I seriously doubt this would work. The [] where you have [n=n+1] is
supposed to be a list of html targets whose values will be passed back
to the controller URL('index'). The proper ajax call would be
onclick="ajax('index',[],':eval');return false;". In this case,
"index" is defined in the controller callback routine, "index".
