无限滚动原理：无限滚动的实现原理就是当你在网页上的滚动条滚动到离网页底部一定长度的时候，触发某ajax函数（infinite-scroll内已经封装好）,往后台加载文件或者数据，又或者从外部引入静态html形式文件。
一个简单的实例
html页面代码如下
<!DOCTYPE HTML>
<html>
<head>
<title>无限瀑布流</title>
<style type="text/css">
.container{padding:20px;}
.box{margin-bottom:20px;float:left;width:220px;}
.box .image_box{width:100%;height:300px;background:#FCF;}
#infscr-loading{text-align:center;padding:10px;background:#000;opacity:0.8;filter:alpha(opacity=80);color:#FFF;}
#infscr-loading{position:fixed;bottom:0px;left:45%;z-index:9999;width:200px;}
</style>
