jquery pagination插件实现无刷新分页代码_jquery

string strConn = ConfigurationManager.AppSettings["ConnectionString"];
//具体的页面数
int pageIndex;    
int.TryParse(context.Request["pageIndex"], out pageIndex);
//排序的依据
string orderType = "ProductID";
int sortType = 1;
if (!string.IsNullOrEmpty(context.Request["sortType"]))
{
string[] strArr = context.Request["sortType"].Split('_');
if (strArr[1] == "0")
{
orderType = strArr[0];
sortType = 0;
}
else
{
orderType = strArr[0];
sortType = 1;
}
}
if (pageIndex == 0)
{
pageIndex = 1;
}
//下面就是分页的存储过程了，把相应的参数传进去就可以了。
System.Data.SqlClient.SqlParameter[] p =
{
SqlHelper.MakeOutParam("@Counts", SqlDbType.Int, 4),
SqlHelper.MakeInParam("@tblName", SqlDbType.VarChar, 128, "Products"),
SqlHelper.MakeInParam("@strGetFields", SqlDbType.VarChar,200, "ProductName,QuantityPerUnit"),
SqlHelper.MakeInParam("@fldName", SqlDbType.VarChar, 128, orderType),
SqlHelper.MakeInParam("@PageSize", SqlDbType.Int, 4, 20),
SqlHelper.MakeInParam("@PageIndex", SqlDbType.Int, 1, pageIndex),
SqlHelper.MakeInParam("@OrderType", SqlDbType.Bit, 1, sortType),
SqlHelper.MakeInParam("@strWhere", SqlDbType.VarChar, 1500, "")
};
DataTable dt = SqlHelper.ExecuteDataset(strConn, CommandType.StoredProcedure, "sp_PageCut", p).Tables[0];
int pageCount = Convert.ToInt32(p[0].Value.ToString());
//将得到的数据转换成json
context.Response.Write(Util.DataTableToJSON(dt, "Products", pageCount));
下面我们看看DataTableToJson这个方法的代码，这个比较简单，我也是看它的帮助文档写出来的，代码的详细说明就不说了。

public static string DataTableToJSON(DataTable dt, string tableName, int pageCount)
{
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
using (JsonWriter jw = new JsonTextWriter(sw))
{
JsonSerializer ser = new JsonSerializer();
jw.WriteStartObject();
jw.WritePropertyName(tableName);
jw.WriteStartArray();
#region TableName属性
foreach (DataRow dr in dt.Rows)
{
jw.WriteStartObject();
foreach (DataColumn dc in dt.Columns)
{
jw.WritePropertyName(dc.ColumnName);
ser.Serialize(jw, dr[dc].ToString());
}
jw.WriteEndObject();
}
#endregion
jw.WriteEndArray();
jw.WriteEndObject();
sw.Close();
jw.Close();
}
return sb.ToString();
}

$("#Pagination").pagination(这个就是起到了记录总数的作用。
if (!IsPostBack)
{
SqlParameter[] p =
{
SqlHelper.MakeOutParam("@Counts", SqlDbType.Int, 4),
SqlHelper.MakeInParam("@tblName", SqlDbType.VarChar, 128, "Products"),
SqlHelper.MakeInParam("@strGetFields", SqlDbType.VarChar,200, "*"),
SqlHelper.MakeInParam("@fldName", SqlDbType.VarChar, 128, "ProductID"),
SqlHelper.MakeInParam("@PageSize", SqlDbType.Int, 4, 20),
SqlHelper.MakeInParam("@PageIndex", SqlDbType.Int, 1, 1),
SqlHelper.MakeInParam("@OrderType", SqlDbType.Bit, 1, 0),
SqlHelper.MakeInParam("@strWhere", SqlDbType.VarChar, 1500, "")
};
DataTable dt = SqlHelper.ExecuteDataset(conn, CommandType.StoredProcedure, "sp_PageCut", p).Tables[0];
pageCount = Convert.ToInt32(p[0].Value.ToString());
}
