communication *.js file and IE

[yavuz]

If I write javascript in the HTML, then I can get the width of the document with document.offsetWidth. I want write a generic .js file, but then I can't get the size of the document with document.offsetWidth. Is there any way to do that?

Thanks.

Try using screen.width perhaps?

But I need the inner area of IE.
The problem is that document.offsetWidth works if I write it in the HTML file, but not if in js file.
