更改值不工作

我使用下面的代碼（mvc5），它應該做的基本的東西，但currenlty沒有工作... 有下拉列表框，當用戶從dev的選擇改變爲生產的用戶和passowrd應該是啓用和用戶可以把值（通過嘲笑與Dev它應該灰色），這是我在模型和創建視圖中的代碼cshtml，任何想法我是什麼想念這裏，我新到這個話題，所以它可以從基本... everymost ...更改值不工作

我添加Nugat爲Jquery ...

我也試着把調試器;腳本並沒有停止......

這是模型類

    {

     public string User { get; set; } 

     public string Password { get; set; } 
     public string SelectedType { get; set; } 

     public IEnumerable<SelectListItem> Type 
     { 
      get 
      { 
       return new[] 
       { 
        new SelectListItem {Value = "D", Text = "Dev"}, 
        new SelectListItem {Value = "p", Text = "Production"} 
       }; 
      } 
     } 
    } 


    public class AdDBContext : DbContext 
    { 
     public DbSet<Ad> Ad { get; set; } 
    } 
}

編輯這是生成的HTML

你能發佈生成HTML只是爲了確定？ – Incognito

@ Kuma-你是什麼意思生成的HTML，讓我知道如何得到它，我會發布它... –

@Kuma - 此外，我把調試;在開始的腳本中，它並沒有停止... –

當你寫@Html.DropdownFor(model=>model.SelectedType,...) select元素的名稱應該是SelectedType本質上不是Type！因此，如下

$(document).ready(function() { 

    $('select[name="SelectedType"]').change(function() { 

     if ($(this).val() === 'Production') { 

      $('input[name="User"]').prop("disabled", true); 
      $('input[name="Password"]').prop("disabled", true); 
     } 

     else { 
      $('input[name="User"]').prop("disabled", false); 
      $('input[name="Password"]').prop("disabled", false); 
     } 

    }); 
});

編輯修改您的JS代碼：請刪除您的兩行代碼，你導入jQuery和jQueryUI的庫兩次

感謝Bellash，我嘗試了它，並沒有正常工作......另外我把關鍵字調試器;在腳本的開頭爲文檔準備好了，它不會停止，有什麼想法？ –

這是因爲你導入jquery和jqueryui庫兩次！請刪除這兩行' ' – Bellash

我已經刪除它們，仍然不工作....不停止在調試器中...我也試圖做相反的事情，如刪除第一個，保持第二個，不工作.. –
