jQuery JSONP Example

Click the button to see some feedback returned from another server using JSONP:


Another example using a named callback function:

The php code is: 
<?php
header("content-type: application/json"); 

// Create a generic object.
// Assign it the properties of id (optional - id of target HTML element, from URL) 
// and 'message' - the feedback message we want the user to see. 
if (isset($_GET['id'])) $rtnjsonobj->id = $_GET['id']; 
$rtnjsonobj->message = "You got an AJAX response via JSONP from another site!";


// Wrap and write a JSON-formatted object with a function call, using the supplied value of parm 'callback' in the URL: 
echo $_GET['callback']. '('. json_encode($rtnjsonobj) . ')';    

?>
