Question

Select child element of the current element

Asked by: Hube02

I'm trying to select the child element of the current element.

What I have:

"this" holds the current element which is a <li> element so if I do alert(this); what I get is:

[object HTMLLIElement]

What I want to get is The ul elements that are children of this li (not grandchildren so the normal selector would be li>ul)

How?

Hopefully this makes sense, if not let me know how I can clear it up...

@wktang83:I should have been more specific, I am looking for a JQuery solution.

@sh0e: This seems to alert all decedent <ul>'s of the <li> and not just the chlidren.

so, for example I have this

<ul id="wft">
  <li>This is the LI that is in the variable "this"
    <ul>     <!-- I want to get this u lelement -->
      <li>I do no want to get the child ul elements of this li
        <ul><li>I should not get this</li></ul>
      </li>
    </ul>
  </li>
</ul>
     

 

by: Hube02Posted on 2008-10-07 at 12:13:07ID: 22662594

@sh0e: Missed your second comment,, this seems to work to get each of the li elements and the each child ul elements.

Now I'm going to have more questions........

	$('ul#RightSliderMenu').each(function(){
		$(this).children('li').each(function(){
			$(this).children('ul').each(function(){
				alert(this);
			});
		});
	});

tagName can be undefined for textnodes use the following instead :)

function getChildLists(li)
{
	var ret = [];
	for(i in li.childNodes)
		if(li.childNodes[i].tagName && li.childNodes[i].tagName.toLowerCase() == "ul")
			ret.push(li.childNodes[i]);
	return ret;
}
