A while ago I tinkered with an Ajax webapp and I used this line :

  if(@$_GET['ajax']>'') $EnableRedirect = 0;

The JavaScript sends the PmForm with an additional parameter "&ajax=1". This 
blocks the redirects and sends a HTML page and the JavaScript program can 
parse it and decide what to do.

Alternatively, you can write/clone your own MyHandlePmForm() without the 
redirect, and use $HandleActions['pmform'] = 'MyHandlePmForm';

It might be more something like this :
  SDV($PmFormRedirectFunction,'Redirect');
  $PmFormRedirectFunction($pagename, '{$PageUrl}?pmform=success');
