如何删除< li>来自< ul>由ID?

问题描述：

我有:

<ul id="ulId">
    <li id="firstli">
    </li>
    <li id="secondli">
    </li>
</ul>

并且我正在尝试删除secondli.

这是我根据一些阅读尝试过的.

This is what I have tried based on some reading.

$('#ulId secondli').remove();

和

$('#ulId > secondli').remove();

，但是这两种方法不起作用.有什么建议吗?

but these 2 methods did not work. Any suggestions?

答

尝试一下:

$('#secondli').remove();

在jQuery中，您引用的元素的ID前面带有#.请参见 http://api.jquery.com/id-selector/

In jQuery, you refer to the ID of an element with a # in front of it. See http://api.jquery.com/id-selector/
