javascript - 首次写入错误密码时，甜蜜警报未显示错误/成功警报

Question

我正在尝试在登录面板中显示错误/成功警报。但是第一次输入错误/正确密码时，甜蜜警报不会显示错误/成功警报。我必须再写一次错误的密码来显示甜蜜的警报。我不明白为什么会这样。我试图用断点检查代码。第一次去Login.cshtml，虽然ViewBag.status是假的，但它不会去if (ViewBag.status==false)。有人能帮我吗？

控制器;

    [HttpGet]
    public ActionResult Login()
    {
        return View();
    }
    [HttpPost]
    public ActionResult Login(TBLUSER t)
    {
        var values = db.TBLUSER.FirstOrDefault(x => x.MAIL == t.MAIL && x.PASS == t.PASS);
        bool status;
        if (values != null)
        {
            FormsAuthentication.SetAuthCookie(values.MAIL, true);
            status= true;
            ViewBag.status = status;
            Thread.Sleep(2500);
            return RedirectToAction("Index", "Panel");
        }
        else
        {
            status = false;
            ViewBag.status = status;
            Thread.Sleep(2500);
            return View();
        }
    }
