Retrieve JSON data from MVC Controllers

I want to retrieve JSOn data from controller and set it for window.location.

in jquery :

 $('.starcontainer').rating(function (vote, event) {
        var el = $(event.target);
        post = el.parent().parent().attr("data-post");
        $(".loading").show();
        // we have vote and event variables now, lets send vote to server.
        var data = JSON.stringify({
            rate: vote, id: post
        });
        $.ajax({
            url: "/blog/rate",
            dataType: "Json",
            data: data,
            contentType: "application/json; charset=utf-8",
            type: "POST",
            success: function (responseData) {
                alert(responseData);
                window.location = responseData.redirect;
            }
        });

    });

and in Controller:

[AllowAnonymous]
    [HttpPost]
    public JsonResult Rate(int id, int rate)
    {
        if (Request.IsAuthenticated)
        {
            try
            {
                var user = _db.UserProfiles.SingleOrDefault(u => u.UserName == User.Identity.Name);
                PostScore score = new PostScore();
                score.BlogPostId = id;
                score.Score = rate;
                score.UserId = user.UserId;
                _db.PostScores.Add(score);
                _db.SaveChanges();
            }
            catch (System.Exception ex)
            {
                // get last error
                if (ex.InnerException != null)
                    while (ex.InnerException != null)
                        ex = ex.InnerException;

            }
        }
        else
            return Json(new { redirect = Url.Action("Login", "Account") }, JsonRequestBehavior.AllowGet);

        return Json(new { redirect = Url.Action("Index") }, JsonRequestBehavior.AllowGet);
    }

When i run it, retrieve json data {"redirect":"/Account/Login"} for jquery. and redirect to http://localhost:2478/undefined (return undefined for redirect).

if i return Json(Url.Action("Login", "Account") , JsonRequestBehavior.AllowGet); it redirect to http://localhost:2478/%22/Account/Login%22

How to retrieve a url data from controller?

According to firebug console you are getting response as string so parse it to json as it is returned as string:

"{"redirect":"/Account/Login"}" 

success: function (response) {
     var data = JSON.parse(response);    
     window.location.href = data.redirect;    
}

The below code is working fine for me

return Json(new { Redirect = "/Account/Login" },JsonRequestBehavior.AllowGet);

and ajax success

success: function (response) {    
     window.location.href = response.Redirect ;    
}
