withinIncludingScrolloffsets :: Position |
This method handles an edge case of Position.within: when element is the child of a scrolling container. (Scriptaculous, for instance, uses it whenever a Draggable’s container is scrollable.) For performance reasons, this method should not be used unless you need this specific edge case.
You must call Position.prepare first, since it calculates offsets that are used by this method. |
