deferred.always()

deferred.always ( alwaysCallbacks, alwaysCallbacks ) Returns: Deferredversion added: 1.6

  • alwaysCallbacks
    Type: Function
    A function, or array of functions, that is called when the Deferred is resolved or rejected.
  • alwaysCallbacks
    Type: Function
    Optional additional functions, or arrays of functions, that are called when the Deferred is resolved or rejected.

Description: Add handlers to be called when the Deferred object is either resolved or rejected.

The argument can be either a single function or an array of functions. When the Deferred is resolved or rejected, the alwaysCallbacks are called. Since deferred.always() returns the Deferred object, other methods of the Deferred object can be chained to this one, including additional .always() methods. When the Deferred is resolved or rejected, callbacks are executed in the order they were added, using the arguments provided to the resolve, reject, resolveWith or rejectWith method calls. For more information, see the documentation for Deferred object.

Examples:

Example: Since the jQuery.get() method returns a jqXHR object, which is derived from a Deferred object, we can attach a callback for both success and error using the deferred.always() method. 

$.get( "test.php" ).always(function() {
  alert( "$.get completed with success or error callback arguments" );
});
