1.1 认识Mock.js Mock.js是一个用于前端开发中生成随机数据、模拟接口响应的 JavaScript 库。模拟数据的生成器用来帮助前端调试开发、进行前后端的原型分离以及用来提高自动化测试效率 总结来说Element中的Mock.js是一个用于前端开发中生成随机数据、模拟接口响应的库。它可以帮助你快速开发和调试前端项目而无需依赖后端接口 1.2 安装mockjs npm i mockjs -D 注意在SPA项目工作区间使用cmd执行该命令 -D表示只在开发环境中使用 执行完毕之后在devDependencies下会发现已下载好mockjs插件证明已经安装好了 1.3 引入mockjs 为了只在开发环境使用mock而打包到生产环境时自动不使用mock我们可以在config目录中的dev.env.js和prod.env.js做一个配置如下 dev.env.js(开发坏境): 加入Mock:true 如下 module.exports merge(prodEnv, {NODE_ENV: development,MOCK: true
}) prod.env.js(生产坏境): 加入Mock:flase 如下 module.exports {NODE_ENV: production,MOCK: false
} mian.js导入Mock动态依赖 //开发环境下才会引入mockjs
process.env.MOCK require(/mock) 二 mockjs使用 导入两个js login-mock: // const loginInfo {
// code: -1,
// message: 密码错误
// }//使用mockjs的模板生成随机数据
const loginInfo {code|-1-0: 0,message|3-10: msg
}

/style② 给组件配置路由关系 index.js: import Vue from vue
import Router from vue-router
import HelloWorld from /components/HelloWorld
import AppMain from /components/AppMain
import LeftNav from /components/LeftNav
import TopNav from /components/TopNav
import Login from /views/Login
import Register from /views/RegisterVue.use(Router)export default new Router({routes: [{path: /,name: Login,component: Login},{path: /Register,name: Register,component: Register,},{path: /AppMain,name: AppMain,component: AppMain,children:[{path: /LeftNav,name: LeftNav,component: LeftNav,},{path: /TopNav,name: TopNav,component: TopNav}]}]
}) Login.vue跳转到AppMain(登入跳到主界面) this.$router.push(/AppMian); 3.2 结合总线完成组件通讯 Bus事件适用于父子组件、非父子组件等之间的通信
定义Bus总线main.js
new Vue({el: #app,data(){return{Bus:new Vue()}},router,components: { App },template: App/
})
TopNav.vue:
methods:{doToggle(){//收起左侧菜单事件this.collapsed!this.collapsed;//将是否折叠的变量放入总线this.$root.Bus.$emit(aaa,this.collapsed);},exit(){//退出事件this.$router.push(/)}} collapsed默认flase,当我们点击的时候就会取反flase就会变为true,并把是否折叠的变量放入总线中方便其他组件调取
LeftNav.vue: created(){this.$root.Bus.$on(aaa,r{this.collapsedr;});}
在组件创建时订阅了一个名为 aaa 的事件并在事件触发时将接收到的数据赋值给 collapsed 属性。
AppMain.vue:
created(){this.$root.Bus.$on(aaa,r{this.asideClassr ? main-aside-collapsed:main-aside;});}
效果图
