Try this:
尝试这个：
$('#secondli').remove();
In jQuery, you refer to the ID of an element with a #in front of it. See http://api.jquery.com/id-selector/
在 jQuery 中，您引用元素的 ID，并#在它前面加上。见http://api.jquery.com/id-selector/

This will work for you
这对你有用
$('#secondli').remove();
回答by Zach Shallbetter
$('#ulId #secondli').remove();
$('#ulId #secondli').remove();
Select the container #ulIdand then the list item #secondli. You had forgotten to add the ID tag before the second li.
选择容器#ulId，然后选择列表项#secondli。您忘记在第二个 li 之前添加 ID 标签。
回答by pingle60
You need to add a space between the select the li element,
您需要在 select li 元素之间添加一个空格，
$('#second li').remove(); // when referencing by id
or
或者
$(".second li").remove(); // when referencing by class
回答by nOcTIlIoN
if you want remove an <li>with ID try :
如果你想删除一个<li>带有 ID 的尝试：
$('#yourlist #yourli').remove();
$('#yourlist #yourli').remove();
otherwise, if you would remove an <li>based on the content you can use :
否则，如果您要删除<li>基于您可以使用的内容：
$('#yourlist li:contains("TextToRemove")').remove();
$('#yourlist li:contains("TextToRemove")').remove();
