issues with ajax calls from js file in asp.net mvc 3

Question

A have an ajax call that executes fine when it is placed in the .cshtml file, after moving the JS to the call stopped working. I did some debuging and it apeared that right action is beeing called and it returns correct data, but I dont enter the ajax success function in the JS.

The same applies to getJSON.

and also no error message is being displayed

here is the code:

$.ajax({
            type: "GET",
            cache: false,
            url: url,
            dataType: "json",
            success: function (data) {
               //...
            },error: function (xhr, ajaxOptions, thrownError) {
                alert(xhr.status);
                    alert(thrownError);
            }
            });
        }

//action:

[HttpGet]
    public JsonResult HasUpdates()
    {
        var hasUpdates = diagnosticManager.AgentHasUpdates();
        return Json(hasUpdates, JsonRequestBehavior.AllowGet);
    }

Am I missing some thing here?

What is the value passed as url and what are the relativepaths to your view and scripts? — Silvermind

yes, it is a relative path, but it is formed correctly + it stops on the breakpoint in the action — CoffeeCode

Can you set a breakpoint in the error handler and see if it gets hit? If not, are there any javascript errors reported in the console? — Michael Hornfeck

You may be getting success just a bit to late because of asynchronization Use a synchronous AJAX call look over here at the answer How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request?
