ElementUI
笔记目录:(https://www.cnblogs.com/wenjie2000/p/16378441.html)
-
Element:是饿了么公司前端开发团队提供的一套基于Vue的网站组件库,用于快速构建网页
-
组件:组成网页的部件,例如超链接、按钮、图片、表格等等~
-
自己完成的按钮
-
Element 提供的按钮
-
Element官网:https://element-plus.org/zh-CN/#/zh-CN(基于 Vue 3)
https://element.eleme.cn/#/zh-CNListener(基于 Vue 2)
我后面用的都是基于vue2的。如果想使用基于vue3的版本,可以去看官网,也有官方教程。
Element快速入门
-
引入Element的css、js文件和Vue.js
<!-- 引入vue2 --> <script src="https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"></script> <!-- 引入样式 --> <link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css"> <!-- 引入组件库 --> <script src="https://unpkg.com/element-ui/lib/index.js"></script>
-
创建Vue核心对象
new Vue({ el: "#app", })
-
官网复制Element组件代码
例如:https://element.eleme.cn/2.15/#/zh-CN/component/button
将代码放到div中(<style>部分的代码需要放在div外面),页面就能正常显示了。至于复制的代码是什么意思,不需要看懂,这都是element自己定义的标签,会用会修改就行。有不会的部分就去官网查(各项参数说明在各个组件页面的最下面)
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Title</title> <script src="https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"></script> <!-- 引入样式 --> <link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css"> <!-- 引入组件库 --> <script src="https://unpkg.com/element-ui/lib/index.js"></script> </head> <body> <div id="app"> <el-row> ......//这里内容比较多,自己去官网复制,后面也是 </el-row> </div> <script> new Vue({ el: "#app", }) </script> </body> </html>
Element布局
-
Element中有两种布局方式:
-
Layout布局:通过基础的24分栏,迅速简便地创建布局
-
Container布局容器:用于布局的容器组件,方便快速搭建页面的基本结构
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <!-- 引入vue2 --> <script src="https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"></script> <!-- 引入样式 --> <link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css"> <!-- 引入组件库 --> <script src="https://unpkg.com/element-ui/lib/index.js"></script> <style> ......//注意style部分别放在div中 </style> </head> <body> <div id="app"> ...... </div> <script> new Vue({ el: "#app", ...... }) </script> </body> </html>

Element 组件
最终要实现以下页面内容:(要好好利用官网中现成的东西来进行改写)
