- .deferred.progress( Function progressCallbacks )
progressCallbacks A function, or array of functions, that is called when the Deferred generates progress notifications.
The argument can be either a single function or an array of
functions. When the Deferred generates progress notifications by
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. For more information, see the documentation for Deferred object.
