JQuery JSON set items

Question

Hi all,
I used to use the less functional ajax call using:
var ajaxRequest = new htmldb_Get(null, &APP_ID., 'APPLICATION_PROCESS=APP_MY_OD', 1);
//add all my variables I wish to access in my OD
ajaxRequest.add('P1_X', $v('P1_X'));
data = ajaxRequest.get();
//my OD then sets a string formatted JSON for return using apex_util.json_from_items('P1_X') and adds to session
//with the return string in JSON format set the items value using json_SetItems
json_SetItems(data);
So I understand that the function json_SetItems parse the string when in JSON format.
My question, is there a similar json_SetItems function that will set items when a jQuery object JSON is returned? The one that's returned from the following:
$.ajax({
  type: 'POST',
  data:
// etc...
success: function (data) {
    //data is now a jQuery object, are there any built in functions for this?
I understand I could always make the dataType 'text' which would return a string and call the json_SetItems but was hoping to use dataType 'JSON'
Thanks

"data" is not a jQuery object. It is the returned data in a type specified by the dataType parameter. jQuery docs:
dataType (default: Intelligent Guess (xml, json, script, or html))
Type: String
The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).
The success parameter is defined as this:
success
Type: Function( PlainObject data, String textStatus, jqXHR jqXHR )
A function to be called if the request succeeds. The function gets passed three arguments: The data returned from the server, formatted according to the dataType parameter; a string describing the status; and the jqXHR (in jQuery 1.4.x, XMLHttpRequest) object.
So I'm not sure what exactly it is you're after. If you want plain text back then request it as such. If you'd rather have JSON then go with that.
