jQuery，找到父项 [英] JQuery, find parent

问题描述

<ul><li><div><div><span id="thisid"></span></div></div></li></ul>

$('#thisid').parent('li');

那显然是行不通的，但是我该如何获取li元素呢?我不想使用:

that obviously doesn't work, but how do I grab the li element? I don't want to use:

$('#this').parent().parent().parent();

我不想使用它，因为有可能只有一个div元素，而不是两个.在这种情况下，我将获取ul元素而不是li元素.

I don't want to use it, because it can happen that there is just one div element, instead of two. In this case I would grab the ul element instead of the li element.

推荐答案

$('#thisid').parents('li');
//                 ^ plural!

请注意，如果只希望祖先中的第一个<li>元素，则应使用closest():

Note that if you only want the first <li> element in the ancestry, you should use closest():

$('#thisid').closest('li');

// `closest()` is equivalent to (but performs better than)
$('#thisid').parents('li').eq(0);
$('#thisid').parents('li').first();
