Get id of first UL LI using jQuery

Question

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

Maybe I need to clear my selectors, but how would you grab the first ul # someList id?

Also, if I add LI to ul # someList, will I need to capture the first LI identifier in a different way?

Answer 1

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

Answer 2

Best use first selector

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

or

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

Answer 3

This may be another solution:

 $('#someList li:nth-child(1)').attr("id"); 

Answer 4

Try it ****. slice (start, [end]) **** `

 <ul> <li id='l1'>list item 1</li> <li id='l2'>list item 2</li> <li id='l3'>list item 3</li> <li id='l4'>list item 4</li> <li id='l5'>list item 5</li> </ul> $('li').slice(2).attr('id');
