jQuery WeUI 是专为微信公众账号开发而设计的一个简洁而强大的UI库,包含全部WeUI官方的CSS组件,并且额外提供了大量的拓展组件,丰富的组件库可以极大减少前端开发时间。
jQuery WeUI 的最大特点是它只提供UI组件,并不会对项目所使用的框架和其他库有任何的限制,几乎可以在任何环境下使用。无论你的项目是基于jQuery,还是 React, Angular, Vue, 你都会发现 jQuery WeUI 能非常方便的和他们结合使用。既是你的项目是一个有很悠久历史的老项目,也几乎可以做到拿来即用。
weui框架暂时只有css文件,并没有js文件实现其功能,我在其html+css后面增加了js实现其功能,为大家提供方便,也为自己保存记录。

补充说明上述代码中引用以下的这四个文件可以到http://jqweui.com这个weui的官网去下载
<link rel="stylesheet" href="weui.min.css" rel="external nofollow" rel="external nofollow" /> <link rel="stylesheet" href="jquery-weui.css" rel="external nofollow" rel="external nofollow" /> <script type="text/javascript" src="jquery-2.1.4.js"> </script><script type="text/javascript" src="jquery-weui.js"></script>
