Cancel Event Subscription

The method FB.Event.unsubscribe() allows you to un-subscribe a callback from any events previously subscribed to using FB.Event.subscribe().

FB.Event.unsubscribe(event, callback)

Parameters

Name	Type	Description
`event`	`enum{}`	The name of the event type you want to unsubscribe from. Matches the event types shown in `.Event.subscribe()`.
`callback`	`function`	The callback function that you want to unsubscribe from the provided event type. This method call will fail if an existing Event subscription for this callback did not already exist.

Example

var handleResponse = function(response) {
   alert ('You liked the URL: ' + response);
};

FB.Event.unsubscribe('auth.statusChange', handleResponse);
