Asp.net mvc中的属性验证
我正在尝试验证用户在表单中输入的字段。我试过了,但它根本没有验证字段。即使我没有输入任何记录,它也不会给出错误消息。我还需要添加脚本或库之类的内容吗? 要添加哪个库 视图模型(类): 以下是观点:Asp.net mvc中的属性验证,asp.net,asp.net-mvc,asp.net-mvc-4,Asp.net,Asp.net Mvc,Asp.net Mvc 4,我正在尝试验证用户在表单中输入的字段。我试过了,但它根本没有验证字段。即使我没有输入任何记录,它也不会给出错误消息。我还需要添加脚本或库之类的内容吗? 要添加哪个库 视图模型(类): 以下是观点: <form action="@Url.Action("Index","SignUp")" class="form-horizontal" method="post"> Full Name @Html.TextBoxFor(x => x.Full_Name, new { @c

HttpPost操作中的当前代码总是使用
RedirectToAction
方法返回RedirectResult。如果希望在提交表单时查看模型验证框架生成的验证错误,则需要返回到同一视图
您还可以使用ModelState.IsValid
属性检查提交的表单数据是否通过了验证。如果有,您可以继续执行代码,如保存到db和重定向
[HttpPost]
public ActionResult Index(RegisterationLoginViewModel svm)
{
if(ModelState.IsValid)
{
//save
var result = db.Register(svm);
return RedirectToAction("ThankYou_View");
}
//Model validation failed. Let's return to same view.
// to do : Make sure to reload any stuff you need in view (Ex: ViewBag etc)
return View(svm);
}
您的httppost操作方法是什么样子的?[httppost]公共操作结果索引(RegisterationLoginViewModel svm){if(svm==null){RedirectToAction(“null\u SignUp\u View”);}字符串RegisterStudent\u Response=db.Register(svm);if(RegisterStudent_Response==“1”){RedirectToAction(“Thankyu_View”)}返回RedirectToAction(“Thankyu_View”)}
[HttpPost]
public ActionResult Index(RegisterationLoginViewModel svm)
{
if(ModelState.IsValid)
{
//save
var result = db.Register(svm);
return RedirectToAction("ThankYou_View");
}
//Model validation failed. Let's return to same view.
// to do : Make sure to reload any stuff you need in view (Ex: ViewBag etc)
return View(svm);
}
