Capturing x and y coordinates of page in firefox

[psgfcyt]

I am using a jquery plugin to display page. I am able to capture coordinates of entire page in Chrome and IE but when i try to do the same with Firefox, it captures the screen coordinates and not the page. Can somebody help.Code : \[code\]$('.page').bind('click', function(event) { var x; var y; if (!(event.offsetX || event.offsetY)) { x = event.clientX; y = event.clientY; } else { x = event.offsetX; y = event.offsetY; } alert("x :" +x +", y: " +y);}); \[/code\]
