Actually, it's a bit more complicated than that... I have a div (we'll call it the "portal") of a fixed size and absolute positioning, with an overflow: scroll set. Inside, I have a container div with relative positioning. This inner container has a series of absolutely-positioned elements which are draggable with a vertical constraint. The height of the container is several times greater than the "portal".
I needed to drag these elements outside the "portal". If I just made the elements draggable, when I got to the boundary of the portal, the elements would disappear on the inside. I solved this by moving the element to the portal's parent container in the onStart handler (while keeping track of the original container so that I could put it back on the onEnd handler. The problem I encountered was when I was dragging elements that required me to scroll down on the inner container. When they came out of the portal, their "top" property was set relative to the inner container. For whatever reason, the event passed to me didn't contain any mouse coordinates, nor was I able to get the scroll distance of the container. I ended up keeping track of the mouse coordinates at all times with a "mousemove" event on the document element. I added an onDrag handler to position the element using the mouse coords I was getting. The problem with doing this was that in dragdrop.js, in the draw method of Draggable, it constantly overwrites the top property with its own calculation which does not work at all in what I needed to do. The only way around this I could find was to disable the 'style.top = p[1] + "px"' (lines 493-494 in v1.8.1 of dragdrop.js). I'm not sure if there is a more elegant way to do this, or if there should be some sort of hook so a developer can use a callback function to calculate the new coordinates, but I did want to share my solution to the problem in case anyone else encountered it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
