deferred.progress( progressCallbacks [, progressCallbacks ] )Returns: Deferred
Description: Add handlers to be called when the Deferred object generates progress notifications.
-
version added: 1.7deferred.progress( progressCallbacks [, progressCallbacks ] )
-
progressCallbacksA function, or array of functions, to be called when the Deferred generates progress notifications.
-
progressCallbacksOptional additional function, or array of functions, to be called when the Deferred generates progress notifications.
-
The deferred.progress() method accepts one or more arguments, all of which can be either a single function or an array of functions. When the Deferred generates progress notifications by calling notify or notifyWith, the progressCallbacks are called. Since deferred.progress() returns the Deferred object, other methods of the Deferred object can be chained to this one. When the Deferred is resolved or rejected, progress callbacks will no longer be called, with the exception that any progressCallbacks added after the Deferred enters the resolved or rejected state are executed immediately when they are added, using the arguments that were passed to the .notify() or notifyWith() call.
