1.搭建vue的开发环境:
1.必须要安装node.js
2.安装vue的脚手架工具 官方命令行工具
npm install --global vue-cli
3.新建项目
vue init webpack-simple gw
然后一直回车,新建完成后,cd到gw目录下,执行
cnpm install
4.运行项目
npm run dev
运行成功后,可以通过访问
http://localhost:8080/
2.vue路由
vue路由的意思就是不用手动挂载组件,实现动态挂载的方式
1.基础路由
1. 安装vue-router
cnpm install vue-router --save
2.在src/main.js中
import Vue from 'vue' import App from './App.vue' import VueRouter from 'vue-router'; Vue.use(VueRouter); //1.创建组件 import Home from './components/Home.vue'; import New from './components/New.vue'; //2.配置路由 const routes=[ {path:'/home',component:Home}, {path:'/news',component:New}, {path:'*',redirect:'/home'} ] //3.实例化VueRouter const router=new VueRouter({ routes }) //4.挂载路由 new Vue({ el: '#app', router, render: h => h(App) }) //5.在根组件App.vue的模板中,放入<router-view></router-view>
3.在src/App.vue中
<template> <div id="app"> <router-view></router-view> </div> </template> <script> export default { name: 'app', data () { return { msg:'你好' } } } </script> <style> </style>
4.重新运行项目,访问:
http://localhost:8080/#/home
http://localhost:8080/#/news
即可看到两个组件被挂载了。
2.路由跳转
1.通过标签跳转
1.在src/App.vue的模板中加入router-link
<template> <div id="app"> <router-link to="/home">首页</router-link> <router-link to="/news">新闻</router-link> <hr> <router-view></router-view> </div> </template> <script> export default { name: 'app', data () { return { msg:'你好' } } } </script> <style> </style>
2.通过js跳转
1.在src/components/Home.vue中
<template> <div> <h2>这是一个首页组件</h2> <v-header></v-header> <button @click="goNews()">通过js跳转到新闻页面</button> </div> </template> <script> export default { methods:{ goNews(){ this.$router.push({path:'/news'}) } } } </script> <style> </style>
3.父子路由
1.在src/components目录下新建User.vue文件,同时再新建User目录,在User目录下新建UserAdd.vue和UserList.vue两个文件
User.vue
<template> <div id="user"> <div class="user"> <div class="left"> <ul> <li> <router-link to="/user/useradd">增加用户</router-link> </li> <li> <router-link to="/user/userlist">用户列表</router-link> </li> </ul> </div> <div class="right"> <router-view></router-view> </div> </div> </div> </template> <script> export default { } </script> <style lang="scss" scoped> .user{ display: flex; .left{ width: 200px; min-height: 400px; border-right: 1px solid #eee } .right{ flex: 1; } } </style>
UserAdd.vue
<template> <div id="adduser"> 用户增加 </div> </template>
UserList.vue
<template> <div id="userlist"> 用户列表 </div> </template>
3.在src/main.js中
import Vue from 'vue' import App from './App.vue' import VueRouter from 'vue-router'; Vue.use(VueRouter); //1.创建组件 import Home from './components/Home.vue'; import New from './components/New.vue'; import User from './components/User.vue'; import UserAdd from './components/User/UserAdd.vue'; import UserList from './components/User/UserList.vue'; //2.配置路由 const routes=[ {path:'/home',component:Home}, {path:'/news',component:New}, { path:'/user', component:User, children:[ {path:'useradd',component:UserAdd}, {path:'userlist',component:UserList} ] }, {path:'*',redirect:'/home'} ] //3.实例化VueRouter const router=new VueRouter({ // mode:'history', routes }) //4.挂载路由 new Vue({ el: '#app', router, render: h => h(App) }) //5.在根组件App.vue的模板中,放入<router-view></router-view>
4.路由模块化
1.在src目录下新建router目录,router目录下新建router.js
import Vue from 'vue' import VueRouter from 'vue-router'; Vue.use(VueRouter); //1.创建组件 import Home from '../components/Home.vue'; import New from '../components/New.vue'; import User from '../components/User.vue'; import UserAdd from '../components/User/UserAdd.vue'; import UserList from '../components/User/UserList.vue'; //2.配置路由 const routes=[ {path:'/home',component:Home}, {path:'/news',component:New}, { path:'/user', component:User, children:[ {path:'useradd',component:UserAdd}, {path:'userlist',component:UserList} ] }, {path:'*',redirect:'/home'} ] //3.实例化VueRouter const router=new VueRouter({ // mode:'history', routes }) export default router; //5.在根组件App.vue的模板中,放入<router-view></router-view>
2.在src/main.js中
import Vue from 'vue' import App from './App.vue' import router from './router/router.js'; //4.挂载路由 new Vue({ el: '#app', router, render: h => h(App) })
3.element UI的使用
官网
http://element-cn.eleme.io/#/zh-CN/component/installation
1.安装
cnpm i element-ui -S //-S表示 --save
2.将配置代码引入main.js中
配置代码:
import ElementUI from 'element-ui'; import 'element-ui/lib/theme-chalk/index.css'; Vue.use(ElementUI);
main.js
import Vue from 'vue' import App from './App.vue' //elementsUI 的使用 import ElementUI from 'element-ui'; import 'element-ui/lib/theme-chalk/index.css'; Vue.use(ElementUI); import VueRouter from 'vue-router'; Vue.use(VueRouter); //1.创建组件 import Home from './components/Home.vue'; import New from './components/New.vue'; import User from './components/User.vue'; import UserAdd from './components/User/UserAdd.vue'; import UserList from './components/User/UserList.vue'; //2.配置路由 const routes=[ {path:'/home',component:Home}, {path:'/news',component:New}, { path:'/user', component:User, children:[ {path:'useradd',component:UserAdd}, {path:'userlist',component:UserList} ] }, {path:'*',redirect:'/home'} ] //3.实例化VueRouter const router=new VueRouter({ // mode:'history', routes }) //4.挂载路由 new Vue({ el: '#app', router, render: h => h(App) }) //5.在根组件App.vue的模板中,放入<router-view></router-view>
3.配置webpack.config.js,加入字体配置代码
配置代码
{ test: /.(eot|svg|ttf|woff|woff2)(?S*)?$/, loader: 'file-loader' },
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: { rules: [ { test: /.css$/, use: [ 'vue-style-loader', 'css-loader' ], }, { test: /.vue$/, loader: 'vue-loader', options: { loaders: { } // other vue-loader options go here } }, { test: /.js$/, loader: 'babel-loader', exclude: /node_modules/ }, { test: /.(png|jpg|gif|svg)$/, loader: 'file-loader', options: { name: '[name].[ext]?[hash]' } }, { test: /.(eot|svg|ttf|woff|woff2)(?S*)?$/, loader: 'file-loader' } ] }, resolve: { alias: { 'vue$': 'vue/dist/vue.esm.js' }, extensions: ['*', '.js', '.vue', '.json'] }, devServer: { historyApiFallback: true, noInfo: true, overlay: true }, performance: { hints: false }, devtool: '#eval-source-map' } if (process.env.NODE_ENV === 'production') { module.exports.devtool = '#source-map' // http://vue-loader.vuejs.org/en/workflow/production.html module.exports.plugins = (module.exports.plugins || []).concat([ new webpack.DefinePlugin({ 'process.env': { NODE_ENV: '"production"' } }), new webpack.optimize.UglifyJsPlugin({ sourceMap: true, compress: { warnings: false } }), new webpack.LoaderOptionsPlugin({ minimize: true }) ]) }
然后重启项目,发现不报错了。
4.vuex
vuex是一个专门为vue.js应用程序开发的状态管理模式,解决不同组件之间的同一状态共享问题,数据共享问题,数据持久化
1.安装
cnpm install vuex --save
2.在src目录下新建目录vuex,在vuex目录下新建store.js文件
import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex); // 1.state在vuex中用于储存数据 var state={ count:1 } // 2.mutations里面放的是方法,方法主要内容用于改变state里面的数据 var mutations={ incCount(){ ++state.count } } // 实例化Vuex.store const store=new Vuex.Store({ state, mutations:mutations }) export default store;
3.在src/components/Home.vue中使用
<template> <div> <h2>这是一个首页组件</h2> <button @click="goNews()">通过js跳转到新闻页面</button> <!-- 3.使用 --> <h2>全局变量--{{this.$store.state.count}}</h2> <h2>{{this.i}}</h2> <button @click="addcount()">增加数量+</button> </div> </template> <script> // 1.引入store import store from '../vuex/store.js'; // 2.注册 export default { store, methods:{ goNews(){ this.$router.push({path:'/news'}) }, addcount(){ // 改变vuex.store里面的数据 this.$store.commit('incCount'); } }, data(){ return{ i:0 } }, mounted(){ this.i=this.$store.state.count } } </script> <style> </style>
5.使用iview
官网
https://www.iviewui.com/docs/guide/install
1.安装
cnpm install iview --save
2.在src/main.js加入
import iView from 'iview' import 'iview/dist/styles/iview.css' // 使用 CSS Vue.use(iView)
3.配置webpack.config.js,加入字体配置代码
配置代码
{ test: /.(eot|svg|ttf|woff|woff2)(?S*)?$/, loader: 'file-loader' },
webpack.config.js
然后重启项目,发现不报错了。
