Jquery父子選擇器

Question

我有下面的html結構，我試圖選擇包含文本'相關列表項'的行。我們的jquery如下： $（'＃WebPartWPQ3> table（eq：2）> tbody> tr> td> table> tbody> tr：last'）。remove（）; 但不工作...

Answer 1

$('.ms-formlabel').last().children().remove(); 

Answer 2

我寧願給一個ID，TR和ID刪除TR。 $('#trid').remove();

Answer 3

$('#WebPartWPQ3').find('Related list item').closest('tr').remove();
