Question

我想在表单上实现客户端验证，但是当我不放置数据时，没有显示所需的错误消息。脚本已正确加载到布局文件中。在其余视图中，必填消息将正确显示，并且程序可以正常运行。我已将此主题的代码发送给附件。

控制器：

  <HttpPost()>
        Function GalleryFiles1(ByVal docs As MachininfoDocs, ByVal imgUp As HttpPostedFileBase) As ActionResult
            If ModelState.IsValid Then
                If imgUp IsNot Nothing And IsImage(imgUp) Then
                    docs.FileName = Guid.NewGuid().ToString() & Path.GetExtension(imgUp.FileName)
                    docs.DocGroup = 1
                    docs.MachininfoID = PVMachinInfoId

                    imgUp.SaveAs(Server.MapPath("/Images/MachinImages/" & docs.FileName))
                    Dim img As New ImageResizer()
                    img.Resize(Server.MapPath("/Images/MachinImages/" & docs.FileName), Server.MapPath("/Images/MachinImages/Thumb/" & docs.FileName))
                    db.MachininfoDocs.Add(docs)
                    db.SaveChanges()
                End If
            End If
            Return RedirectToAction("GalleryFiles1", New With {Key .id = docs.MachininfoID})
        End Function

一个常见的错误是谁使用mvc默认捆绑软件而忘记将捆绑软件导入布局中

@Scripts.Render("~/bundles/jqueryval")

此外，您还应该在web.config应用程序设置中激活它们

<appSettings>
  <add key="UnobtrusiveJavaScriptEnabled" value="true" />
  <add key="ValidationSettings:UnobtrusiveValidationMode" value="none" />

客户端必需错误消息未显示
