I need to implement a marquee style selection in which I would drag a cursor so as to draw a box on an image and return the coordinates while it is dragging (thus live feedback) in a popup/tooltip style fashion and then feed that information back to the rails app.
Is there something out there that already does this or provides the foundations for such a function or do I need to build it from scratch somehow with Scriptaculous or MooTools?
