Toggling an Element BG

[abcdefGARY]

Hello, I found this useful javascript snippet that helps me toggle the background color of an element:

<script type="text/javascript">
function toggleBgColor( elem )
{
	var style2 = elem.style;
	style2.backgroundColor = style2.backgroundColor? "":"#FFFF00";
}
</script>

with this...

<div onclick="javascript:toggleBgColor( this );">testing</div>
<div id="testing-element">change this color</div>

the script can only change the bg-color of the current div (the "testing" text), however, I'd like to change the bg-color of a specific div element (for example, the "testing-element").

I think I need to add "GetElementbyID" or whatever to the script/code, but I'm not an expert on this field. any help would be greatful.

thanks.
