ASP.NET MVC 2+jquery lightbox+登录

下面是accountcontroller.cs中的登录操作

public ActionResult LogOn(LogOnModel model, bool rememberMe, string returnUrl)
        {
            if (ModelState.IsValid)
            {
                if (MembershipService.ValidateUser(model.UserName, model.Password))
                {
                    FormsService.SignIn(model.UserName, rememberMe);
                    if (!String.IsNullOrEmpty(returnUrl))
                    {
                        return Redirect(returnUrl);
                    }
                    else
                    {
                        return RedirectToAction("Index", "Home");
                    }
                }
                else
                {
                    ModelState.AddModelError("", "The user name or password provided is incorrect.");
                }
            }

            // If we got this far, something failed, redisplay form
            return View(model);
        }

最终返回视图(模型)可以更改为返回不同的内容,可能类似以下内容:

return PartialView("LogOnFailed",model);

验证错误保存在modelstate中,modelstate是一个专门的模型验证错误字典,您可以对其进行迭代:

foreach(var error in ModelState)
{
    //do stuff
}
