Question

So I have

<li>
<span id="foobar"> abc </span>
</li>

I now have li as an nodeObject. I could get "LI" by using li.nodeName.

Now how could I get "foobar" out of li which is an ID of a span inside it.

I tried:

 $node = li;
 alert($node>span.Id);

but not working, thanks!

Answer 1

You can do it like this…

alert(li.firstElementChild.id);

or this…

alert(li.getElementsByTagName('span')[0].id);

or this…

alert(li.children[0].id);
