JSON Response not parsing, using Wordpress and AJAX

Question

I have a front end editor set up using AJAX to edit posts in Wordpress. Everything was going good, my form submits to a php file which successully updates the database and then uses the following function to create a response:

  function generate_response($action, $message = '', $details = '' ){
    $response = array(
        "action"  => $action,
        "message" => $message,
        "details" => $details
        );

    echo json_encode($response, JSON_FORCE_OBJECT);
}

However, the response does not appear to be encoded properly, When I log my jsonResponse return in JS I'm getting this:

Object {action: "updated", message: "Succes (no changes detected).", details: ""}

Which I'm pretty sure is malforemd JSON because action, message, and details are not double-quoted, right?

I try to parse the response and all I get is null:

  response = jQuery.parseJSON(jsonResponse);
  console.log(response); //returns null

What am I doing wrong here? Am I correct and the response is not fomratted properly and if so, how would I fix it?

When you log the result from ajax, you get:

Object {action: "updated", message: "Succes (no changes detected).", details: ""}

That's already an object, not a JSON string, which means you probably set dataType: 'JSON' in your ajax call, and JSON is parsed automagically by jQuery, parsing it again just causes errors.

All you need to do is use response, no parsing needed :

var action = response.action;

I ran into some different issues which I'll have to figure out before I can know if you're answer was right, although I'm pretty sure it is.

@adeneo So when I am running a query to load top 5 posts and then whaterver results I am getting they would be encoded to json.The output I am getting would be a object and not a JSON string right?

Yesterday spent few hours doing stringify- just to convert it to json assuming myoutput was a json string.

If whatever is returned from the server is properly encoded, like with json_encode, and dataType is set to JSON in jQuery's ajax function, the result will be a javascript object ready for use, as jQuery does the JSON.parse part internally for you.
