asp.net - click mouse position with scroll in javascript

Question

I have code to get x-y coordinates when the browser scrolls:

left1 = window.event.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
top1 = window.event.clientY + document.body.scrollTop + document.documentElement.scrollTop;

This is working in IE7, but not in Mozilla Firefox 3.5.19. How can I get it working in Firefox?

Answer 1

The following JS works in IE 8 and firefox 3.6.17

function getScrollingPosition()
{
var position = [0, 0];
if (typeof window.pageYOffset != 'undefined')
{
position = [
window.pageXOffset,
window.pageYOffset
];
}
else if (typeof document.documentElement.scrollTop
!= 'undefined' && document.documentElement.scrollTop > 0)
{
position = [
document.documentElement.scrollLeft,
document.documentElement.scrollTop
];
}
else if (typeof document.body.scrollTop != 'undefined')
{
position = [
document.body.scrollLeft,
document.body.scrollTop
];
}
return position;
}
