How to determine the size of an opened window

[wood_tah]

I need to find out how to determine the size of an open window so that I can set the size of a div. I want the div to be full screen, but without any scroll bars. I have tried using screen.availHeight and screen.availWidth, but they return the same values no matter what the size of the window is. I thought there was a property that returned this, but I can't seem to find it. I need a cross-browser solution (mainly IE5.5+ and NS6+).

Try this:

//  Window dimensions:  
if (window.innerWidth)
	theWidth=window.innerWidth;
else if (document.documentElement && document.documentElement.clientWidth)
	theWidth=document.documentElement.clientWidth;
else if (document.body)
	theWidth=document.body.clientWidth;

if (window.innerHeight)
	theHeight=window.innerHeight;
else if (document.documentElement && document.documentElement.clientHeight)
	theHeight=document.documentElement.clientHeight;
else if (document.body)
	theHeight=document.body.clientHeight;

Hi, i need something like that.
It's been a long time ago since you post the code. What can I use for FF2 and IE6+??

Thanks!!!!

That code works with IE5+ and FF1+.

You can cut it back by getting rid of the document.body tests if all your pages have a strict doctype.

Hi. Thanks for reply.

I'm using Quirks Mode. I work on a 4GL wich generates the web pages... That's why I'm a web developer rookie after all.

The pages doesn't have a doctype.
