RedirectToAction之后没有视图显示

我有一个登录页面。验证后，我重定向到所需的页面。它重定向但是No

查看appers，而不是显示以前的登录页面视图。

这是我的Javascript代码

    function abc() {
        var email = document.forms["MyForm"]["Email"].value;
        var password = document.forms["MyForm"]["Password"].value;
        if (email.length == 0 || password.length == 0) {
            alert("Email and Password Field Required");
            return false;
        }
        else {

            $.ajax({
                 url: $("#MyForm").attr('action'),
                type: $("#MyForm").attr('method'),
                data: $("#MyForm").serialize(),
                success: function (data) {
                     alert("Invalid Email or Password");
                }
            });
        }
    }
</script>

，这是控制器(HttpPost)

    public ActionResult UserLogin(Models.UserModel selectedDocuments)
    {                                  
        if (ModelState.IsValid)
        {
            long AdminID = IsValid(selectedDocuments.Email, selectedDocuments.Password);
            if (AdminID != 0)
            {
                FormsAuthentication.SetAuthCookie(selectedDocuments.Email, false);
                if (RoleID == 1)
                {
                    Session["SystemAdmin"] = true;
                    Session["AdminID"] = AdminID;
                    return RedirectToAction("ClubInfo", "Admin");
                }
                if (RoleID == 2)
                {
                    Session["ClubAdmin"] = true;
                    Session["AdminID"] = AdminID;
                    return RedirectToAction("ClubInfo", "ClubAdmin");
                }
                if (RoleID == 3)
                {
                    Session["NewsAdmin"] = true;
                    Session["AdminID"] = AdminID;
                    return RedirectToAction("ClubInfo", "NewsAdmin");
                }
            }
            else
            {
                ModelState.AddModelError("", "Login Data Is Incorrect.");
            }
        }
        return Json(new { selectedDocuments = "Whatever you want to send" }, JsonRequestBehavior.AllowGet);
    }

谁来告诉我怎样才能成功。
