1、什么是Element
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
Element 提供了很多组件(组成网页的部件)供我们使用。例如 超链接、按钮、图片、表格等等~
如下图左边的是我们编写页面看到的按钮,上图右边的是 Element 提供的页面效果,效果一目了然。
我们学习 Element 其实就是学习怎么从官网拷贝组件到我们自己的页面并进行修改,官网网址是
https://element.eleme.cn/#/zh-CN
进入官网能看到如下页面
接下来直接点击 组件
,页面如下
2、Element快速入门
使用流程:
-
创建页面,并在页面引入Element 的css、js文件 和 Vue.js
<script src="vue.js"></script> <script src="element-ui/lib/index.js"></script> <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css">
-
.创建Vue核心对象
Element 是基于 Vue 的,所以使用Element时必须要创建 Vue 对象
<script>new Vue({el:"#app"}) </script>
-
官网复制Element组件代码
在左菜单栏找到 Button 按钮
,然后找到自己喜欢的按钮样式,点击 显示代码
,在下面就会展示出对应的代码,将这些代码拷贝到我们自己的页面即可。
代码演示:
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>容器布局</title><script src="../js/vue.js"></script><link rel="stylesheet" href="../element-ui/lib/theme-chalk/index.css"><script src="../element-ui/lib/index.js"></script></head>
<body><div id="div"><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>
</body>
<script>new Vue({el:"#div"});
</script>
</html>
3、Element布局
Element 提供了两种布局方式,分别是:
- Layout 布局
- Container 布局容器
3.1、 Layout 局部
通过基础的 24 分栏,迅速简便地创建布局。也就是默认将一行分为 24 栏,根据页面要求给每一列设置所占的栏数。
在左菜单栏找到 Layout 布局
,然后找到自己喜欢的按钮样式,点击 显示代码
,在下面就会展示出对应的代码,显示出的代码中有样式,有html标签。将样式拷贝我们自己页面的 head
标签内,将html标签拷贝到 <div id="app"></div>
标签内。
整体页面代码如下:
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>基础布局</title><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"><style>.el-row {margin-bottom: 20px;&:last-child {margin-bottom: 0;}}.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="div"><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>
</body>
<script>new Vue({el:"#div"});
</script>
</html>
3.2、容器布局
用于布局的容器组件,方便快速搭建页面的基本结构:
<el-container>
:外层容器。当子元素中包含 <el-header>
或 <el-footer>
时,全部子元素会垂直上下排列,否则会水平左右排列。
<el-header>
:顶栏容器。
<el-aside>
:侧边栏容器。
<el-main>
:主要区域容器。
<el-footer>
:底栏容器。
如下图是官网提供的 Container 布局容器实例:
该效果代码中包含了样式、页面标签、模型数据。将里面的样式 <style>
拷贝到我们自己页面的 head
标签中;将html标签拷贝到 <div id="app"></div>
标签中,再将数据模型拷贝到 vue
对象的 data()
中。
整体页面代码如下:
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>容器布局</title><script src="../js/vue.js"></script><link rel="stylesheet" href="../element-ui/lib/theme-chalk/index.css"><script src="../element-ui/lib/index.js"></script><style>.el-header, .el-footer {background-color: #B3C0D1;color: #333;text-align: center;line-height: 60px;}.el-aside {background-color: #D3DCE6;color: #333;text-align: center;line-height: 200px;}.el-main {background-color: #E9EEF3;color: #333;text-align: center;line-height: 160px;}body > .el-container {margin-bottom: 40px;}.el-container:nth-child(5) .el-aside,.el-container:nth-child(6) .el-aside {line-height: 260px;}.el-container:nth-child(7) .el-aside {line-height: 320px;}</style>
</head>
<body><div id="div"><el-container><el-header>Header</el-header><el-main>Main</el-main></el-container><el-container><el-header>Header</el-header><el-main>Main</el-main><el-footer>Footer</el-footer></el-container><el-container><el-aside width="200px">Aside</el-aside><el-main>Main</el-main></el-container><el-container><el-header>Header</el-header><el-container><el-aside width="200px">Aside</el-aside><el-main>Main</el-main></el-container></el-container><el-container><el-header>Header</el-header><el-container><el-aside width="200px">Aside</el-aside><el-container><el-main>Main</el-main><el-footer>Footer</el-footer></el-container></el-container></el-container><el-container><el-aside width="200px">Aside</el-aside><el-container><el-header>Header</el-header><el-main>Main</el-main></el-container></el-container><el-container><el-aside width="200px">Aside</el-aside><el-container><el-header>Header</el-header><el-main>Main</el-main><el-footer>Footer</el-footer></el-container></el-container></div>
</body>
<script>new Vue({el:"#div"});
</script>
