之前在做分页时，很多朋友都是用Jquery分页插件，之前我就用的jquery.paper，有需要的朋友可以联系我，接下来小编给大家分享用Jquery+Ajax+Json+存储过程实现高效分页。

实现此功能用分页存储过程，pagination，js样式，废话不多了，具体请看下面代码

分页存储过程：PAGINATION

CREATE PROCEDURE [dbo].[PAGINATION] @FEILDS VARCHAR(),--要显示的字段 @PAGE_INDEX INT,--当前页码 @PAGE_SIZE INT,--页面大小 @ORDERTYPE BIT,--当为时 则为 desc 当为 时 asc @ANDWHERE VARCHAR()='',--where语句 不用加where @ORDERFEILD VARCHAR(), --排序的字段 @TABLENAME VARCHAR() --查询的表明 as DECLARE @EXECSQL VARCHAR() DECLARE @ORDERSTR VARCHAR() DECLARE @ORDERBY VARCHAR() BEGIN set NOCOUNT on IF @ORDERTYPE = BEGIN SET @ORDERSTR = ' > ( SELECT MAX(['+@ORDERFEILD+'])' SET @ORDERBY = 'ORDER BY '+@ORDERFEILD+' ASC' END ELSE BEGIN SET @ORDERSTR = ' < ( SELECT MIN(['+@ORDERFEILD+'])' SET @ORDERBY = 'ORDER BY '+@ORDERFEILD+' DESC' END IF @PAGE_INDEX = --当页码是第一页时直接运行，提高速度 BEGIN IF @ANDWHERE='' SET @EXECSQL = 'SELECT TOP '+STR(@PAGE_SIZE)+' '+@FEILDS+' FROM '+@TABLENAME+' '+@ORDERBY ELSE SET @EXECSQL = 'SELECT TOP '+STR(@PAGE_SIZE)+' '+@FEILDS+' FROM '+@TABLENAME+' WHERE '+@ANDWHERE+' '+ @ORDERBY END ELSE BEGIN IF @ANDWHERE='' BEGIN --以子查询结果当做新表时 要给表名别名才能用 SET @EXECSQL = 'SELECT TOP'+STR(@PAGE_SIZE)+' '+@FEILDS+' FROM '+@TABLENAME+' WHERE '+@ORDERFEILD+ @ORDERSTR+' FROM (SELECT TOP '+STR(@PAGE_SIZE*(@PAGE_INDEX-))+' '+@ORDERFEILD+ ' FROM '+@TABLENAME+' '+@ORDERBY+') AS TEMP) '+ @ORDERBY END ELSE BEGIN SET @EXECSQL = 'SELECT TOP'+STR(@PAGE_SIZE)+' '+@FEILDS+' FROM '+@TABLENAME+' WHERE '+@ORDERFEILD+ @ORDERSTR+' FROM (SELECT TOP '+ STR(@PAGE_SIZE*(@PAGE_INDEX-))+' '+@ORDERFEILD+ ' FROM '+@TABLENAME+' WHERE '+@ANDWHERE+' '+@ORDERBY+') AS TEMP) AND '+@ANDWHERE+' '+ @ORDERBY END END EXEC (@EXECSQL)--这里要加括号 END

分页样式：

<style type="text/css"> a,area { -moz-outline-style: none; blr:expression(this.onFocus=this.blur()); text-decoration:none} div.badoo { padding:px; text-align:center; } div.badoo a { border:px solid #ededed; padding:px px; color:#; border-radius:px; margin-right:px;} div.badoo a:hover {border:px solid #ffa; color: #ffa; } div.badoo a:active {border:px solid #ffa; margin-right:px;} div.badoo span { border:px solid #EDEDED; padding:px px; color:#f;font-weight:bold; background:#FAFAFA; border-radius:px; margin-right:px;} div.badoo span.disabled { border:px solid #EDEDED; padding:px px; color:#; margin-right:px; font-weight:;} </style>

首先创建一般处理程序，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

using System; using System.Web; using System.Data.SqlClient; using System.Data; using System.Collections.Generic; using System.Web.Script.Serialization; using Model; context.Response.ContentType = "text/plain"; var pageIndex = context.Request["PageIndex"]; //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 int count = ; int.TryParse(new BLL.t_profit().SelectAllNum(), out count); context.Response.Write(count); context.Response.End(); } //当根据索引获取数据 else { int currentPageIndex = ; int.TryParse(pageIndex, out currentPageIndex); SqlParameter[] parms = new SqlParameter[] { new SqlParameter("@FEILDS",SqlDbType.NVarChar,), new SqlParameter("@PAGE_INDEX",SqlDbType.Int,), new SqlParameter("@PAGE_SIZE",SqlDbType.Int,), new SqlParameter("@ORDERTYPE",SqlDbType.Int,), new SqlParameter("@ANDWHERE",SqlDbType.VarChar,), new SqlParameter("@ORDERFEILD",SqlDbType.VarChar,) }; parms[].Value = "id,name,sex,tel";//获取所有的字段 parms[].Value = pageIndex;//当前页面索引 parms[].Value = ;//页面大小 parms[].Value = ;//升序排列 parms[].Value = "";//条件语句 parms[].Value = "id";//排序字段 List<Book> list = new List<Book>(); using (SqlDataReader sdr = Yoodor.DAL.SqlHelper.ExecuteReader(CommandType.StoredProcedure, "PAGINATION", parms)) { while (sdr.Read()) { list.Add(new Book { id = sdr[].ToString(), name = sdr[].ToString(), sex = sdr[].ToString(), tel = sdr[].ToString() }); } } context.Response.Write(new JavaScriptSerializer().Serialize(list).ToString());//转为Json格式 } public string id { get; set; } public string name { get; set; } public string sex { get; set; } public string tel { get; set; }

样式代码：

<style type="text/css"> a,area { -moz-outline-style: none; blr:expression(this.onFocus=this.blur()); text-decoration:none} div.badoo { padding:px; text-align:center; } div.badoo a { border:px solid #ededed; padding:px px; color:#; border-radius:px; margin-right:px;} div.badoo a:hover {border:px solid #ffa; color: #ffa; } div.badoo a:active {border:px solid #ffa; margin-right:px;} div.badoo span { border:px solid #EDEDED; padding:px px; color:#f;font-weight:bold; background:#FAFAFA; border-radius:px; margin-right:px;} div.badoo span.disabled { border:px solid #EDEDED; padding:px px; color:#; margin-right:px; font-weight:;} </style>

js代码

<script type="text/javascript"> $(function () { $.post("GetData.ashx", null, function (data) { var total = data; PageClick(, total, ); }); PageClick = function (pageIndex, total, spanInterval) { $.ajax({ url: "GetData.ashx", data: { "PageIndex": pageIndex }, type: "post", dataType: "json", success: function (data) { //索引从开始 //将当前页索引转为int类型 var intPageIndex = parseInt(pageIndex); //获取显示数据的表格 var table = $("#content"); //清楚表格中内容 $("#content tr").remove(); //向表格中添加内容 for (var i = ; i < data.length; i++) { table.append( $("<tr><td>" + data[i].id + "</td><td>" + data[i].name + "</td><td>" + data[i].sex + "</td><td>" + data[i].tel + "</td></tr>") ); } //for //创建分页 //将总记录数结果 得到 总页码数 var pageS = total if (pageS % == ) pageS = pageS / ; else pageS = parseInt(total / ) + ; var $pager = $("#pager"); //清楚分页div中的内容 $("#pager span").remove(); $("#pager a").remove(); //添加第一页 if (intPageIndex == ) { // $pager.append("<span>第一页</span>"); } else { // var first = $("<a href='javascript:void()' first='" + + "'>第一页</a>").click(function () { // PageClick($(this).attr('first'), total, spanInterval); // return false; // }); // $pager.append(first); } //添加上一页 if (intPageIndex == ) $pager.append("<span>上一页</span>"); else { var pre = $("<a href='javascript:void()' pre='" + (intPageIndex - ) + "'>上一页</a>").click(function () { PageClick($(this).attr('pre'), total, spanInterval); return false; }); $pager.append(pre); } //设置分页的格式 这里可以根据需求完成自己想要的结果 var interval = parseInt(spanInterval); //设置间隔 var start = Math.max(, intPageIndex - interval); //设置起始页 var end = Math.min(intPageIndex + interval, pageS)//设置末页 if (intPageIndex < interval + ) { end = ( * interval + ) > pageS ? pageS : ( * interval + ); } if ((intPageIndex + interval) > pageS) { start = (pageS - * interval) < ? : (pageS - * interval); } //生成页码 for (var j = start; j < end + ; j++) { if (j == intPageIndex) { var spanSelectd = $("<span>" + j + "</span>"); $pager.append(spanSelectd); } //if else { var a = $("<a href='javascript:void()'>" + j + "</a>").click(function () { PageClick($(this).text(), total, spanInterval); return false; }); $pager.append(a); } //else } //for //上一页 if (intPageIndex == Math.ceil(total / )) { $pager.append("<span>下一页</span>"); } else { var next = $("<a href='javascript:void()' next='" + (intPageIndex + ) + "'>下一页</a>").click(function () { PageClick($(this).attr("next"), total, spanInterval); return false; }); $pager.append(next); } //最后一页 if (intPageIndex == pageS) { // $pager.append("<span>最后一页</span>"); } else { // var last = $("<a href='javascript:void()' last='" + pageS + "'>最后一页</a>").click(function () { // PageClick($(this).attr("last"), total, spanInterval); // return false; // }); // $pager.append(last); } } //sucess }); //ajax }; //function }); //ready </script> <table id="content"> </table> <div id="pager"></div> /// <summary> /// Execute a SqlCommand that returns a resultset against the database specified in the connection string /// using the provided parameters. /// </summary> /// <param name="connectionString">一个有效的数据库连接字符串</param> /// <param name="cmdType">SqlCommand命令类型 (存储过程， T-SQL语句， 等等。)</param> /// <param name="cmdText">存储过程的名字或者 T-SQL 语句</param> /// <param name="commandParameters">以数组形式提供SqlCommand命令中用到的参数列表</param> /// <returns>A SqlDataReader containing the results</returns> public static SqlDataReader ExecuteReader( CommandType cmdType, string cmdText, params SqlParameter[] commandParameters) { SqlCommand cmd = new SqlCommand(); SqlConnection conn = new SqlConnection(connectionString); // we use a try/catch here because if the method throws an exception we want to // close the connection throw code, because no datareader will exist, hence the // commandBehaviour.CloseConnection will not work try { PrepareCommand(cmd, conn, null, cmdType, cmdText, commandParameters); SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection); cmd.Parameters.Clear(); return rdr; } catch (Exception ex) { conn.Close(); throw new Exception(ex.Message); } }

以上就是本文使用Jquery+Ajax+Json+存储过程实现高效分页的全部内容，希望大家喜欢。
