Hello everyone, I have a problem with my javascript, im new to it so please bear with me.

I have a function which looks like

CODE

function mainLeftElements(){
    var containerDiv = document.getElementById('mainLeft');
    var elems = containerDiv.childNodes;
    alert(elems.length);
}


which for a div declared like so

CODE

<div id = 'mainLeft'></div>


alerts me it has a length of 1, trying to work out what the element is (thinking it might be a blank text element or something, maybe the id attribute also??) by using

CODE

elems[0].tagName


and

CODE

elems[0].id


i get confused as they both return 'undefined', so what is it?

Thanks for any help you can offer me,

Rackham
