Question

I have an action which is returning this:

return Json(new { success = true, aaa = "bbb"  }, "text/html");

How can I access aaa in my onComplete function?

    onComplete: function (file, response)
    {
        alert(response['aaa']); //undefined
    }

I’m not familiar with onComplete in jQuery. Which Ajax method are you using? You could try console.dir(reponse) in place of your alert to see exactly what is in the response parameter.

The $.ajax() method lets you provide a complete handler (without the “on”), or to actually process the response I’d use a success handler:

$.ajax("yourURLhere", {
       success : function(data, textStatus, jqXHR) {
           alert(data['aaa']);
       },
       complete : function(jqXHR, textStatus) {
           // do something - note that the parameters don't include "data"
           // like the success callback, and "complete" is called after
           // the "success" or "error" callback
       }
});
