public class HomeController : Controller
    {
        //
        // GET: /Home/
        UsersRepository repo = new UsersRepository();
        DBHelpers db = new DBHelpers();

        public ActionResult Index()
        {
           var users = new Users();
           return View(users);
        }

        public ContentResult CheckLogin(Users checkuser)
        {
            checkuser = new Users();
            if (db.CheckUserLoginDetails(checkuser))
            {
                return Content("Login Successful:" + checkuser.Email);
            }
            else
            {
                return Content("Login UnSuccessful");
            }
        }


        public ContentResult Register(Users userRegister)
        {
            userRegister = new Users();
            if (db.InsertNewUSerDetails(userRegister))
            {
                return Content("Registration Successful : your ID is : " + userRegister.UserID);
            }
            else
            {
                return Content("There was a problem addding you, please try again");
            }
        }
    }

=================

here is my DBHelpers class

UsersRepository db = new UsersRepository();

        public bool CheckUserLoginDetails(Users user)
        {
            return (from u in db.EUsers where u.Email == user.Email & u.Password == user.Password select u).Any();
        }

        public bool InsertNewUSerDetails(Users newUser)
        {
            newUser = new Users();
            try
            {
                var date = DateTime.Now.Date;
                newUser.JoiningDate = date;
                db.EUsers.Add(newUser);
                db.SaveChanges();
                return true;
            }
            catch (DbEntityValidationException dbEX)
            {
                foreach (var validationerrors in dbEX.EntityValidationErrors)
                {
                    foreach (var valerror in validationerrors.ValidationErrors)
                    {
                        Trace.TraceInformation("Property: {0} Error: {1}", valerror.PropertyName, valerror.ErrorMessage);
                    }
                }
                return false;
            }

        }

}

and here is my Users class

public class Users
    {
        [Key]
        public virtual int UserID { get; set; }

        [Required(ErrorMessage="Required")]
        public virtual string FirstName { get; set; }

        [Required(ErrorMessage = "Required")]
        public virtual string LastName { get; set; }

        [Required(ErrorMessage = "Required")]
        [DataType(DataType.EmailAddress)]
        public virtual string Email { get; set; }

        [Required(ErrorMessage = "Required")]
        [DataType(DataType.Password)]
        public virtual string Password { get; set; }

        [DataType(DataType.Date)]
        public virtual DateTime JoiningDate { get; set; }

    }

You have a trailing , here which might result into a javascript error:

var postdata =
        {
            "FirstName": firstName,
            "LastName": lastName,
            "Email": email,
            "Password": password,  // <-- remove this comma
        };

The javascript error results into the next line not being executed which is e.preventDefault(); and thus the form performs a normal submit and not an AJAX submit. IIRC some browsers actually might tolerate this but others not. Anyway, it's invalid javascript and needs to be fixed.


Make sure you're attaching a different click event to each button.

If you're currently doing:

$('div').click(function(){});

Then insted you'll want to attach a different click event to each button, something like:

$('#registerButtonId').click(function(){});
$('#loginButtonId').click(function(){});
