const routes = [ { path: ’/’, name: ’導(dǎo)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: ’頁(yè)面1’,component: PageOne, }, {path: ’/pageTwo’,name: ’頁(yè)面2’,component: PageTwo, }, ] }, { path: ’/navigation’, name: ’導(dǎo)航2’, component: Home, children:[ {path: ’/pageThree’,name: ’頁(yè)面3’,component: PageThree, }, {path: ’/pageFour’,name: ’頁(yè)面4’,component: PageFour }, ] },二、vue頁(yè)面嵌套

App.vue先配置第一個(gè)router-view

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

Home.vue配置第二個(gè)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>刪除</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、嵌套聯(lián)系

首先，在訪問(wèn)http://localhost:8181/時(shí)會(huì)進(jìn)入第一層嵌套，此時(shí)進(jìn)入第一個(gè)router-view：Home.vue。然后當(dāng)訪問(wèn)pageone時(shí)，會(huì)連帶Home.vue繼續(xù)訪問(wèn)。

因?yàn)閞outer-view的嵌套顯示和路由路基的嵌套有關(guān)，可以看到，在路由里面，導(dǎo)航一的路徑底下分別是頁(yè)面一以及頁(yè)面二的路由路徑。所以當(dāng)訪問(wèn)頁(yè)面一pageone時(shí)，會(huì)先訪問(wèn)上級(jí)路徑Home.vue頁(yè)面。加入Home.vue頁(yè)面沒(méi)有放置router-view，那么下級(jí)頁(yè)面將無(wú)法顯示

到此這篇關(guān)于vue router-view的嵌套顯示實(shí)現(xiàn)的文章就介紹到這了,更多相關(guān)vue router-view嵌套顯示內(nèi)容請(qǐng)搜索好吧啦網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持好吧啦網(wǎng)！
