Abstract: Technologies are described herein for implementing a cross-browser drag-and-drop library. The drag-and-drop library creates a draggable object corresponding to a drag source element and a droppable object corresponding to a drop target element defined in a webpage. The draggable object and droppable object are each assigned a link key value. A user-defined data structure populated with data regarding the drag source element may also be assigned to the draggable object. A browser event indicating a drag-and-drop operation between the drag source and the drop target is intercepted, and the drag-and-drop library determines whether the link key value assigned to the corresponding draggable and droppable objects are the same. If the link key values are the same, the drag-and-drop library generates an event associated with the droppable object to facilitate an application-related operation associated with the drag-and-drop operation using the data in the user-defined data structure.
