# deferred.always()

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.

Note: The deferred.always() method receives the arguments that were used to .resolve() or .reject() the Deferred object, which are often very different. For this reason, it's best to use it only for actions that do not require inspecting the arguments. In all other cases, use explicit .done() or .fail() handlers since the arguments will have well-known orders.

alwaysCallbacks

A function, or array of functions, that is called when the Deferred is resolved or rejected.

alwaysCallbacks

Optional additional functions, or arrays of functions, that are called when the Deferred is resolved or rejected.

Examples:

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" );
});
