vueelementUI_0">vue-elementUI

能快速的让网站上线

直接看官方文档，里面的文档很详细

https://element.eleme.cn/#/zh-CN

直接全部从头来一遍
vue-router自己安装的时候老是容易出问题
直接让他默认安装

C:\Users\haoyun\Desktop\vue\vue-elementUI>npm i element-ui -S

安装elementUI
安装SASS加速器

cnpm install sass-loader node-sass --save-dev

启动测试一下npm run dev

提示框
输入正确会跳转到Main页面

路由嵌套

对于组件来说只是对局部的改变

主要流程
- 创建两个组件
- 路由注册两个组件
- 首页通过路径点击事件通过路由找到组件，将组件渲染上去

个人信息绑定了/user/profile，就会通过路由找到/main路径下的/user/profile对应的组件

vue"><el-menu-item index="1-1">
  <router-link to="/user/profile">个人信息</router-link>
</el-menu-item>

{
  path: '/main',
  component: Main,
  children:[
    {
      path:"/user/profile",
      component:UserProfile
    },{
      path:"/user/list",
      component:UserList
    }
  ]
}
