Question

enter code here我使用客户端表单验证，但它无效。

我的模特：

[Key]
public int Id { get; set; }

[Required(ErrorMessage = "Error")]
[RegularExpression(@"^[0-9\.]*$",ErrorMessage="Error")]
public string Scode { get; set; }

我的观点：

@Html.ValidationSummary(true)
@using(Html.BeginForm("CreateSharshomari", "VahedInfo", FormMethod.Post))
{
    @Html.TextBox("Scode")
    @Html.ValidationMessage("Scode")

    <input id="BtnErsal" type="submit" value="ارسال" />
}

可能出现什么问题？

它是我的控制器。我想也许我有一个问题。请看一下并说出你的意见。

    public PartialViewResult CreateSharshomari()
    {
        IEnumerable<Lcity> Lcitys = Dbcon.Lcitys;
        IEnumerable<RFaaliat> RFaaliats = Dbcon.RFaaliats;

        var query = Lcitys.Select(x => new SelectListItem
            {
                Value = x.Citycode.ToString(),
                Text = x.CityName,
                Selected = x.Citycode == 1
            });
        var query1 = RFaaliats.Select(x => new SelectListItem
            {
                Value = x.IDReshteh.ToString(),
                Text = x.ReshteName,
                Selected = x.IDReshteh == 1
            });

        var model = new CityFaaliatViewModel
        {
            Lcitylist = query.AsEnumerable(),
            RFaaliatList = query1.AsEnumerable()
        };
        return PartialView(model);
    }
    [HttpPost]
    public ActionResult CreateSharshomari(TaavoniInfo Info,CityFaaliatViewModel selcode)
    {
        try
        {
            TaavoniInfo idcity = Info;
            idcity.idCitycode = Convert.ToInt32(selcode.SelectedCitycode);
            idcity.idIDReshteh = Convert.ToInt32(selcode.SelectedIDReshteh);
           Dbcon.TaavoniInfos.Add(idcity);
            Dbcon.SaveChanges();
            ViewBag.SuccessMsg = "success";
            return View();
        }
        catch
        {
            ViewBag.SuccessMsg = "error";
            return View();
        }
   }

请帮帮我。

您是否导入了如下所需的jQuery文件？如果没有，那么我会邀请你这样做。

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>

鉴于您的模型：

public class MyViewModel
{
  [Key]
  public int Id { get; set; }

  [Required(ErrorMessage = "Error")]
  [RegularExpression(@"^[0-9\.]*$",ErrorMessage="Error")]
  public string Scode { get; set; }
}

<强>控制器：

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

查看：

@model SomeAppName.Models.MyViewModel <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using(Html.BeginForm("CreateSharshomari", "VahedInfo", FormMethod.Post)) { @Html.ValidationSummary(true) @Html.TextBox("Scode") @Html.ValidationMessage("Scode") <input id="BtnErsal" type="submit" value="ارسال" /> }

请注意，您必须在Web.config文件中包含以下密钥，以便在客户端上运行验证：

<add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" />

或在App_Start中

protected void Application_Start() { //Enable or Disable Client Side Validation at Application Level HtmlHelper.ClientValidationEnabled = true; HtmlHelper.UnobtrusiveJavaScriptEnabled = true; }

MVC中的验证无效
