I'm not sure what your $ajax->div tags are doing because I can't locate that
method in the documentation.
To expand on what John said, you will need to add a value to your $options
array in the AjaxHelper method which requests the function
without any other options it would look something like this
$options = array('complete'=>'if(CHECK IF AJAX RETURNED NULL)
$("style").hide();');
the placement of the $options array parameter depends on the Ajax method, so
check http://book.cakephp.org/view/212/Methods to find out where this value
goes.
Be sure to note the *double quotes* around the $("style") . This is to keep
from breaking the single quotes around the PHP method. You could also do
something like $(\'style\').hide();
I hope this helps,
Dave
