Question

So I have:

<li id="foo">
   <span> bar </span>
   <ul>
   <li>
      <span id="1234"></span>
   </li>
   <li>
      <span id="5678"></span>
   </li>

   </ul>
</li>

I need concatenate the span ids and make var foobar = “12345678”

P.S. I need start working from the top Li which has the id of “foo” since the span ids can be dynamic/unknown.

Thanks!

Try this:

var foobar = "";
$('#foo span[id]').each(function(){
   foobar += this.id
})
