在單擊視圖表增加列數據庫

所以我有一個名爲AnonymousComment數據庫表，包含以下信息：在單擊視圖表增加列數據庫

[Id] INT IDENTITY (1, 1) NOT NULL, 
    [Title] VARCHAR (50) NULL, 
    [Comment] TEXT NULL, 
    [AgreeNumber] INT NULL, 
    [MetaId] VARCHAR (50) NULL, 
    [UserFeeling] TEXT NULL, 
    [AnonymousDate] DATETIME NULL,

然後，我有一個觀點（指數）顯示所有行（匿名評論），顯示每個評論的標題，然後當你點擊標題，它顯示標題，UserFeeling（表情）和評論在彈出的模態如圖片所示下面

該指數的代碼視圖如下

@using System.Web.UI.WebControls 
    @using Siza.Models 
    @model IEnumerable<Siza.Models.AnonymousComment> 

    @{ 
    ViewBag.Title = "Siza Anonymous"; 
    Layout = ""; 
    }

笏我想要做的，是在增量和減量模式中的類似按鈕onclick之間切換。所以當你點擊類似按鈕時，它會將該編號的AgreeNumber列遞增1，然後變成不一樣。然後，如果你點擊不同按鈕，它將該列減1。

我想有點擊調用JavaScript函數執行肚裏沿線的東西這個

@{ 
    using (var context = new SizaData_1Entities()){ 
    context.AnonymousComments.SqlQuery("UPDATE dbo.AnonymousComment SET AgreeNumber = AgreeNumber - 1 WHERE Id =" + item.Id); 
    } 

    }

此問題的另一個弧線球是每一行創建的事實原始的SQL語句與每個項目一個。

幫助將不勝感激

在此先感謝

你需要寫一個JavaScript來做一個Ajax調用，當有人喜歡或不喜歡是clicke d，將相關數據傳遞給服務器，如記錄Id和+1或-1，然後在您的控制器中，您可以使用linq或執行存儲過程來更新數據庫，**絕不使用內聯查詢** –

感謝您的答覆。你是否會提供一些示例代碼來說明如何去做這件事。 –

我希望以下的答案將會有助於你

像創建2圖像不像

剃刀

<img id="likeImg" src="~/image/like.png" /> 
<img id="unLikeImg" src="~/image/unlike.png" />

次訪問通過Ajax調用

阿賈克斯

$(function() { 
    $("#likeImg").click(function() { 
     $.ajax({ 
      url: '/Home/SetLike', 
      contentType: 'application/json; charset=utf-8', 
      type: 'POST', 
      cache: false, 
      success: function (result) { 
       // Success Statement 
      }, 
      error: function (xhr, status, error) { 
       alert("Error"); 
      } 
     }); 
    }); 

    $("#unLikeImg").click(function() { 
     $.ajax({ 
      url: '/Home/SetUnLike', 
      contentType: 'application/json; charset=utf-8', 
      type: 'POST', 
      cache: false, 
      success: function (result) { 
       // Success Statement 
      }, 
      error: function (xhr, status, error) { 
       alert("Error"); 
      } 
     }); 
    }); 
});

在控制器動作控制器動作寫函數像不像

控制器

public void SetLike() 
    { 
     // Like Code here 
    } 

    public void SetUnLike() 
    { 
     // Unlike code here 
    }
