Using jquery scrollTop to position absolute Div

Question

Hello,

I am trying to position an Absolute DIV using Jquery, depending on where the user is clicking on the page.

At the moment this works just great

$('#window').css('left', jsEvent.pageX);
$('#window').css('top', jsEvent.pageY);

This positions the element exactly where my mouse has clicked the screen...

Until you scroll down that is. That is why I am trying to achieve something that will take the amount of pixels from the top of the page into account. I thought something like this...

$('#window').css('top', jsEvent.pageY + scrollTop());

would do the trick, unfortunately it doesn't work.

Any hints?

Thanks,

Tim

This definitely works in Firefox. As such, it should work in Chrome, Safari and Opera. IE however, I'm not entirely sure. Give it a shot.

$('#window').css({
    left: e.clientX
    , top: e.clientY + document.documentElement.scrollTop
});

EDIT: This new version should work in most, if not all browsers.

var rxp = /webkit/gi;

$('#window').css({
   left: e.clientX
   , top: e.clientY + rxp.test(window.navigator.userAgent) ? document.body.scrollTop : document.documentElement.scrollTop
});
