用Javascript进行简单的Table点击排序

2008-05-07 19:15 435 查看
闲着没事,随便写了个简单的Table排序的js,大家有兴趣的看看,有需要的就拿去吧.废话不说了,大家看代码吧,最下面是效果,着急的就直接往下拉好了.新发现一个bug:10比2小,原因是sort默认是按ascii排序的,已修复该问题.

旧版DEMO下载

最新DEMO下载 [修复了一些已知的问题,结合网友的回复优化了一些代码,用法跟原来要样]

html代码[可以不看,跟html没什么关系.]:

//Explain : 使Table可以点击排序.
/*使用说明 :
方法1:
new TableSorter("tb1");
效果:
id为tb1的table的第一行任意单元格都可以点击进行排序.
方法2:
new TableSorter("tb1", 0, 1, 3);
效果:
id为tb1的table的第一行0,1,3单元格可以进行点击排序.
