Hi,
> What am I doing wrong?
You're just looking in the wrong place. The second parameter to the
onSuccess callback is the value of the X-JSON *header*, if any. It's a
means of sending back extra data alongside the main response. You're
sending JSON back in the body, not a header. To access that, just look
at the `responseJSON` property of the response object (the first
parameter to the onSuccess). E.g.:
new Ajax.Request(url, {
onSuccess: function(response) {
// The decoded JSON data is available from
// the response.responseJSON property.
}
});
([OT] You've called your first parameter "transport", probably because
you've seen that in examples from a long time back. It's not the
transport, it's an Ajax.Response object. And yes, the docs are wrong;
I've filed a ticket in Lighthouse about that.)
HTH,
