Get Current Window W+H dimensions

[Beriah]

Hello,

I want to know how to get the Width+Height of a browser window onload.

im currently trying:
var wiw = window.innerWidth
var dw = document.clientWidth

but unless it is placed within a window that is created wtih specific width/heights stated, i cant get anything but an "undefined" error.

Does anyone have any suggestions?

Regards
Beriah

It depends on your browser and when you poll the window.
Call this function AFTER the window has loaded:

var Ypos, Xpos, theWidth, theHeight;
function WindowSize() {
// Scroll offset:
if (window.pageYOffset)
Ypos=window.pageYOffset;
else if (document.documentElement && document.documentElement.scrollTop)
Ypos=document.documentElement.scrollTop;
else if (document.body)
Ypos=document.body.scrollTop;

if (window.pageXOffset)
Xpos=window.pageXOffset;
else if (document.documentElement && document.documentElement.scrollLeft)
Xpos=document.documentElement.scrollLeft;
else if (document.body)
Xpos=document.body.scrollLeft;
// 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;
}
