MVC 5 - 在窗體（視圖）上輸入的值沒有傳遞給控制器​​

Question

我創建了一個View for表單提交，我希望表單數據在點擊Submit按鈕後傳遞給Controller。

爲了簡單起見，我按比例縮小了模型和視圖。

當我斷開HomeController並執行步驟： ReviewViewModel reviewViewModelx = reviewViewModel; 從我期望的形式填寫沒有值。

查看：

@model ReviewViewModel 


<div class="panel-body"> 
    @using (Html.BeginForm("SubmitReview", "Home", FormMethod.Post, new { model = Model })) 
     { 
     @*@Html.AntiForgeryToken()*@ 
     @Html.ValidationSummary("", new { @class = "text-danger" }) 
     <div class="form-horizontal"> 

       <div class="form-group"> 
        @Html.LabelForRequired(model => model.ReviewModel.Name, htmlAttributes: new { @class = "control-label col-md-5" }) 
        <div class="col-md-5"> 
         @Html.EditorFor(model => model.ReviewModel.Name, new { htmlAttributes = new { @class = "form-control" } }) 
         @Html.ValidationMessageFor(model => model.ReviewModel.Name, "", new { @class = "text-danger" }) 
        </div> 
       </div> 

       <div class="form-group"> 
        @Html.LabelForRequired(model => model.ReviewModel.Degree, htmlAttributes: new { @class = "control-label col-md-5" }) 
        <div class="col-md-5"> 
         @Html.EditorFor(model => model.ReviewModel.Degree, new { htmlAttributes = new { @class = "form-control" } }) 
         @Html.ValidationMessageFor(model => model.ReviewModel.Degree, "", new { @class = "text-danger" }) 
        </div> 
       </div> 

      <div class="form-group"> 
       <div class="col-md-offset-2 col-md-5"> 
        <input type="submit" value="Submit Review" class="btn btn-default" /> 
       </div> 
      </div> 
    </div> 
     </div> 
    } 

ReviewViewModel此視圖模型包含3個不同的數據模型，我只顯示下方，因爲這是正在被填充什麼複習課。

public class ReviewViewModel 
    { 
     public VideoTypeModel VideoTypeModel; 
     public VideoModel VideoModel; 
     public ReviewModel ReviewModel; 
     public ReviewViewModel() 
     { 
      VideoTypeModel = new VideoTypeModel(); 
      VideoModel = new VideoModel(); 
      ReviewModel = new ReviewModel(); 
     } 
     public ReviewViewModel(VideoTypeModel videoTypeModel, VideoModel videoModel, ReviewModel reviewModel) 
     { 
      this.VideoTypeModel = videoTypeModel; 
      this.VideoModel = videoModel; 
      if (reviewModel != null) 
      { 
       this.ReviewModel = reviewModel; 
      } 
     } 
    } 

評分數據模型：

ReviewModel

public class ReviewModel 
{ 

    [Required] 
    [Display(Name="Name: ")] 
    public string Name { get; set; } 

    [Required] 
    [Display(Name="Degree:")] 
    public string Degree { get; set; } 

} 

的HomeController
如前所述，第一步驟之後，有在reviewViewModelx.ReviewModel.Name沒有值或 reviewViewModelx.ReviewModel.Email（或模型中的任何其他字段爲I爲簡潔起見，在本樣本中刪除。

[HttpPost] 
public ActionResult SubmitReview(ReviewViewModel reviewViewModel) 
{ 
    ReviewViewModel reviewViewModelx = reviewViewModel; 
    SendReviewEmail ce = new SendReviewEmail(null); 
    SendReviewEmailToTech ste = new SendReviewEmailToTech(null); 
    return View(reviewViewModel); 
} 

我有點新手到MVC的，任何援助表示讚賞。提前致謝！

編輯：看來問題可能出現在您的ReviewViewModel中。我沒有一個MVC項目在我面前，但我認爲你可能錯過了你的getter和setter對象。你可以嘗試這樣的：

public class ReviewViewModel 
    { 
     public VideoTypeModel VideoTypeModel {get; set; } 
     public VideoModel VideoModel {get; set; } 
     public ReviewModel ReviewModel {get; set; } 
    }

在你的控制器，你需要添加郵政標籤。通常情況下，您將爲HttpGet和HttpPost執行一個操作

public ActionResult SubmitReview() 
{ 
    return View(); 
} 

[HttpPost] 
public ActionResult SubmitReview(ReviewViewModel reviewViewModel) 
{ 
    ReviewViewModel reviewViewModelx = reviewViewModel; 
    SendReviewEmail ce = new SendReviewEmail(null); 
    SendReviewEmailToTech ste = new SendReviewEmailToTech(null); 
    return View(reviewViewModel); 
}
