Aui-core实现模拟MVC单列表绝对定位版瀑布流js特效

Aui-core实现模拟MVC单列表绝对定位版瀑布流js特效，浏览更多瀑布流特效代码

主要用了3个function：

1、controller

2、view

3、model

 

这3个方法是面向对象编程的MVC模式，有兴趣的网友认真看一下哦，对大家的学习会有帮助的啦。。。

 

唯一不足之处就是加载数据的时候一定要部署到服务端才可以看到效果，大家使用的时候可以自定义加载数据功能。

<link href="css/base.css" type="text/css"  rel="stylesheet" media="all" />
<style>
#demo { width:735px; height:auto; position:relative; z-index:0; }
#demo li { margin:5px; background:#fff; border:5px solid #fff; position:absolute; left:0; top:0; z-index:1; }
#demo li p { line-height:50px; text-align:center; }
.hidden { overflow:hidden; }
#loading { background:#fff url(images/loading.gif) no-repeat 10px center; height:50px; line-height:50px; width:140px; text-align:center; position:absolute; left:0; top:0; z-index:2; padding-left:30px; padding-right:5px; border:2px #aaa solid; display:none; }
</style>
