一、效果展示

初步设计一个系统，有目录、搜索栏、表格操作等。

二、参考代码

主要关注上图“App.vue”和“BtestView.vue”两个文件的代码

1、App.vue

<template>
  <div >
    <!-- <h1>{{ message }}</h1> -->
    <!-- <element-view></element-view> -->
    <!--<emp-view></emp-view>-->
    <Btest-view></Btest-view>
  </div>
</template>

<script>
//import empView from './views/systemTest/empView.vue'
import BtestView from './views/systemTest/BtestView.vue'
//import ElementView from './views/element/ElementView.vue'
export default {
  //components: { empView },
  //components: { ElementView },
  components: { BtestView },
  data() {
    return {
      message: "Hello world!" 
    }
  },
  methods: {
    
  }
}
</script>

<style>

</style>

2、BtestView.vue

<template>
    <div>
        <el-container style="height: 800px; border: 1px solid #eee">
            <el-header style="font-size: 40px;background-color: rgb(238, 241, 246)">智能学习辅助系统</el-header>

            <el-container>
                <el-aside width="230px" style=" border: 1px solid #eee">
                    <!-- 目录</el-aside> -->
                    <!-- <br> -->
                    <el-menu :default-openeds="['1', '3']">
                    <el-submenu index="1">
                        <template slot="title"><i class="el-icon-message"></i>系统信息管理</template>

                        <el-menu-item index="1-2">员工管理</el-menu-item>                           
                        </el-menu-item-group> 
                    </el-submenu>            
                <el-submenu index="2">

三、知识整理

1、vue项目中使用Axios异步加载数据，需要：

1）在项目目录下安装axios:
