組件封裝

為了避免組件代碼的臃腫，這里對主要的功能部件進(jìn)行封裝，保證代碼的模塊化和簡潔度。

組件結(jié)構(gòu)

組件封裝重構(gòu)后，試圖組件結(jié)構(gòu)如下圖所示

代碼一覽

Home組件被簡化，包含導(dǎo)航、頭部和主內(nèi)容三個組件。

Home.vue

<template><div class="container"><!-- 導(dǎo)航菜單欄 --><MenuBar></MenuBar><!-- 頭部區(qū)域 --><HeadBar></HeadBar><!-- 主內(nèi)容區(qū)域 --><Main></Main></div> </template><script> import HeadBar from "./HeadBar/HeadBar" import MenuBar from "./MenuBar/MenuBar" import Main from "./Main/Main" export default {components:{HeadBar,MenuBar,Main} }; </script><style scoped lang="scss">.container {position:absolute;top: 0px;left: 0px;right: 0px;background: #4b5f6e;} </style>

Main.vue

<template><div class="container"><el-breadcrumb separator="/" class="breadcrumb"><el-breadcrumb-item v-for="item in $route.matched" :key="item.path"><a href="www.baidu.com">{{ item.name }}</a></el-breadcrumb-item></el-breadcrumb><transition name="fade" mode="out-in"><router-view></router-view></transition></div> </template><script> export default {data() {return {};},methods: {},mounted() {} }; </script><style scoped lang="scss"> .container {position: absolute;top: 60px;bottom: 0px;left: 200px;right: 0px;.breadcrumb {padding: 10px; border-color: rgba(38, 86, 114, 0.2);border-bottom-width: 1px;border-bottom-style: solid;background: rgba(138, 158, 170, 0.2);} } </style>

國際化語言切換也被封裝成為了組件?LangSelector

LangSelector/index.js

<template><el-dropdown class="lang-selector" @command="handleCommand"><span class="el-dropdown-link"><span id="language">中文</span><i class="el-icon-arrow-down el-icon--right"></i></span><el-dropdown-menu slot="dropdown"><el-dropdown-item command="zh_cn:中文">中文</el-dropdown-item><el-dropdown-item command="en_us:English">English</el-dropdown-item></el-dropdown-menu></el-dropdown> </template><script>export default {methods: {// 語言切換 handleCommand(command) {let array = command.split(':')let lang = array[0] === '' ? 'zh_cn' : array[0]let label = array[1]document.getElementById("language").innerHTML = labelthis.$i18n.locale = lang}}} </script>

組件封裝重構(gòu)之后，同步修改路由配置

import Vue from 'vue' import Router from 'vue-router' import Login from '@/views/Login' import NotFound from '@/views/404' import Home from '@/views/Home' import Intro from '@/views/Intro' import User from '@/views/SysMng/User' import Dept from '@/views/SysMng/Dept' import Role from '@/views/SysMng/Role' import Menu from '@/views/SysMng/Menu' import Log from '@/views/SysMng/Log'Vue.use(Router)const router = new Router({routes: [{path: '/',name: '首頁',component: Home,children: [{ path: '', component: Intro, name: '系統(tǒng)介紹' },{ path: '/user', component: User, name: '用戶管理' },{ path: '/dept', component: Dept, name: '機構(gòu)管理' },{ path: '/role', component: Role, name: '角色管理' },{ path: '/menu', component: Menu, name: '菜單管理' },{ path: '/log', component: Log, name: '日志管理' }]},{path: '/login',name: '登錄',component: Login},{path: '/404',name: 'notFound',component: NotFound}] })router.beforeEach((to, from, next) => {// 登錄界面登錄成功之后，會把用戶信息保存在會話// 存在時間為會話生命周期，頁面關(guān)閉即失效。let user = sessionStorage.getItem('user');if (to.path == '/login') {// 如果是訪問登錄界面，如果用戶會話信息存在，代表已登錄過，跳轉(zhuǎn)到主頁if(user) {next({ path: '/' })} else {next()}} else {// 如果訪問非登錄界面，且戶會話信息不存在，代表未登錄，則跳轉(zhuǎn)到登錄界面if (!user) {next({ path: '/login' })} else {next()}} })export default router

測試效果

封裝重構(gòu)之后，啟動界面，效果跟之前差別不大。
