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.$index)" circle></el-button> </template> </el-table-column> </el-table> </template> </div> <!-- 编辑框 --> <el-dialog title="编辑用户信息" :visible.sync="dialogVisible" width="30%" :before-close="handleClose"> <div> <el-form ref="form" :model="editObj" label-width="80px"> <el-form-item label="公司名"><el-input v-model="editObj.name"></el-input></el-form-item> <el-form-item label="职位"><el-input v-model="editObj.position"></el-input></el-form-item> <el-form-item label="专业"><el-input v-model="editObj.major"></el-input></el-form-item> <el-form-item label="数量"><el-input v-model="editObj.number"></el-input></el-form-item> </el-form> </div> <span slot="footer" class="dialog-footer"> <el-button @click="dialogVisible = false">取 消</el-button> <el-button type="primary" @click="confirm">确 定</el-button> </span> </el-dialog> </div>这一段是element的表单以及编辑等样式 ,其中添加了一些click操作 后面需要用到
加上基础的样式
<style> #app{ width:1024px; margin: 0 auto; } .add-btn{ margin-top: 20px; width: 100%; } .body{ margin-top:20px; } </style>现在页面的基本样式就做好了,如下图所示:
下面开始写vue代码,对各个功能进行处理操作
了解过vuejs的应该知道这样的结构 data里面填写我们获取的数据 一些规则,定义一些变量 ,在methods进行我们的操作。new Vue({ el: '#app', data:{}, methods:{} })data: function(){ return{ userInfo:{ name:'', position: '', major: '', number: '', }, tableData: [{ name:'互联网+学院', position: '专职教师', major: '对外贸易', number: '2', },{ name:'徐州重工', position: '工厂车研发部工程师', major: '精密机械制造', number: '12', },{ name:'北京青码科技', position: '前端开发工程师', major: 'Vue、React', number: '4', } ], dialogVisible: false, editObj:{ name:'', position: '', major: '', number: '', }, userIndex:0, } },接下来我们添加methods
- "htmlcode">
methods:{ //添加 addUser(){ if(!this.userInfo.name){ this.$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:
"htmlcode">
