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();
