如果说您没用过这些东东的话,我相信看完这篇博文会对您有帮助的,,如果有任何问题不懂或者有bug没问题,欢迎随时联系我,
同时也欢迎高手多给点意见,我不建议在喷子中成长。

前言
相信很多朋友都用过,Jquery的分页插件,我之前就用的jquery.paper这个,如果有兴趣可以留下QQ,我发份简单的实例源码给您。
该代码是晚上匆忙中完成的,所以没怎么优化,但是主要作为实例来结合这些知识的一个综合运用。好了废话不多说,直接上代码。

首先我们创建一般处理程序,来读取数据库中内容,得到返回值.
创建文件,GetData.ashx.
我这里是用的存储过程,存储过程会再下面粘出来,至于数据只是实例,你们可根据需求自行读取数据
代码如下:
<%@ WebHandler Language="C#" Class="GetData" %>

var pageIndex = context.Request["PageIndex"];
string connectionString = @"Data Source=KUSE\SQLEXPRESS;Initial Catalog=bookshop;Integrated Security=True";
//判断当前索引存不存在,如果不存在则获取记录的总数。
if (string.IsNullOrEmpty(pageIndex))
{
//获取查询记录总数的sql语句
string sql = "select count(-1) from books";
int count = 0;
int.TryParse(SqlHelper.ExecuteScalar(connectionString, System.Data.CommandType.Text, sql, null).ToString(), out count);
context.Response.Write(count);
context.Response.End();
}
//当根据索引获取数据
else

};
parms[0].Value = "*";//获取所有的字段

运行效果图
补充:
终于,大功告成,不容易啊!有几个地方忘记给注释说明了,大家可能不理解。
PageClick(1, total, 3); 这个函数,第一个参数是当前页码,第一调用为第一页,这个不用管,total:表示总记录数,第三个参数表示:当前索引和旁边个间隔几页
OK,今天到此为止,第一次写东东,写的不好,技术含量也有限,忘读此博文者见谅。
