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:

<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。

</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。文章来源:https://www.toymoban.com/news/detail-824882.html
