前言

&最近因为一些原因,没有更博客,昨天老师布置了一个作业,用vue实现增删改查功能,想想这也不难,就做一下试试吧。
因为自己写的样式没有别人做的好,因此我想用现成的UI框架,一直也没用过Element,就干脆趁机学一下吧。

实验步骤

首先引入一下element的css以及js

<!-- 引入样式 -->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css" rel="external nofollow" rel="external nofollow" >
<!-- 引入组件库 -->
<script src="/UploadFiles/2021-04-02/index.js">

然后引入需要用到的vue相关的js文件

<script src="/UploadFiles/2021-04-02/vue.js">

下面说一下HTML结构

<div id="app">
  <h1>职位的增删改查</h1>
  <div class="head">
    <el-row :gutter="20">
      <el-col :span="6">
        <el-input v-model="userInfo.name" placeholder="请输入你的公司名"></el-input>
      </el-col>
      <el-col :span="6">
        <el-input v-model="userInfo.position" placeholder="请输入你的职位"></el-input>
      </el-col>
      <el-col :span="6">
        <el-input v-model="userInfo.major" placeholder="请输入你的专业"></el-input>
      </el-col>
      <el-col :span="6">
        <el-input v-model="userInfo.number" placeholder="请输入数量"></el-input>
      </el-col>
    </el-row>
    <el-button type="primary" @click="addUser" class="add-btn" plain>添加信息</el-button>
  </div>
  <!-- 主体内容 -->
  <div class="body">
    <template>
      <el-table :data="tableData" style="width: 100%">
        <el-table-column label="序号" width="180"><template slot-scope="scope"> {{scope.$index + 1 }} </template></el-table-column>
        <el-table-column prop="name" label="公司名" width="180"></el-table-column>
        <el-table-column prop="position" label="职位"></el-table-column>
        <el-table-column prop="major" label="专业"></el-table-column>
        <el-table-column prop="number" label="数量"></el-table-column>
        <el-table-column prop="birthday" label="操作">
          <template slot-scope="scope">
            <el-button type="primary" icon="el-icon-edit" @click="editUser(scope.row,scope.$index)" circle></el-button>
            <el-button type="danger" icon="el-icon-delete" @click="delUser(scope.$index)" circle></el-button>
          </template>
        </el-table-column>
      </el-table>
    </template>
  </div>
  <!-- 编辑框 -->
  <el-dialog title="编辑用户信息" :visible.sync="dialogVisible" width="30%" :before-close="handleClose">
    <div>
      <el-form ref="form" :model="editObj" label-width="80px">
        <el-form-item label="公司名"><el-input v-model="editObj.name"></el-input></el-form-item>
        <el-form-item label="职位"><el-input v-model="editObj.position"></el-input></el-form-item>
        <el-form-item label="专业"><el-input v-model="editObj.major"></el-input></el-form-item>
        <el-form-item label="数量"><el-input v-model="editObj.number"></el-input></el-form-item>
      </el-form>
    </div>
    <span slot="footer" class="dialog-footer">
      <el-button @click="dialogVisible = false">取 消</el-button>
      <el-button type="primary" @click="confirm">确 定</el-button>
    </span>
  </el-dialog>
</div>

这一段是element的表单以及编辑等样式 ,其中添加了一些click操作 后面需要用到

加上基础的样式

 <style>
    #app{
      width:1024px;
      margin: 0 auto; 
    }
    .add-btn{
      margin-top: 20px;
      width: 100%;
    }
    .body{
      margin-top:20px;
    }
  </style>

现在页面的基本样式就做好了,如下图所示:

VUE+Element实现增删改查的示例源码

下面开始写vue代码,对各个功能进行处理操作
了解过vuejs的应该知道这样的结构 data里面填写我们获取的数据 一些规则,定义一些变量 ,在methods进行我们的操作。

new Vue({
  el: '#app',
    data:{},
    methods:{}
})
data: function(){
        return{
          userInfo:{ 
            name:'',
            position: '',
            major: '',
            number: '',
          },
          tableData: [{
            name:'互联网+学院',
            position: '专职教师',
            major: '对外贸易',
            number: '2',
          },{
            name:'徐州重工',
            position: '工厂车研发部工程师',
            major: '精密机械制造',
            number: '12',
          },{
            name:'北京青码科技',
            position: '前端开发工程师',
            major: 'Vue、React',
            number: '4',
          }
          ],
          dialogVisible: false, 
          editObj:{
            name:'',
            position: '',
            major: '',
            number: '',
          },
          userIndex:0,
        }
      },

接下来我们添加methods

  • "htmlcode">
     methods:{
           //添加
            addUser(){
              if(!this.userInfo.name){
                this.$message({
                  message: '请输入你的公司名!',
                  
                });
                return;
              }
              if(!this.userInfo.position){
                this.$message({
                  message: '请输入你的职位!',
                  type: 'warning'
                });
                return;
              }
              if (!this.userInfo.major) {
                this.$message({
                  message: '请输入你的专业!',
                  type: 'warning'
                });
                return;
              }
              if (!this.userInfo.number) {
                this.$message({
                  message: '请输入数量!',
                  type: 'warning'
                });
                return;
              }
              this.tableData.push(this.userInfo);
              this.userInfo = { 
                name:'',
                position: '',
                major: '',
                number: '',
              };
            },
    
            //删除
            delUser(idx){
              this.$confirm('确认删除此用户信息?')
                .then(_ => {
                  this.tableData.splice(idx, 1);
                })
                .catch(_ => {});
            },
            //编辑
            editUser(item,idx){
              this.userIndex = idx;
              this.editObj = {
                name: item.name,
                position: item.position,
                major: item.major,
                number: item.number,
              };
              this.dialogVisible = true;
            },
    
            handleClose(){
              this.dialogVisible = false;
            },
    
            confirm(){
              this.dialogVisible = false;
              Vue.set(this.tableData, this.userIndex, this.editObj);
                }
              },
            })

    总结:
