Url.Action不傳遞參數指標

在我的控制，我有以下代碼：Url.Action不傳遞參數指標

public ActionResult Index(int? videoId, int languageId = 0) 
     { 

       //Some code 
     }

然後在我的.chtml頁我引用它，像這樣：

@using (Html.BeginForm("Index", "VideoLanguage", FormMethod.Post)) 
{ 
    @Html.Hidden("videoId", Model.VideoId) 
    @Html.Hidden("videoLanguageId", Model.SelectedLanguage.LanguageId) 

    <div> 
     @Html.DropDownListFor(model => model.SelectedLanguage.LanguageId, ViewData["LanguageId"] as SelectList) 
    </div> 
    <div> 
      <a href="@Url.Action("Index", "VideoLanguage",new { videoId = Model.VideoId, languageId = Model.SelectedLanguage.LanguageId })" class="linkbutton">Add Language</a> 
    </div> 

... code keeps going

會發生什麼時我點擊按鈕，從下拉列表中選擇的LanguageId值不會被傳遞。原始值是。

你不這樣做是正確的。你能在這裏發佈你的模型的代碼嗎？如果你這樣做，我會告訴你如何以正確的方式做到這一點。 – ataravati

<a href="@Url.Action("Index", "VideoLanguage",new { videoId = Model.VideoId, languageId = Model.SelectedLanguage.LanguageId })" class="linkbutton">Add Language</a>

是當頁面加載，所以在HTML中的值將被硬性規定，你需要做的是無論是在JavaScript設置的超級鏈接參數或使用：

<input type="submit" value="Index" />

這個答案幫助我瞭解問題所在。謝謝。 –

試試這個：

@using (Html.BeginForm("Index", "VideoLanguage", FormMethod.Post, new { videoId = Model.VideoId, languageId = Model.SelectedLanguage.LanguageId })) 
{ 
    .... 
}

你應該通過您的PARAMS到@Html。 BeginForm幫手，只是提交表單

@using (Html.BeginForm("Index", "VideoLanguage", FormMethod.Post, new { videoId = Model.VideoId, languageId = Model.SelectedLanguage.LanguageId })) 
{ 
    @Html.Hidden("videoId", Model.VideoId) 
    @Html.Hidden("videoLanguageId", Model.SelectedLanguage.LanguageId) 

    <div> 
     @Html.DropDownListFor(model => model.SelectedLanguage.LanguageId, ViewData["LanguageId"] as SelectList) 
    </div> 
    <div> 
     <input type="submit" value="Add Language"/> 
    </div> 

... code keeps going 
}

在你的控制器，你也應該有兩種方法獲取和使用相同的名稱設置：

public ActionResult Index() 
     { 
//Here just get a view 
     } 

[HttpPost] 
public ActionResult Index(int? videoId, int languageId = 0) 
     { 
//Here code to save in database 
     }
