MVC所需的字段不工作
MVC所需的字段不工作
提问于 2013-09-09 20:53:42
有人能发现我做错了什么吗？我尝试了一下我的HTMlValidation摘要和其他一些东西。我觉得这可能与我从我的控制器类返回的视图有关。
-- Model
public class Login
{
[Required(ErrorMessage = "First Name is required")]
[Display(Name = "First Namex")]
public string FirstName { get; set; }
[Required(ErrorMessage = "Password is required")]
[DataType(DataType.Password)]
[Display(Name = "Passwordx")]
public string Password { get; set; }
}
-- Controller
[HttpPost]
public ActionResult Login(string FirstName, string Password)
{
if (ModelState.IsValid)
{
bool validLogin = new UserBAL().ValidateUser(FirstName, Password);
{
if (validLogin == true)
{
return RedirectToAction("Index", "Invoice");
}
else
{
return RedirectToAction("Index");
// ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
}
}
return View();
}
--View
@using (Html.BeginForm("Login", "Home"))
{ @Html.ValidationSummary(true)
<div>
<fieldset>
<legend>Login</legend>
<div class ="fields">
@Html.LabelFor(u => u.FirstName)
</div>
@Html.TextBoxFor(u => u.FirstName)
@Html.ValidationMessageFor(u => u.FirstName) <br />
<div class ="fields">
@Html.LabelFor(u => u.Password)
</div>
@Html.PasswordFor(u => u.Password) <br />
<input type="submit" value="Log In" />
</fieldset>
</div> }
[HttpPost]
public ActionResult Login(EIAS.Models.Login login)
{
if (ModelState.IsValid)
{
bool validLogin = new UserBAL().ValidateUser(login);
{
if (validLogin == true)
{
return RedirectToAction("Index", "Invoice");
}
else
{
return RedirectToAction ("Index");
// ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
}
}
return View();

if (ModelState.IsValid)中的MVC验证模型，并且在操作中没有接收到该模型：
public ActionResult Login(string FirstName, string Password)将操作参数更改为：
public ActionResult Login(Login model)此外，要在客户端进行验证，请检查：
- 如果包含jquery，则验证插件(js)
- 检查您的web.config，键
ClientValidationEnabled和UnobtrusiveJavaScriptEnabledir为true。

您必须将模型作为登录操作的参数
public ActionResult Login()
{
// This will return the view with the form that you have above
return View();
}
[HttpPost]
public ActionResult Login(Login login)
{
// this is what your form will post too
if (ModelState.IsValid)
{
bool validLogin = new UserBAL().ValidateUser(login.FirstName, login.Password);
{
if (validLogin == true)
{
return RedirectToAction("Index", "Invoice");
}
else
{
return RedirectToAction("Index");
// ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
}
}
return View();
}在视图中才有
@using (Html.BeginForm())下面是关于MVC Razor表单的链接：http://blog.michaelckennedy.net/2012/01/20/building-asp-net-mvc-forms-with-razor/
试试看。
