Question

I’m currently working in asp.net mvc 4. I’ve written a function which return a JSON-object.

This is the function (in my controller)

[HttpPost]
        public ActionResult Login(string email, string password)
        {
            ViewData["Message"] = "None";
            JSONLoginModel model = new JSONLoginModel();

            Account account = _accountRepository.CheckLogin2(email, password);

            if (account != null)
            {
                model.Email = email;
                model.Password = password;
                model.ChangePassword = account.ChangePasswordOnLogin;
            }

            return Json(model);
        }

And this is the JSONLoginModel

[Serializable]
    public class JSONLoginModel
    {
        public string Email { get; set; }
        public string Password { get; set; }
        public bool ChangePassword { get; set; }
    }

I’ve also written the following JQuery code to catch and use it

$.post("Home/Login", { email: email, password: password }, function (data) {
                alert(data);
                $.each(data, function (index, IntraNoviUser) {
                    if (IntraNoviUser !== undefined && IntraNoviUser !== null) {
                        alert('test1');
                        alert(IntraNoviUser.password, IntraNoviUser.email);
                        alert('test2');
                    }
                });
            });

Everything goes fine until I try to use the result that was returned.

What I get back from my controller is an object which can have 3 options:

1. null
2. email + password filled in and changePassword is false
3. same as 2, but changePassword = true

The problem is that my returned JSON object is never recognized.
Any hint on this?

I Think asp.net resturns json data as d. So you better alert(data.d) and check it.

$.post("Home/Login", { email: email, password: password }, function (data) {
                if(data!=null || data != undefined){
                   if(data.password==true){
                  //do something
                   }
                 else if(data.password==false){//do something

                   }
                }

            });
