[jQuery] problem with jquery-ajax

[sruthim]

Hi,

I am using the zend framework and using the JQuery - $.getJSON for
this. I am sending a request but I am not getting a response.I tried
an example that somebody has given in this forum - that works..only my
url does not work..I am pasting the code here.

For the action -
  public function freepaidverAction(){
         $data = 'name : hello world';
echo $_GET['jsoncallback'] . '(' . $data . ');';
    }

In the js file -

                                $.getJSON("http://sys8/ShareThePage/freepaidver?
modName=ShareThePage&userName="+userId_STP,
                                            {},
                                            function(data) {
                                                alert('in this');
                                                $(data).each(function(i, item) {
                                                    
alert($(this)[0].photos[i].photo_id);
                                                })
                                            }
                                        );


If I use this url then it works - "http://www.panoramio.com/map/
