Hi sethammons, In fact you can pick every element position with prototype, not just for a draggable. The method to use is Element.cumulativeOffset at http://api.prototypejs.org/dom/element.html#cumulativeoffset-class_method If there is a scroll bar that modify position of the element, prefer the Element.cumulativeScrollOfset at http://api.prototypejs.org/dom/element.html#cumulativescrolloffset-class_method
of course both method could be call with element#cumulative... -- david On 25 nov, 01:43, sethammons <seth.amm...@gmail.com> wrote: > Hi all! > I'm a php person, and relatively new to javascript -- so I appreciate > any help I can get!
