I am try to detect the mouse pointer by
var event = window.event;
var x = event.pageX;
var y = event.pageY;
This is working fine in IE, but in
Netscape/Firefox where event return undefined.
Can someone tel me how to detect mouse pointer
in Netscape/Firefox?
Thank Q very much in advance!

Utilizo da seguinte maneira
var ns4 = (document.layer s) ? true : false ;
var ie4 = (document.all) ? true : false;
function ColumnOnMouseMo veEvent (e){
var mouseX = 0;
mouseX=ie4? event.clientX : e.clientX;
var mouseY = 0;
mouseY=ie4? event.clientY : e.clientY;
}

And what about NS6/7/8, Mozilla, Firefox, Opera 5/6/7/8, or any other
browser that doesn't support document.all or document.layers or that
does support them but not e.clientX (in the case of document.all)?
Don't assume that one test implies other features. Test for the features
you want to use directly.
mouseX = (e.clientX)? e.clientX : event.clientX;
mouseY = (e.clientY)? e.clientY : event.clientY;

Read about getting mouse co-ordinates (and events in general) here:
<URL:http://www.quirksmode. org/js/events_properti es.html>
Based on the above reference, to get the cursor's co-ordinates from an
event:
function someFn(e)
{
var e = e : window.event;
var posx = 0;
var posy = 0;
if (e.pageX || e.pageY) {
posx = e.pageX;
posy = e.pageY;
} else if (e.clientX || e.clientY) {
posx = e.clientX + document.body.s crollLeft;
posy = e.clientY + document.body.s crollTop;
}
// posx and posy contain the mouse position relative to the document
// Do something with this information
}
And in the html:
<... onclick="someFn (event);" ...>

Detects true for Netscape 4 or OmniWeb (and isn't used here)
var ie4 = (document.all) ? true : false;
Detects true for IE or Opera or probably a few more.
function ColumnOnMouseMo veEvent (e){
A less fragile solution, that doesn't involve detecting the browser,
is to start the function with:
e = e || window.event;
If the event is passed as a parameter to the function (as Netscape and
W3C DOM Events compatible browsers do) this statement does nothing.
If not, it assumes that the event is available as a global variable
(as in IE).
To my knowledge, there is no browser supporting Javascript and events
that does neither.
var mouseX = e.clientX;
var mouseY = e.clientY;

Hi everyone,
I'm writing a function (in javascript) that needs to do one thing if
the page has not loaded, and another (different) thing if the page has
already loaded.
I'm looking for a way to tell if the window.onload event has already
fired. I cannot edit the onload event handler itself, and my function
can only exist in an external js file, sourced from the document's
head section. Any ideas?

If I use this code to maximise a browser window:
window.moveTo(0,0);

it works but on Windows the user can have a taskbar visible and the
browser window goes behind it.
Is there a way to know where the taskbar is?

Once the new document has been created it then prints the document and
closes it with the following code:

This works correctly (or at least the way I expect it to work under MS

Hi,
Is there a standard for the global 'window' object in browsers? For
example, it supports methods such as setInterval and clearInterval, and
several others.
I know that w3c standardized several parts of the DOM, but this does
not include the window object.
Thank you

Hi,
I am trying to pop-up a window when the user clicks on an image. The
problem is that when the user clicks on the image and the window pops
up OK, but the window underneath also proceeds to the image. The
desired behavior is that when the pop-up is invoked, I want the
underlying window to stay put.
I don't have this problem when I run the code on my local computer but
I do have it when I run the code on geocities.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
