Asp.Net+Javascript+CSS(模仿google的拖拽的个性网页布局) _操作数据库篇

个性网页布局的用到了2张表.具体的操作表的代码如下:(有4个文件)
Side.cs
 public class Side
 {
  int _SideID;
  string _SideLeft;
  string _SideCenter;
  string _SideRight;

  public Side()
  {
  }

  public int SideID
  {
   get{return this._SideID;}
   set{this._SideID=value;}
  }

  public string SideLeft
  {
   get{return this._SideLeft;}
   set{this._SideLeft=value;}
  }

  public string SideCenter
  {
   get{return this._SideCenter;}
   set{this._SideCenter=value;}
  }

  public string SideRight
  {
   get{return this._SideRight;}
   set{this._SideRight=value;}
  }

 }
}
WinInfo.cs

public class WinInfo
 {  
  int _WinID;
  string _WinName;
  int _WinFlag;
  public WinInfo()
  {
  }
  public int WinID
  {
   get{return this._WinID;}
   set{this._WinID=value;}
  }

  public string WinName
  {
   get{return this._WinName;}
   set{this._WinName=value;}
  }

  public int WinFlag
  {
      get{return this._WinFlag;}
         set{this._WinFlag=value;}
        }

 }

SideSql.cs
public class SideSql
 {
  public string conn=ConfigurationSettings.AppSettings["connstr"];

  public SideSql()
  {
  }
  /// <summary>
  /// 保存窗口的布局到数据库
  /// </summary>
  /// <param name="sideLeft">左侧布局容器的窗口的ID字符串,中间用逗号隔开</param>
  /// <param name="sideCenter">中间布局容器的窗口的ID字符串,中间用逗号隔开</param>
  /// <param name="sideRigth">右侧布局容器的窗口的ID字符串,中间用逗号隔开</param>
  /// <param name="sideID"></param>
  public void SaveSide(string sideLeft,string sideCenter,string sideRigth,int sideID)
  {
   using(SqlConnection con = new SqlConnection(conn))
   {
    con.Open();
    using(SqlTransaction trans=con.BeginTransaction())
    {
     try
     {
      SqlHelper.ExecuteNonQuery(trans,System.Data.CommandType.Text,"update Side set SideLeft='"+sideLeft+"',SideCenter='"+sideCenter+"',SideRight='"+sideRigth+"' where SideID="+sideID);
      trans.Commit();
     }
     catch
     {
      trans.Rollback();
     }
    }
   }

  }

  public Side InitSide(int sideID)//初始化窗口用的
  {
   
    using(SqlDataReader dr=SqlHelper.ExecuteReader(conn,System.Data.CommandType.Text,"select * from side where SideID=1"))
    {
     if(dr.Read())
      {
          Side TempSide=new Side();
       TempSide.SideLeft=dr["SideLeft"].ToString();
       TempSide.SideCenter=dr["SideCenter"].ToString();
       TempSide.SideRight=dr["SideRight"].ToString();
       return TempSide;
      }
      else
      {
       return null;
      }
    }

  }

 }

WinInfoSql.cs

public class WinInfoSql
 {
  public static string conn=ConfigurationSettings.AppSettings["connstr"];
        WinInfo TempWinInfo=new WinInfo();
  public WinInfoSql()
  {
  }

  public WinInfo GetWinInfo(int winID)//获取窗口信息
  {
   using(SqlDataReader dr=SqlHelper.ExecuteReader(conn,System.Data.CommandType.Text,"select * from WinInfo where WinFlag=1 and WinID="+winID))
   {
    if(dr.Read())
    {
     TempWinInfo.WinName=dr["WinName"].ToString();
     TempWinInfo.WinID=Convert.ToInt32(dr["WinID"]);
     return TempWinInfo;
    }
    else
    {
     return null;
    }
   }
  }
 }

 

 

该效果在firefox和IE中测试通过.拖动然后就布局自动保存到数据库里了.

SaveSide .aspx.cs 

public class SaveSide : System.Web.UI.Page
 {
  ahui4367.SideSql tempSideSql=new SideSql();
  private void Page_Load(object sender, System.EventArgs e)
  {
   if(Request.QueryString["action"]=="changeSide")
   {
    string strLeft=Request.QueryString["strleft"];
    string strCenter=Request.QueryString["strCenter"];
    string strRight=Request.QueryString["strRight"];
    tempSideSql.SaveSide(strLeft,strCenter,strRight,1);
   }
  }

  #region Web 窗体设计器生成的代码
  override protected void OnInit(EventArgs e)
  {
   //
   // CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。
   //
   InitializeComponent();
   base.OnInit(e);
  }
  
  /// <summary>
  /// 设计器支持所需的方法 - 不要使用代码编辑器修改
  /// 此方法的内容。
  /// </summary>
  private void InitializeComponent()
  {   
   this.Load += new System.EventHandler(this.Page_Load);

  }
  #endregion
 }

 

我把昨天的发表的代码又修改了.具体的看下面的/还使用了prototype1.4的框架了,

主要保存到数据库的代码在这里

  var leftContainer=$("c_1");
    var centerContainer=$("c_2")
    var rightContainer=$("c_3");
    var strLeft=strCenter=strRight="";
          Element.cleanWhitespace(leftContainer);
          Element.cleanWhitespace(centerContainer);
          Element.cleanWhitespace(rightContainer);
          for(var i=0;i<leftContainer.childNodes.length-1;i++)
          {
             strLeft=strLeft+leftContainer.childNodes[i].id.replace("m_","")+",";
          }
           for(var i=0;i<centerContainer.childNodes.length-1;i++)
          {
             strCenter=strCenter+centerContainer.childNodes[i].id.replace("m_","")+",";
          }
           for(var i=0;i<rightContainer.childNodes.length-1;i++)
          {
             strRight=strRight+rightContainer.childNodes[i].id.replace("m_","")+",";
          }
    var options={
    parameters:"strLeft="+strLeft.substr(0,(strLeft.length-1))+"&strCenter="+strCenter.substr(0,(strCenter.length-1))+"&strRight="+strRight.substr(0,(strRight.length-1)),
    method:"get"
    }
    new Ajax.Request("SaveSide.aspx?action=changeSide&s"+Math.random(),options);

只要把这段代码加入google_drag.js文件中,找到如下的地方.然后Paste

 if (this._afterDrag()) {

//这里就是放代码的地方

}
