There are some global callbacks [1]. You might be able to use
Global Ajax call listeners
IAjaxCallListener's can be used to listen for the lifecycle of an Ajax call
for a specific component.
If the user application needs to listen for all Ajax calls then it may
subscribe to the following topics:
- /ajax/call/before
- /ajax/call/precondition
- /ajax/call/beforeSend
- /ajax/call/after
- /ajax/call/success
- /ajax/call/failure
- /ajax/call/complete
Those replaces the old
Wicket.Ajax.(registerPreCallHandler|registerPostCallHandler|registerFailureHandler)
methods and uses publish/subscribe mechanism.
Example (JavaScript):
Wicket.Event.subscribe('/ajax/call/failure', function(jqEvent, attributes,
jqXHR, errorThrown, textStatus) {
// do something when an Ajax call fails
});
All global listeners receive the same arguments as the respective
IAjaxCallListener handler plus
jQuery.Event<http://api.jquery.com/category/events/event-object/> that
is passed by the PubSub system. This event is not the event that caused the
Ajax call. The one that caused the Ajax call is 'attrs.event'.
