iRSF快速简单易用的实现列表、排序、过滤功能

IRSF 是由javascript编写，iRSF快速简单易用的实现列表、排序、过滤功能(该三种操作以下简称为 RSF )。

iRSF由三个类组成。

iRSfsource 数据源iRSFFilter 过滤器iRSFSorter 排序器　　

iRSF 使用：

iRsf = new iRSF();iRsf.draw = function(data){//展现列表，data的结构为{PRoperty:[{data1},{data2}]},* property 可以自定义，由iRSFSource 指定。};//指定数据源iRsf.setSource({src:{items:[{id:1121,name:"dfsa"},{id:1122,name:"dfsa"}]},property:"items"});//添加过滤器iRsf.addFilter("id",function(row){return row.id==1121;});//设置排序iRsf.setSort(function(a,b){return a.id-b.id;});//执行，并重画列表 会调用iRsf.draw方法iRsf.records();

iRsf 源码：
