如何判斷哪個圖像被點擊？

<%using (Html.BeginForm("ChangeLanguage", "AppController", FormMethod.Post)) 
{ %> 
    <div id="China"> 
     <input id="imageChina" name="btnsubmitLan" type="image" value="CN" alt='China' src="/Content/Image/IconHH/FlatCN.gif" /> 
    </div> 
    <div id="US"> 
     <input id="ImageUS" name="btnsubmitLan" type="image" value="US" alt='English' src="/Content/Image/IconHH/FlatUS.jpg" /> 
    </div> 
    <div id="VietNam"> 
     <input id="ImageVN" name="btnsubmitLan" type="image" value="VN" alt='VietNam' src="/Content/Image/IconHH/FlatVN.jpg" /> 
    </div> 
<%} %>

在控制器：如何判斷哪個圖像被點擊？

[AcceptVerbs(HttpVerbs.Post)] 
    public ActionResult ChangeLanguage(string btnsubmitLan, FormCollection form) 
    {//chu yeu load o phan template 

     if (btnsubmitLan != null) 
     { 
      switch (btnsubmitLan) 
      { 
       case "VN": Session["language"] = "VN"; break; 
       case "CN": 
       case "US": Session["language"] = "EN"; break; 

      } 
     } 
     return RedirectToAction("Index"); 
    }

但btnSubmit總是null。爲什麼？？？？

這個問題比較模糊。請細化。 –

你可以成爲什麼點擊圖像？ –

'form [「btnsubmitLan」]是否包含任何內容？ –

我會使用jQuery，然後做一個AJAX張貼到控制器傳入某種id。

<input id="ImageVN" name="btnsubmitLan" type="image" value="VN" alt='VietNam' src="/Content/Image/IconHH/FlatVN.jpg" /> 


$('input').click(function() { 
    var id = this.attr("id"); 
    //now do your ajax postback passing in the id. 
});
