Get ID of first LI of UL with jQuery

Question

<ul id="someList">
<li id="listItem1">List 1</li>
<li id="listItem2">List 2</li>
</ul>

Maybe I need to brush up on my selectors, but how would you grab the first ID of ul#someList?

Also if I'm prepending LI's to ul#someList, will I need to grab the first LI's ID in a different way?

Answer 1

$('ul#someList li:first') is what you're looking for.

Answer 2

Your best bet is to use the first selector.

var id = $("ul#someList li:first").attr("id");

or

var id = $("ul#someList li:first").get(0).id;
