未顯示ASP.NET MVC驗證錯誤

Question

我正在使用tuples將多個模型加載到視圖中。

的視圖是爲

@using (Ajax.BeginForm(null, null, ajaxOptions, new { @class = "contact-form" })) 

     { 
      @Html.AntiForgeryToken() 
      <div class="form-group form-group--xs"> 
       @Html.TextBoxFor(m => m.Item2.Email, new { @class = "form-control input-sm", placeholder = "Your email address..." }) 
       @Html.ValidationMessageFor(m => m.Item2.Email) 
      </div> 
      <div class="form-group form-group--xs"> 
       @Html.TextAreaFor(m => m.Item2.Message, new { @class = "form-control input-sm", placeholder = "Your message...", rows = "4" }) 
       @Html.ValidationMessageFor(m => m.Item2.Message) 
      </div> 

      <input type="submit" class="btn btn-primary-inverse btn-sm btn-block" value="Send Your Message" /> 
     } 

控制器是

 [HttpPost] 
     [ValidateAntiForgeryToken] 
     public async Task<PartialViewResult> Submit([Bind(Prefix = "Item2")] ContactForm model) 
     { 
      bool isMessageSent = true; 

      if (ModelState.IsValid) 
      { 
       try 
       { 
        await Services.EmailService.SendContactForm(model); 
       } 
       catch (Exception ex) 
       { 
        isMessageSent = false; 
       } 
      } 
      else 
      { 
       isMessageSent = false; 
      } 
      return PartialView("_SubmitMessage", isMessageSent); 
     } 

和接觸形式是

public class ContactForm 
    { 
     [Required(ErrorMessage = "You must provide your email."), EmailAddress] 
     public string Email { get; set; } 

     [Required(ErrorMessage = "You must include a message.")] 
     public string Message { get; set; } 
    } 

最後的局部視圖是

@model bool 

@if (Model) 
{ 
    <div style="color:#c2ff1f">Your message has been sent.</div> 
} 
else 
{ 
    <div style="color:#f34141">An error occured while sending your message</div> 
} 

更新：的電子郵件文本呈現的HTML是

<input class="form-control input-sm" 
data-val="true" 
data-val-email="The Email field is not a valid e-mail address." 
data-val-required="You must provide your email." 
id="Item2_Email" 
name="Item2.Email" 
placeholder="Your email address..." 
type="text" 
value=""> 

如果我不輸入電子郵件字段或消息字段的任何文本，沒有發送消息:)但我沒有驗證在視圖中的錯誤:( 我在這裏做錯了什麼？

Answer 1

我想我需要休息一下。我失蹤

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

Answer 2

您正在返回一個沒有驗證錯誤消息代碼的partialView。

試試這個代碼：

 [HttpPost] 
     [ValidateAntiForgeryToken] 
     public async Task<PartialViewResult> Submit([Bind(Prefix = "Item2")] ContactForm model) 
     { 
      bool isMessageSent = true; 

      if (ModelState.IsValid) 
      { 
       try 
       { 
        await Services.EmailService.SendContactForm(model); 
       } 
       catch (Exception ex) 
       { 
        isMessageSent = false; 
       } 

      } 
      else 
      { 
       isMessageSent = false; 
       //Return the view that has validation error message display code. 
       return View(model); 
      } 
      return PartialView("_SubmitMessage", isMessageSent); 
     }
