jQuery child of clicked element

Question

Hi,

I've got a list of links which have a click event attached to them, I need to get the ID from the child A link. So in the example below if I clicked the first list element I'd need google retuned.

I've tried '$this a' but can't quite work out the syntax.

jQuery:

$("ul li").click(function(event){
$("input").val($(this).html());     
  }
);



html:
<ul>
    <li><a href="http://www.google.com" id="google">Google</a>
</ul>

Answer 1

I don't see the sample HTML but

$(this).find('a:first').attr('id')

would do it (fix a:first selector if it's not what you meant)

this refer to the element that fired your event

Answer 2

You could use the children method:

$(this).children('a')[0].attr('id');

I'm not sure about the syntax, but something like this should work.

Answer 3

Hey Tom

To make your code a little neater, lets bind triggers with functions like so: (i suggest you give your UL an ID so it is specific to only elements within that UL)

$('ul li').bind('click', getAnchorId);

The function that is called (getAnchorId) gets the ID attribute of the children element (a) of the clicked element (ul li) and applies it to a variable (anchorId), and to show its getting the correct info I put the result in an alert.

function getAnchorId() {
    var anchorId = $(this).children('a').attr('id');
    alert(anchorId);
}

Now u can do what ever u wish with that variable :)

hope this helps :)
