     (/div)

....................... it goes on untill there is one more level added. the thing is that i want to get the id of child ul when the parent span is selected. get ul1 as result

Answer 1

If the UL is a descendant of the span (which is how I understand this problem), you can do this:

$("span").click(function() {
    alert($(this).find("ul").attr("id"));
});

If the UL is always the very next sibling, you can use .next :

$(this).next("ul").attr("id");

Answer 2

When you select it you can grab it, for example:

$("span").click(function() {
  var ulID = $(this).siblings("ul").attr("id");
});

In your case it appears to be a sibling, so .siblings() would be appropriate.

Answer 3

for my it looks like you want to find the first ul as a child of a parent ul .

So try this:

$( 'ul' ).click( function() {
  console.debug( $(this).find('ul').attr('id') );
});
