提交給控制給出空值

Question

我是mvc的新手，我希望從代碼後面訪問一個文本框值的值，我認爲這是通過將值作爲參數傳遞給我的邏輯方法行動結果，但是當我調試firstName其顯示爲空？。

這是我試圖訪問這個值請原諒我的無知我來自一個長的webforms背景。

<input id="firstName" class="form-control" type="text" /> 

而且相對於控制器快速quesiton必須我總是返回一個視圖，它是從我能打了個比方去回報第二步，只要它具有相同的佈局文件？如何告訴它去另一個視圖，而不是保存操作原因，我問的是我正在做一個嚮導表單。

我的形式標記

      </select> 

     </div> 
    </div> 
    <button type="submit" id="btnSave">Save</button> 



} 

我的控制器操作結果：

public ActionResult Step1(string firstName) 
    { 
     DataAccessAdapter _adapter = new DataAccessAdapter(); 

     TblfhcsPersonalEntity _personal = new TblfhcsPersonalEntity(); 

     _personal.FirstName = firstName; 



     _adapter.SaveEntity(_personal, true); 




     return View(); 

    }

對於任何形式的HTML提交數據，所有<input>標籤必須有一個name="..."屬性。設置id對JavaScript很有用，但在表單提交時忽略。

在這種情況下，name="firstName"將是一個很好的開始，因爲它符合您在Controller操作方法Step1中綁定的內容。
