router-view的嵌套显示和路由路基的嵌套有关，可以看到，在路由里面，导航一的路径底下分别是页面一以及页面二的路由路径。所以当访问页面一pageone时，会先访问上级路径Home.vue页面。加入Home.vue页面没有放置router-view，那么下级页面将无法显示
