最终演示效果 前言 在之前的博客中与各位老铁分享一些有关Vue的知识想必也给大家带来了一帮助与收获例如ElementUI实现登陆注册、vue-cli搭建SPA项目、路由等等。今天与各位老铁带来的是Element来搭建页面首页的导航及左侧的菜单模块。 一、mockjs简介
1. 什么是mockjs MockJS 是一款前端开发中常用的模拟数据生成工具用于在开发过程中模拟接口返回数据。它可以帮助前端开发人员独立于后端接口进行开发和调试提高开发效率。MockJS 提供了一套简单却强大的 API可以根据指定的规则生成随机的模拟数据。通过 MockJS开发者可以定义接口的返回结构、数据类型以及各种约束条件例如字符串长度、数字范围、日期格式等从而模拟真实的接口返回结果。 MockJS 的使用非常灵活可以配合其他前端框架如 Vue、React、Angular或纯 JavaScript 进行集成。它还支持在浏览器环境和 Node.js 服务器环境中运行适用于各种场景下的模拟数据需求。 通过使用 MockJS开发者可以快速搭建前端开发环境独立地进行开发和调试在后端接口未完成或不可用的情况下仍然能够保持项目的正常进行。同时MockJS 还可以用于编写自动化测试用例方便进行接口测试和调试工作。 2. mockjs的用途 Mock.js 是一个模拟数据生成器可以帮助前端开发者快速生成模拟数据方便进行前端开发和前后端分离开发。具体的应用场景有 前端开发时可以用 Mock.js 生成模拟的接口数据方便前端进行功能开发和调试而不依赖后端接口的实现。 前后端分离开发时前端可以使用 Mock.js 提供的模拟数据生成功能随时随地进行开发和测试。当后端接口完成后只需更改配置将 Mock.js 替换为后端接口的请求即可。 在线教育平台等需要大量测试数据的应用场景中可以使用 Mock.js 生成大量的随机数据用于测试和演示。 在项目初期当后端接口还未开发完成时可以使用 Mock.js 生成模拟数据给前端项目提供一些数据展示效果。 3. 运用mockjs的优势 优势主要包括 数据类型丰富MockJS支持生成随机的文本、数字、布尔值、日期、邮箱、链接、图片、颜色等这有助于在开发过程中模拟各种数据情况帮助开发者更好地进行测试和调试。拦截Ajax请求MockJS可以在不修改既有代码的情况下拦截Ajax请求并返回模拟的响应数据这对于在开发过程中模拟服务器响应或进行本地测试非常有用。前后端分离MockJS可以帮助前端独立于后端进行开发这对于前后端分离的开发模式非常有益可以加快开发进度和提高效率。单元测试MockJS的随机数据模拟功能可以帮助开发者在单元测试中增加测试的真实性通过模拟各种场景来提高测试的完整性和可靠性。无侵入性MockJS不需要修改既有代码就可以进行拦截和模拟这对于不希望修改生产代码的场景非常适用比如在进行前端开发时进行接口测试。简单易用MockJS的接口符合直觉易于使用使得开发者可以快速上手并开始使用。方便扩展MockJS支持扩展更多数据类型支持自定义函数和正则表达式这使得MockJS可以满足更多的开发需求。二、 二、安装与配置mockjs
1. 安装mockjs
在项目的目录下进入cmd终端窗口输入一下指令进行安装。 npm i mockjs -D 注-D表示只在开发环境中使用 2. 引入mockjs
2.1 dev.env.js
module.exports merge(prodEnv, {NODE_ENV: development,MOCK: true
}) 2.2 prod.env.js
module.exports {NODE_ENV: production,MOCK: false
} 2.3 main.js 在动态main.js中加载mockjs,在开发环境下才会使用生产环境不会使用。 //开发环境下才会引入mockjs
process.env.MOCK require(/mock) 三、mockjs的使用
1. 将资源中的mock文件夹复制到src目录下 该文件下的json文件夹中的login-mock.js是用来创造模拟数据的index.js是用来将数据与登陆请求进行绑定的。 2. 点击登陆进行模拟测试 点击多次登陆后code可能发生改变-1/0但是message的长度不一。 模拟当前登陆成功与失败不进行后端交互 Login.vue

/style3. 配置路由与组件的关系
index.js
import Vue from vue
import Router from vue-router
import HelloWorld from /components/HelloWorldimport AppMain from /components/AppMain
import LeftNav from /components/LeftNav
import TopNav from /components/TopNavimport Login from /views/Login
import Register from /views/RegisterVue.use(Router)export default new Router({routes: [ //默认首页{path: /,name: Login,component: Login}, {path: /Register,name: Register,component: Register}, {path: /Login,name: Login,component: Login}, {path: /AppMain,name: AppMain,component: AppMain,children;[{path: /LeftNav,name: LeftNav,component: LeftNav}, {path: /TopNav,name: TopNav,component: TopNav}]}]
})4. 实现登陆跳转主页 this.$router.push(/AppMain); 这只是半成品后还需进行调整才能显示样式和效果。 5. 最终代码
