如何在MVC 4中验证我的表单 [英] How do I validate my form in MVC 4

问题描述

大家好，

我正在使用MVC4。我的表格有问题。我在我的模型中提供了验证检查。但即使在将数据填充到具有验证检查的字段之后，控制器中的相应操作也不会在提交表单时触发。但是当所有字段都被填满时触发。

  public  ContactUsForm（ ）
 {
 statesList =  new  SelectList（ new  List< SelectListItem>（） ，  stateID， 状态）; 
 provinceList =  new  SelectList（ new  List< SelectListItem>（），  provinceID， 省）; 
} 
  public  SelectList statesList { get ;  set ; } 
 
  public  SelectList provinceList { get ;  set ; } 
 
  private   string  _unCandidateFirstName; 
 [必需（ErrorMessage =  请输入您的姓名）] 
 < span class =code-keyword> public   string  unCandidateFirstName { get  { return  _unCandidateFirstName; }  set  {_ unCandidateFirstName =  value ; } 
 
  private   string  _unCandMobilePhone; 
 [必填（ErrorMessage =  请输入您的手机号码）] 
  public   string  unCandMobilePhone { get  { return  _unCandMobilePhone; }  set  {_ unCandMobilePhone =  value ; } 
 
  private   string  _unCandEmail; 
 [必需（ErrorMessage =  请输入您的电子邮件）] 
 < span class =code-keyword> public   string  unCandEmail { get  { return  _unCandEmail; }  set  {_ unCandEmail =  value ; } 
 
  private   string  _unCandLandLine; 
  public   string  unCandLandLine { get  { return  _unCandLandLine; }  set  {_unCandLandLine =  value ; 
 
  private   int  _countryID; 
 [显示（名称=  国家）] 
  public   int  countryID { get  { return  _countryID; }  set  {_countryID =  value ; } 
  public  SelectList国家/地区{获取 { return  LoadCountries（）; 
 
  private   int  _stateID; 
 [显示（名称=  状态）] 
  public   int  stateID { get  { return  _stateID; }  set  {_stateID =  value ; } 
 
  private   int  _provinceID; 
  public   int  provinceID { get  { return  _provinceID; }  set  {_provinceID =  value ; } 
 
  private   string  _unCandEnquiry; 
  public   string  unCandEnquiry { get  { return  _unCandEnquiry; }  set  {_unCandEnquiry =  value ; } 
 
 私人 Guid _userID; 
  public  Guid userID { get  { return  _userID; }  set  {_ userID =  value ; } 
 
  private   int  _referenceId; 
  public   int  referenceId { get  { return  _referenceId; }  set  {_ referenceId =  value ; 
 
  private  SelectList LoadCountries（）
 {
 SM_WEB.Models.SMWebDefaultConnection objSMWebDefaultConnection =  new  SM_WEB.Models.SMWebDefaultConnection（）; 
  var  countryList = objSMWebDefaultConnection.smConn.tblCountries.Where（c = >  c.recordActive ==  true ）。选择（c = >   new  {c.countryID，c.country}）。ToList（）; 
  return   new  SelectList（countryList，  countryID，  country）; 
} 

任何人都可以帮助我..

< blockquote>模型验证可以在Page post back期间完成。您需要使用jquery

进行客户端验证

Hi All,
I am working with MVC4. I have a problem in my form. I have provided validation checks in my model. But even after filling data to the fields having validation checks, the corresponding action in the controller is not triggering when form is submitted. But triggers when all the fields are filled.

public ContactUsForm()
        {
            statesList = new SelectList(new List<SelectListItem>(), "stateID", "state");
            provinceList = new SelectList(new List<SelectListItem>(), "provinceID", "province");
        }
        public SelectList statesList { get; set; }

        public SelectList provinceList { get; set; }

        private string _unCandidateFirstName;
        [Required(ErrorMessage = "Please type your name")]
        public string unCandidateFirstName { get { return _unCandidateFirstName; } set { _unCandidateFirstName = value; } }

        private string _unCandMobilePhone;
        [Required(ErrorMessage = "Please type your mobile number")]
        public string unCandMobilePhone { get { return _unCandMobilePhone; } set { _unCandMobilePhone = value; } }

        private string _unCandEmail;
        [Required(ErrorMessage = "Please type your email")]
        public string unCandEmail { get { return _unCandEmail; } set { _unCandEmail = value; } }

        private string _unCandLandLine;
        public string unCandLandLine { get { return _unCandLandLine; } set { _unCandLandLine = value; } }

        private int _countryID;
        [Display(Name = "Country")]
        public int countryID { get { return _countryID; } set { _countryID = value; } }
        public SelectList countries { get { return LoadCountries(); } }

        private int _stateID;
        [Display(Name = "State")]
        public int stateID { get { return _stateID; } set { _stateID = value; } }

        private int _provinceID;
        public int provinceID { get { return _provinceID; } set { _provinceID = value; } }

        private string _unCandEnquiry;
        public string unCandEnquiry { get { return _unCandEnquiry; } set { _unCandEnquiry = value; } }

        private Guid _userID;
        public Guid userID { get { return _userID; } set { _userID = value; } }

        private int _referenceId;
        public int referenceId { get { return _referenceId; } set { _referenceId = value; } }

        private SelectList LoadCountries()
        {
            SM_WEB.Models.SMWebDefaultConnection objSMWebDefaultConnection = new SM_WEB.Models.SMWebDefaultConnection();
            var countryList = objSMWebDefaultConnection.smConn.tblCountries.Where(c => c.recordActive == true).Select(c => new { c.countryID, c.country }).ToList();
            return new SelectList(countryList, "countryID", "country");
        }

Can any body help me..

解决方案

The Model validation can be done during the Page post back. you need to do the client side validation by using jquery
