Vue 2.0 + Vue Router + Vuex
用 Vue.js 2.x 与相配套的 Vue Router、Vuex 搭建了一个最基本的后台管理系统的骨架。
当然先要安装 node.js(包括了 npm)、vue-cli
项目结构如图所示:
assets 中是静态资源,components 中是组件(以 .vue 为后缀名的文件),store 中是使用了 vuex 的 js 文件。
package.json:
{ "name": "element-starter", "description": "A Vue.js project", "author": "caihg", "private": false, "scripts": { "dev": "cross-env NODE_ENV=development webpack-dev-server --inline --hot --open", "build": "cross-env NODE_ENV=production webpack --progress --hide-modules" }, "dependencies": { "element-ui": "^1.0.0", "vue": "^2.1.0", "vue-router": "^2.1.1", "vue-server-renderer": "^2.1.3", "vuex": "^2.0.0", "vuex-router-sync": "^3.0.0" }, "devDependencies": { "babel-core": "^6.0.0", "babel-loader": "^6.0.0", "babel-preset-es2015": "^6.13.2", "cross-env": "^1.0.6", "css-loader": "^0.23.1", "file-loader": "^0.8.5", "style-loader": "^0.13.1", "vue-loader": "^10.0.0", "vue-template-compiler": "^2.1.0", "webpack": "^2.1.0-beta.25", "webpack-dev-server": "^2.1.0-beta.0", "webpack-dev-middleware": "^1.6.1" } }
webpack.config.js:
var path = require('path') var webpack = require('webpack') module.exports = { entry: './src/main.js', output: { path: path.resolve(__dirname, './dist'), publicPath: '/dist/', filename: 'build.js' }, module: { loaders: [ { test: /\.vue$/, loader: 'vue-loader' }, { test: /\.js$/, loader: 'babel-loader', exclude: /node_modules/ }, { test: /\.css$/, loader: 'style-loader!css-loader' }, { test: /\.(eot|svg|ttf|woff|woff2)(\?\S*)?$/, loader: 'file-loader' }, { test: /\.(png|jpe?g|gif|svg)(\?\S*)?$/, loader: 'file-loader', query: { name: '[name].[ext]?[hash]' } } ] }, devServer: { historyApiFallback: true, noInfo: true }, devtool: '#eval-source-map' } if (process.env.NODE_ENV === 'production') { module.exports.devtool = '#source-map' module.exports.plugins = (module.exports.plugins || []).concat([ new webpack.DefinePlugin({ 'process.env': { NODE_ENV: '"production"' } }), new webpack.optimize.UglifyJsPlugin({ compress: { warnings: false } }) ]) }
项目的入口 js 文件 main.js:
import Vue from 'vue' import VueRouter from 'vue-router' import ElementUI from 'element-ui' import 'element-ui/lib/theme-default/index.css' Vue.use(VueRouter) Vue.use(ElementUI) import routes from './routes' const router = new VueRouter({ mode: 'history', base: __dirname, routes: routes }) import Main from './components/main.vue' new Vue({ el: '#app', router, render: h => h(Main) })
该文件引用了路由配置文件 routes.js 和主入口的组件 main.vue,其中 main.vue 在 components 目录
routes.js 内容如下:
import Login from './components/login/login.vue' import Container from './components/container/container.vue' import UserHome from './components/container/userHome.vue' import Platform from './components/asideContainer/platform.vue' import UserList from './components/platform/userList.vue' import UserCreate from './components/platform/userCreate.vue' import Product from './components/asideContainer/product.vue' import ProductList from './components/product/list.vue' import ProductBrand from './components/product/brand.vue' import NotFound from './components/error/notFound.vue' export default [ { path: '/login', component: Login }, { path: '/', redirect: '/login' }, { path: '/page', component: Container, children: [ { path: 'userHome', component: UserHome }, { path: 'platform', redirect: 'platform/userList', // 默认指向用户列表(UserList) component: Platform, children: [ { path: 'userList', component: UserList }, { path: 'userCreate', component: UserCreate } ] }, { path: 'product', redirect: 'product/list', // 默认指向商品列表(ProductList) component: Product, children: [ { path: 'list', component: ProductList }, { path: 'brand', component: ProductBrand } ] } ] }, { // 404页面:必须位于最后,否则其它的路由地址都会使用 NotFound 组件 path: '*', component: NotFound } ]
main.vue 的内容如下:
<template> <router-view></router-view> </template>
store.js 在 store 目录,内容如下:
import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) export default new Vuex.Store({ state: { username: '' } })
后台都是登录成功后跳转到主页面
界面的 UI 用的是开源的 element-ui
login.vue 位于 login 目录,内容如下:
<template> <div class="box"> <el-form :model="loginForm" :rules="loginRules" ref="loginForm" label-width="100px" class="form-box"> <el-form-item label="用户名" prop="username"> <el-input v-model="loginForm.username" placeholder="请输入用户名" auto-complete="off"></el-input> </el-form-item> <el-form-item label="密码" prop="password"> <el-input type="password" v-model="loginForm.password" auto-complete="off"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="onLogin">登录</el-button> <el-button @click="handleReset">重置</el-button> </el-form-item> </el-form> </div> </template> <script> import store from '../../store/store' export default { data() { var validateUsername = (rule, value, callback) => { if (value === '') { callback(new Error('请输入用户名')); } else { callback(); } }; var validatePassword = (rule, value, callback) => { if (value === '') { callback(new Error('请输入密码')); } else { callback(); } }; return { loginForm: { username: '', password: '' }, loginRules: { username: [ { validator: validateUsername, trigger: 'blur' } ], password: [ { validator: validatePassword, trigger: 'blur' } ] } }; }, methods: { onLogin(event) { this.$refs.loginForm.validate((valid) => { if (valid) { store.state.username = this.loginForm.username; this.$router.push('page/userHome'); } else { console.log('error submit!!'); return false; } }); }, handleReset() { this.$refs.loginForm.resetFields(); } } } </script> <style> .form-box { width: 500px; margin-top: 100px; margin-right: auto; margin-left: auto; } </style>
在登录事件中,将用户名传递给 store 中的 state.username,以便在其它组件中获取:
store.state.username = this.loginForm.username
登录后的界面,默认跳转到主页:
通过 vuex 获取到了登录的用户名称(caihg);当然,如果刷新当前页面,用户名称就没了。
头部在 container 目录,其中有三个组件
container.vue 的内容如下:
<template> <div class="container"> <header-nav></header-nav> <router-view></router-view> </div> </template> <script> import headerNav from './headerNav.vue' export default { components: { headerNav } } </script> <style> header > h1 { display: inline-block; } header > a { margin: 0 10px; color: #000; text-decoration: none; } </style>
headerNav.vue 中就是头部导航的各种链接:
<template> <header> <h1>管理平台</h1> <router-link to="/page/userHome">主页</router-link> <router-link to="/page/platform">平台管理</router-link> <router-link to="/page/product">商品管理</router-link> <strong>欢迎你,{{ getUsername }}</strong> </header> </template> <script> import store from '../../store/store' export default { computed: { getUsername () { return store.state.username } } } </script> <style> header > .router-link-active { color: red; } header > strong { padding-left: 50px; } </style>
点击头部的导航,下面的内容相应地切换
其中左侧部分也是导航,点击也要跟随切换
左侧的导航放在 asideContainer 目录
platform.vue 与 product.vue 内容相似;只是前者包括了样式,后者没有(相同的样式写一份就够了,如果多写了,也会重复渲染)
<template> <!-- 平台管理 --> <div> <ul class="aside-nav"> <li><router-link to="/page/platform/userList">用户列表</router-link></li> <li><router-link to="/page/platform/userCreate">用户创建</router-link></li> </ul> <router-view class="aside-container"></router-view> </div> </template> <style> .aside-nav { float: left; width: 100px; margin: 0 50px 0 0; padding-left: 0; } .aside-nav a { display: block; padding: 4px 0 5px; color: #555; text-align: center; text-decoration: none; } .aside-nav .router-link-active { color: #fff; background-color: orange; } .aside-container { float: left; } </style>
<template> <!-- 商品管理 --> <div> <ul class="aside-nav"> <li><router-link to="/page/product/list">商品列表</router-link></li> <li><router-link to="/page/product/brand">商品品牌</router-link></li> </ul> <router-view class="aside-container"></router-view> </div> </template>
左侧导航对应的内容分别在不同的目录(根据功能划分)
userList.vue 中的内容如下:
<template>
<div>
用户列表的内容
</div>
</template>
至此完成,后台管理系统的大致骨架就是这样了。
