[jQuery] Beginner needs help with jquery and ajax

[Julien Martin]

Hello,

I basically want to catch any ajax request sent by my app and display an
alert.

I have tried this to no avail:

*jQuery("*").ajaxSend(function(event,request, settings){
   alert('called');
});*

whenever an ajax request is made the alert does not show...

note that the ajax request is made by the richfaces framework using an
a4j:commandButton.

Can anyone please advise,

Thanks in advance,

Julien.
