Howto get the viewport height and width WITHOUT scrollbar?

[BlackDex]

Hello there,

I Have an small problem.
I Need to get the viewport width and height.

I Tested the following:
Real size without scrollbars:
- Height: 389px
- Width: 614px

----

window.innerHeight & window.innerWidth: 
 - Opera: H:405 - W:630 
 - FF:  H:405 - W:630 
 - IE:  H: x - W: x 
document.body.clientHeight & document.body.clientWidth: 
 - Opera: H:389 - W:614 
 - FF:  H:431 - W:598 
 - IE:  H:389 - W:614 
document.documentElement.clientHeight & document.documentElement.clientWidth: 
 - Opera: H:571 - W:614 
 - FF:  H:389 - W:614 
 - IE:  H: 0 - W: 0 

How can i get the inner height and width without scrollbars from all browsers, without doing an browser detect.

a) Use a full (strict) doctype
b) Try again :)

a) this whas already the case.

But it could be i forgot to do this in my testing script :S.

Can't remember, so i have to do it again.

Thx for the reminder.

I ReTryed it with an valide doctype.

Same results, except that IE has an value in document .documentElement.client*.

I would suggest you to use some js cross-browser library.
