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 = "https://unpkg.com/element-ui/lib/index.js" ></ script > |
然后引入需要用到的vue相关的js文件

<script src= "https://cdn.jsdelivr.net/npm/vue/dist/vue.js" ></script> |
下面说一下HTML结构

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
- addUser() 是添加数据
- delUser()是删除数据
- editUser()是编辑数据
- handleClose()是是否弹出编辑框
- confirm()是确认信息并且传数据到表格中
在增加模块中,我做了信息判断,如果是信息是空就会弹出提示框,显示信息不能为空,
在删除模块中,点击可以删除一行信息
在修改模块中,会先将原本的信息拿到,然后再修改你需要修改的信息。

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:
通过这次练习,让我知道了Element框架是怎么使用的,Element框架写代码做样式的确方便,以后有什么要求低的作业可以拿来使用,目前的我毕竟还是一个学生,我还是需要多锻炼写代码,手写样式的能力。
最后: 附整个项目的源代码,本项目仅供学习交流。
