Question

I was told that $.getJSON is the best way to send data to and from external servers. I probably wasted 7 hours of my time trying to use JQUERY’s Ajax to do so just to find out that no browsers allow that type of method. I would like to send the data using the Jquery getJSON and I am using cakephp as my receiving end (i.e. My external server) Here is what i have so far.

$.getJSON("http://play.mysite.com/usersessions/store/",{ data: "Hi!"});

I don’t want a callback because I dont need it. I just need to send some data to the external server. This is MVC site so usersessions is my controller, store is my action.

Below is my cakephp code. If you don’t know it then that is fine. I just really need to know if I am sending the getJSON data correctly

<?php class UsersessionsController extends AppController {

var $name = 'Usersessions';
var $helpers = array('Html', 'Form','Ajax');
var $components = array('RequestHandler');


function store()
{
   Configure::write('debug', 0);
   $this->autoRender = false;

   if($this->RequestHandler->isAjax()) {
       if ($this->params['url']['data'])
       {
           $this->data['Usersession']['data'] = $this->params['url']['data'];
            $this->Usersession->Save($this->data);
            echo 'Success';
        }   
   }    
}

}
?>

Thanks you!

Answer 1

getJSON() is for reading JSON data from the server. If you just want to send some parameters from the browser to the server, just use get() and don’t use the optional callback.

From the docs:

Request the test.php page and send some additional data along (while still ignoring the return results).

 $.get("test.php", { name: "John", time: "2pm" } );
