[Seaside] Image Zoomer: How to capture mouseOver X & Y

[Robert Sirois]

Ugh, I give up. For some reason this is easy to do in Prototype, but I can't figure it out at all in jQuery...

What I'd like to do is get the position of the mouse (http://docs.jquery.com/Types/Event#event.pageX.2FY) and send the value to an ajax callback like below:

...
        onClick: (html jQuery ajax
            callback: [:v | self session mousePosTop: v ] value: 'y val';
            callback: [:v | self session mousePosLeft: v ] value: 'x val'
        );
...

Near as I can tell, in PT you have access to the actual event parameter via the PTEvent class, which doesn't seem to exist in jQ, but the part I'm confused about is that both implement #call:with: on JSObject, but I guess the JavaScript libraries respond differently.

jQuery uses pageX/pageY quite extensively (especially UI), so I would think they would have a function returning those values?

Thanks,
RS
