Getting Layer Properties

[Light777]

I am trying to get the height or width or left or top of a layer that has not been explicitly set or has been set to a percentage.

i.e.

#DIV {position: absolute; width: 100%}

<div id="DIV">
</div>

I am changing the innerHTML of this layer and then trying to get the height so I can lay out the page without overlapping. When I use:

alert(document.getElementById("DIV").style.height);

I get the error message:

"style.height" is null or not an object.

Why is this happening?

Nevermind, I wrote the wrong alert. However, I'm not getting anything for style.height, as a string it would be "". When I use style.offsetHeight, I get an undefined error. Is there anyway around this?

u dont get style.height as "" as it is not set.

its document.getElementById(...).offsetHeight

offsetHeight is not a subset of style...
