一、Element概述
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，用于快捷构建网页
组件：组成网页的部件，例如 超链接、按钮、图片、表格等等~
官网：组件 | Element
https://element.eleme.cn/#/zh-CN/component/installation
二、Element入门案例
1、引入Element的css、js文件和Vue.js
<script src="js/vue.js"></script> <script src="element-ui/lib/index.js"></script> <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css">
2、创建Vue核心对象
<script> new Vue({ el: "#app" }) </script>
3、官网复制Element组件代码
Element按钮代码示例：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <div id="app"> <el-row> <el-button>默认按钮</el-button> <el-button type="primary">主要按钮</el-button> <el-button type="success">成功按钮</el-button> <el-button type="info">信息按钮</el-button> <el-button type="warning">警告按钮</el-button> <el-button type="danger">危险按钮</el-button> </el-row> <el-row> <el-button plain>朴素按钮</el-button> <el-button type="primary" plain>主要按钮</el-button> <el-button type="success" plain>成功按钮</el-button> <el-button type="info" plain>信息按钮</el-button> <el-button type="warning" plain>警告按钮</el-button> <el-button type="danger" plain>危险按钮</el-button> </el-row> <el-row> <el-button round>圆角按钮</el-button> <el-button type="primary" round>主要按钮</el-button> <el-button type="success" round>成功按钮</el-button> <el-button type="info" round>信息按钮</el-button> <el-button type="warning" round>警告按钮</el-button> <el-button type="danger" round>危险按钮</el-button> </el-row> <el-row> <el-button icon="el-icon-search" circle></el-button> <el-button type="primary" icon="el-icon-edit" circle></el-button> <el-button type="success" icon="el-icon-check" circle></el-button> <el-button type="info" icon="el-icon-message" circle></el-button> <el-button type="warning" icon="el-icon-star-off" circle></el-button> <el-button type="danger" icon="el-icon-delete" circle></el-button> </el-row> </div> <script src="js/vue.js"></script> <script src="element-ui/lib/index.js"></script> <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css"> <script> new Vue({ el: "#app" }) </script> </body> </html>
执行结果：
三、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
Layout布局代码示例：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .el-row { margin-bottom: 20px; } .el-col { border-radius: 4px; } .bg-purple-dark { background: #99a9bf; } .bg-purple { background: #d3dce6; } .bg-purple-light { background: #e5e9f2; } .grid-content { border-radius: 4px; min-height: 36px; } .row-bg { padding: 10px 0; background-color: #f9fafc; } </style> </head> <body> <div id="app"> <el-row> <el-col :span="24"> <div class="grid-content bg-purple-dark"></div> </el-col> </el-row> <el-row> <el-col :span="12"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="12"> <div class="grid-content bg-purple-light"></div> </el-col> </el-row> <el-row> <el-col :span="8"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="8"> <div class="grid-content bg-purple-light"></div> </el-col> <el-col :span="8"> <div class="grid-content bg-purple"></div> </el-col> </el-row> <el-row> <el-col :span="6"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="6"> <div class="grid-content bg-purple-light"></div> </el-col> <el-col :span="6"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="6"> <div class="grid-content bg-purple-light"></div> </el-col> </el-row> <el-row> <el-col :span="4"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="4"> <div class="grid-content bg-purple-light"></div> </el-col> <el-col :span="4"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="4"> <div class="grid-content bg-purple-light"></div> </el-col> <el-col :span="4"> <div class="grid-content bg-purple"></div> </el-col> <el-col :span="4"> <div class="grid-content bg-purple-light"></div> </el-col> </el-row> </div> <script src="js/vue.js"></script> <script src="element-ui/lib/index.js"></script> <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css"> <script> new Vue({ el: "#app" }) </script> </body> </html>
执行结果：
Container布局容器：
用于布局的容器组件，方便快速搭建页面的基础结构
Container布局容器代码示例：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .el-header { background-color: #B3C0D1; color: #333; line-height: 60px; } .el-aside { color: #333; } </style> </head> <body> <div id="app"> <el-container style="height: 500px; border: 1px solid #eee"> <el-aside width="200px" style="background-color: rgb(238, 241, 246)"> <el-menu :default-openeds="['1', '3']"> <el-submenu index="1"> <template slot="title"><i class="el-icon-message"></i>导航一</template> <el-menu-item-group> <template slot="title">分组一</template> <el-menu-item index="1-1">选项1</el-menu-item> <el-menu-item index="1-2">选项2</el-menu-item> </el-menu-item-group> <el-menu-item-group title="分组2"> <el-menu-item index="1-3">选项3</el-menu-item> </el-menu-item-group> <el-submenu index="1-4"> <template slot="title">选项4</template> <el-menu-item index="1-4-1">选项4-1</el-menu-item> </el-submenu> </el-submenu> <el-submenu index="2"> <template slot="title"><i class="el-icon-menu"></i>导航二</template> <el-menu-item-group> <template slot="title">分组一</template> <el-menu-item index="2-1">选项1</el-menu-item> <el-menu-item index="2-2">选项2</el-menu-item> </el-menu-item-group> <el-menu-item-group title="分组2"> <el-menu-item index="2-3">选项3</el-menu-item> </el-menu-item-group> <el-submenu index="2-4"> <template slot="title">选项4</template> <el-menu-item index="2-4-1">选项4-1</el-menu-item> </el-submenu> </el-submenu> <el-submenu index="3"> <template slot="title"><i class="el-icon-setting"></i>导航三</template> <el-menu-item-group> <template slot="title">分组一</template> <el-menu-item index="3-1">选项1</el-menu-item> <el-menu-item index="3-2">选项2</el-menu-item> </el-menu-item-group> <el-menu-item-group title="分组2"> <el-menu-item index="3-3">选项3</el-menu-item> </el-menu-item-group> <el-submenu index="3-4"> <template slot="title">选项4</template> <el-menu-item index="3-4-1">选项4-1</el-menu-item> </el-submenu> </el-submenu> </el-menu> </el-aside> <el-container> <el-header style="text-align: right; font-size: 12px"> <el-dropdown> <i class="el-icon-setting" style="margin-right: 15px"></i> <el-dropdown-menu slot="dropdown"> <el-dropdown-item>查看</el-dropdown-item> <el-dropdown-item>新增</el-dropdown-item> <el-dropdown-item>删除</el-dropdown-item> </el-dropdown-menu> </el-dropdown> <span>王小虎</span> </el-header> <el-main> <el-table :data="tableData"> <el-table-column prop="date" label="日期" width="140"> </el-table-column> <el-table-column prop="name" label="姓名" width="120"> </el-table-column> <el-table-column prop="address" label="地址"> </el-table-column> </el-table> </el-main> </el-container> </el-container> </div> <script src="js/vue.js"></script> <script src="element-ui/lib/index.js"></script> <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css"> <script> new Vue({ el: "#app", 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(20).fill(item) } } }) </script> </body> </html>
执行结果：
