Re: Access a returned AJAX value

Hi tobi_one,

I had the exact same problem and never got an answer:
http://groups.google.com/group/cake-php/browse_thread/thread/6a8bca31cbc37600/68463ae52185dd1a
http://groups.google.com/group/cake-php/browse_thread/thread/e96a87bb82267767

In the end, I abandoned the CakePHP ajax helper and did it in straight
javascript. It was much easier than I thought, and I learnt something
about the inner workings of ajax. I think you'll find it's quite
easier this way. IMO it's one of thoswe situations where the
simplified "helper" gets in the way, and the best is to get to the
nuts and bolts. I used the example from the book http://ajaxphp.packtpub.com/
and the free sample chapter that will give you a template to work from
for the ajax call http://ajaxphp.packtpub.com/1825_01_Final.pdf

Good luck
