[jQuery] How to get the entire width of a page

[Geoffrey Knutzen]

Seems simple. How do I calculate the entire width of a page, even when there
are scroll bars?

 

I am using the dimensions plug in

 

($("html").innerWidth();

$("html").width());

($("body").innerWidth();

$("body").width());

($(document).innerWidth();

$(document).width());

 

All seem to return the same number, at least in FF. 

 

But if there are horizontal scroll bars, they only return the width of the
visible area, not the entire width of the page.

How do I get the entire width of a page?

 

Thanks
