Use the appropriate headers on the server.
If you send (PHP) ...
header("{$_SERVER['SERVER_PROTOCOL']} 200 OK", True, 200);
header('Content-type: X-JSON');
echo json_encode($m_Response);
or
header("{$_SERVER['SERVER_PROTOCOL']} 200 OK", True, 200);
header('Content-type: application/javascript');
echo "{$_POST['JSONP']}(" . json_encode($m_Response) . '); //';
for JSON/JSONP, then prototype will handle it correctly.
But if you are NOT sending JSON encoded data, but straight HTML, then
you use the text/html content type.
So. When this gets to prototype, the second param will be populated
for the JSON data (up to you to process the object).
The JS will be executed for JSONP (you don't need to do anything else).
The HTML will be sent to the appropriate container (if you are using
an updater request).
No need to "determine" anything. Just use the right headers.
Well, you could test to see if the second param to the onSuccess is
present. If so, then it is JSON, if not then it is not.
