安装工具环境和依赖

环境

启动一个项目

1. Vue 创建项目 vue create ly_project
2. 进入项目 cd ly_project
3. 添加element-ui依赖 npm i element-ui -S
4. 启动项目 npm run serve
5. idea打开项目文件ly_project
6. 安装vue.js插件重启idea

搭建后端页面

1. 利用element-ui模板生成html页面

<template>
    <el-container>
      <el-aside :width="sideWidth + 'px'" style="background-color: rgb(238, 241, 246); height: 100vh">

        <el-menu :default-openeds="['1', '3']" style="height: 100%; overflow-x: hidden;"
                 background-color="rgb(48,65,86)"
                 text-color="#fff"
                 :collapse-transition="false"
                 :collapse="isCollapse"
        >
          <div style="height: 60px; line-height: 60px; text-align: center">
              <img src="../assets/logo.png" alt="" style="width: 20px; position: relative; top: 5px; margin-right: 5px">
              <b style="color: #fff" v-show="Textshow">后台管理系统</b>
          </div>

          <el-submenu index="1">

            </el-menu-item-group>
          </el-submenu>

        </el-menu>

      </el-aside>

      <el-container style="height: 100%">
        <el-header style="font-size: 18px; display:flex">
          <div style="flex: 1;font-size: 18px">
            <span :class="CollapseBtnClass" style="cursor: pointer" @click="Collapse"></span>
          </div>



          <el-dropdown style="width: 70px">

          </el-table>

          <div style="padding: 10px 0">
            <el-pagination
                    @size-change="handleSizeChange"
                    @current-change="handleCurrentChange"
                    :current-page="currentPage4"
                    :page-sizes="[5, 10, 15, 20]"
                    :page-size="10"
                    layout="total, sizes, prev, pager, next, jumper"
                    :total="400">
            </el-pagination>
          </div>
        </el-main>

      </el-container>

    </el-container>
</template>


<style>
  .el-header {
    background-color: #B3C0D1;
    color: #333;
    line-height: 60px;
  }
</style>

<script>
  export default {
    data() {
      const item = {
        date: '2016-05-02',
        name: '王小虎',
        address: '上海市普陀区金沙江路 1518 弄'
      };
      return {
        tableData: Array(10).fill(item),
        CollapseBtnClass: 'el-icon-s-fold',
        isCollapse: false,
        sideWidth: 200,
        Textshow:true
      }
    },
    methods:{
      Collapse(){
        this.isCollapse = !this.isCollapse
        if (this.isCollapse){
          this.sideWidth = 64
          this.CollapseBtnClass = 'el-icon-s-unfold'
          this.Textshow = false
        }else {
          this.sideWidth = 200
          this.CollapseBtnClass = 'el-icon-s-fold'
          this.Textshow = true
        }
      }
    }
  };
</script>

2. 创建全局样式global.css，可以将一些常见的操作写下

*{
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

.ml-5{
    margin-left: 5px;
}

.mr-5{
    margin-right: 5px;
}

.pd-10{
    padding: 10px 0;
}

3. 在main.js中引入样式

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import './assets/global.css';
