Json request with jQuery don't be evil'

Jesus how complex can it be!  For our hyves/facebook gadget we needed to fetch some json from our website. After getting the < don't be evil' > message for a while we figured it out.

If this is your call:
function getJson() {
    $.getJSON(http://www.yourdomain.com/hyvesapp/json?callback=?,
            function(data){
               alert("got here"+data.name);
    });
}

In your code you have to do some things to get this working, jQuery adds a function name to the ? at the end (see the manual) so you need to readout the callback GET param in your script to get it to work.

This is the function is used:
function hyvesappCreatejson(){
    header("Content-Type: application/json;");
    $obj = new stdClass;
    $obj->name = "yourname";
    $obj->url = "www.gijs.com";

    echo $_GET['callback'].'('.json_encode($obj).')';exit;
}

Hope this helps.
