*update 10:55am 21-Mar-08*
I have decided to use the following code instead as it looks a bit cleaner, and more up-to-date.
Tested on Firefox 2 and IE 6.
document.onmousemove = mouseMove;
function mouseMove(ev){
ev = ev || window.event;
var mousePos = mouseCoords(ev);
}
function mouseCoords(ev){
if(ev.pageX || ev.pageY){
return {x:ev.pageX, y:ev.pageY};
}
return {
x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
y:ev.clientY + document.body.scrollTop - document.body.clientTop
};
}
