eventDragStop
Triggered when event dragging stops.
function( event, jsEvent, ui, view ) { }
This callback is guaranteed to be triggered after the user drags an event, even if the event doesn’t change date/time. It is triggered before the event’s information has been modified (if moved to a new date/time) and before the eventDrop callback is triggered.
event is an Event Object that hold the event’s information (date, title, etc).
jsEvent holds the native JavaScript event with low-level information such as mouse coordinates.
ui holds the jQuery UI object.
view holds the current View Object.
