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,

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
}
