因为我暂时不需要第五章和第六章教程的内容所以直接进入第七章。感兴趣的可以访问原作者网站
注：本次封装的css样式应该有点问题，但考虑时间问题没有认真修改，后续有时间重构时候补上。
组件封装
模块化，提升后期的可维护性
组件结构
Home.vue

Main.vue
<template>
<div class="main-container">
<el-breadcrumb separator="/" class="breadcrumb">

<script>
export default {

mounted() {

<style scoped lang="scss">
.main-container {
position: absolute;
top: 60px;
bottom: 0px;
left: 200px;
right: 0px;
background: #fff;
.breadcrumb {
padding: 10px;
border-color: rgba(38, 86, 114, 0.2);
border-bottom- 1px;
border-bottom-style: solid;
background: rgba(138, 158, 170, 0.2);
}
}
</style>
然后修改路由
import Vue from "vue"; import VueRouter from "vue-router"; Vue.use(VueRouter); const routes = [ { path: "/", name: "Home", component: () => import ("@/views/home"), children: [ { path: '', name: '系统介绍', component: () => import ("@/views/Intro") }, { path: '/user', name: '用户管理', component: () => import ("@/views/SysMng/User") }, { path: '/dept', name: '系统介绍', component: () => import ("@/views/SysMng/Dept") }, { path: '/role', name: '系统介绍', component: () => import ("@/views/SysMng/Role") }, { path: '/menu', name: '菜单管理', component: () => import ("@/views/SysMng/Menu") }, { path: '/log', name: '系统介绍', component: () => import ("@/views/SysMng/Log") }, ] }, { path: '/login', name: 'Login', component: () => import ("@/views/common/Login") }, { path: '/404', name: 'notFound', component: () => import ("@/views/common/404") } ]; const router = new VueRouter({ routes }); // 导航守卫 router.beforeEach((to, from, next) => { // 登入界面成功之后，会把用户信息保存在会话 // 存在时间为会话生命周期，页面关闭既失效 let user = sessionStorage.getItem('user'); if(to.path == '/login') { // 访问登入界面，如果用户会话信息存在，代表已登入过，转跳到主页 if(user) { next({ path: '/' }) }else { next() } }else { // 访问非登入界面，且用户信息不存在，代表未登入，则转跳到登入界面 if(!user) { next({ path: '/login' }) }else { next() } } }) export default router;
显示效果
