如何在我的jscript中：
if(tr.not('.details-link')){
我可以单独留下这样的td，我没有class = details-link？ 现在我的代码无效......
只是跳过编辑我的代码，这样如果tr没有课程，我会做点什么......怎么做？
UPD 我需要这样做： 的 http://jsfiddle.net/zvKSc/8/
删除重复项（1,2,5列通过小写和删除空格必须相等...），但留在页面上这样的tr，其中一个td我有类详细信息 - 链接...所以在小提琴从三个我必须先删除，并留下第二和第三tr
答案 0 :(得分：1)
if(!$('tr').hasClass('details-link')) {
// code to execute if tr does not have class
}
