单击视图以增加表中数据库的列

Question

因此，我有一个名为AnonymousComment的数据库表，其中包含以下详细信息：

[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,

然后，我有一个显示所有行（匿名评论）的视图（索引），显示每个评论的标题，然后单击标题时，它以弹出模式显示标题，UserFeeling（表情符号）和评论，如图所示在下面的图片中

索引视图的代码如下

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

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

  </div>

  </div>
  </div>



  <span class="wrapper" data-toggle="modal" data-target="#@item.Id">
  <div class="textwrap">
  @Html.DisplayFor(modelItem => item.Title)
  </div>
  <span class="tooltip">
  <div align="center">
  <i class="@item.UserFeeling"></i><br />
  <img src="http://pikcle.com/experiments/demo/skype/experiments/trans.png" class="emoticon thumbsup" title="thumbsup" /> Likes:@item.AgreeNumber 

  </div>
  </span>
  </span>
  }
  </div>

我想做的是，在模态中的like按钮的onclick的递增和递减之间进行切换。 因此，当您单击“ like”按钮时，它将为该特定行将AgreeNumber列增加一，然后变为不相同。 然后，如果您单击“ likely”按钮，它将使该行的列减1。

我当时想单击以调用一个javascript函数，该函数执行一个原始sql语句，其内容与此相似

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

  }

解决此问题的另一个方法是，为每个项目创建一个行。

帮助将不胜感激

希望以下答案对您有帮助

创建2个喜欢和不同的图片

剃刀

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

通过ajax调用访问控制器操作

阿贾克斯

$(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");
            }
        });
    });
});

在控制器动作中为喜欢和不喜欢写函数

控制者

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

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