c# - 从数据库的 html 页面添加值

Question

我使用 Microsoft Visual Studio 和 Microsoft sql server 2008。我创建了网站，我想添加用户在 sql 表上输入信息的文本值。我使用 Nhibarnate 和 FluentNhibernate。但是我的代码不能增值。我创建地图、实体以及如何从网页文本中添加价值。我可以为这个问题做些什么？

                });

        });
    </script>
}

和最后一个 Web.config。我在这部分做数据库和 w.studio 连接。

  <connectionStrings>
    <add name="DB" connectionString="server=A88;uid=ABC;pwd=123;database=DS"/>
  </connectionStrings>

动作.cs

using System;
using System.Collections.Generic;

using System.Web;
using Deneme.Entities;

namespace Deneme
{
    public class Actions
    {
        public bool SaveData(string AddressId, string FullName, string AddressLine1, string AddressLine2, string City, string State, string Zip, string Country)
        {
            Address adress = new Address();

            adress.City= City;
            adress.AddressLine1 = AddressLine1;
            adress.AddressLine2 = AddressLine2;
            adress.Country = Country;
            adress.FullName = FullName;
            adress.State = State;
            adress.Zip = Zip;
             return true;

        }
    }
}

其简单形式的答案是打开一个会话，开始一个事务然后提交。类似于以下内容：-

public bool SaveData(...)
{
  using (var session = Deneme.Config.FluentlyConfigure.SessionFactory.OpenSession())
  {
    using (var tran = session.BeginTransaction())
    {
      Address adress = new Address();
      adress.City= City;
      ...
      session.Save(address);
      tran.commit();
    }
  }

  return true;
}

看起来您可能需要重构您的FluentlyConfig类以公开SessionFactory. 您可能希望查看session-per-request以帮助您在 NHibernate 中进行会话管理。

另外，我会检查您的 AJAX POST，因为它看起来也不错。

我马上就可以看出你的 AJAX 调用是完全错误的。你只传入一个data对象。

$.ajax({
    type: "POST",
    url: path + "Default1/deneme",
    contentType: "application/json;charset=utf-8",
    data: { 
        FullName: "", 
        AddressLine1: "", 
        AddressLine2: "", 
        City: "", 
        State: "", 
        Zip: "", 
        Country: ""
    },
    success: function (data) {

    },
    error: function (xhr, ajaxOptions, thrownError) {
        $("#button1").removeAttr("disabled");
        alert(thrownError);
    }
});

然后，您需要将JsonResult deneme您的代码连接到其余代码。
