如何在我的 jscript 中:

if(tr.not('.details-link')){

我可以不理会这样的td，因为我没有 class =Details-link 吗？现在我的代码无法工作......

只需跳过编辑我的代码，这样如果 tr 没有类，我会做一些事情......如何做到这一点？

更新我需要这样做:<强> http://jsfiddle.net/zvKSc/8/

删除重复项(通过小写的1,2,5列和删除空格必须相等...)，但在页面上留下这样的tr，其中在td之一中我有类详细信息链接...所以在 fiddle 中从三个我必须首先删除，并留下第二个和第三个tr

Answer 1

if(!$('tr').hasClass('details-link')) {

// code to execute if tr does not have class

}
