Jquery 父子选择器

Question

我有下面的 html 结构，我试图选择包含文本“相关列表项：”的行。

我的 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

我更喜欢给tr一个id，然后通过id删除tr。
$('#trid').remove();

Answer 3

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