Find the element before and after a specific element

问题

I have a list with links I use with tabs. It looks like this:

<ul>
    <li><a href="#">First tab</a></li>
    <li><a href="#">Second tab</a></li>
    <li class="active"><a href="#">Active tab</a></li>
    <li><a href="#">Fourth tab</a></li>
    <li><a href="#">Fifth tab</a></li>
</ul>

How can I find the list element before and after the active tab? (In this case, the second and fourth tab).

Tried using find, with no success :(

回答1:

$("li.active").next();

and

$("li.active").prev();
