MV3 输入验证 - IE8 & IE9 的行为有所不同

发布于 2024-11-16 21:38:07 字数 1354 浏览 1 评论 0原文

我正在使用 DataAnnotations 来验证 MVC3 应用程序上的输入字段。我正在使用正则表达式验证。我在 IE8 和 IE8 的 UI 上收到验证消息IE9。但即使在客户端验证失败后，当我点击“保存”按钮时，我还是注意到了差异。 IE9 让我留在客户端。然而，在 IE8 上，控件转到控制器操作，我必须有一个控制器端 TryValidateModel，以便验证错误。

有谁知道为什么 IE8 会进行服务器往返？

编辑：添加代码。这进入cshtml。

    @using (Html.BeginForm("Person", "Account", FormMethod.Post))
    {
       <span class="resultError" id="resultError">
       @Html.ValidationMessageFor(model => model.Name, "Name should not contain special characters")  
       </span>
       <table>
         <tr>
          <td class="editor-label">Name:
          </td>
          <td class="editor-field">@Html.EditorFor(model => model.Name)
          </td>
        </tr>
       </table>
       <input type="submit" name="btnKey" value="Save" />
    }

这是使用 DataAnnotation 的分部类。 Person 类由 EF 驱动。所以我必须创建一个元数据类来进行验证。

    [MetadataType(typeof(personMetadata))]
    public partial class person: EntityObject
    {
      public class personMetadata
      {
        [Required]
        [RegularExpression(@"[A-Za-z0-9]+")]       
        public object Name { get; set; }
      }
    }

编辑：添加引用的 javascript 文件。 “~/Scripts/jquery.validate.min.js” “~/Scripts/jquery.validate.unobtrusive.min.js”

原文

I'm using DataAnnotations to validate my input fields on a MVC3 application. I'm using regular expressions validations.
I get the validation messages on the UI for IE8 & IE9.
But I notice the difference when I hit the Save button even after the client side validation has failed.
IE9 keeps me on the client side.
On IE8 however, the control goes to the controller action, and I have to have a controller side TryValidateModel so that the validation errors out.

Does anyone know why IE8 is doing a server round trip?

Edit:
Adding the code. This goes into the cshtml.

    @using (Html.BeginForm("Person", "Account", FormMethod.Post))
    {
       <span class="resultError" id="resultError">
       @Html.ValidationMessageFor(model => model.Name, "Name should not contain special characters")  
       </span>
       <table>
         <tr>
          <td class="editor-label">Name:
          </td>
          <td class="editor-field">@Html.EditorFor(model => model.Name)
          </td>
        </tr>
       </table>
       <input type="submit" name="btnKey" value="Save" />
    }

This is the partial class using DataAnnotation. The Person class is driven by EF. So I have to create a metadata class to do the validation.

    [MetadataType(typeof(personMetadata))]
    public partial class person: EntityObject
    {
      public class personMetadata
      {
        [Required]
        [RegularExpression(@"[A-Za-z0-9]+")]       
        public object Name { get; set; }
      }
    }

"~/Scripts/jquery.validate.unobtrusive.min.js"
