這篇文章主要介紹Jquery+Ajax+Json+存儲(chǔ)過程實(shí)現(xiàn)分頁，需要的朋友可以參考下

之前在做分頁時(shí)，很多朋友都是用Jquery分頁插件，之前我就用的jquery.paper，有需要的朋友可以聯(lián)系我，接下來小編給大家分享用Jquery+Ajax+Json+存儲(chǔ)過程實(shí)現(xiàn)高效分頁。

實(shí)現(xiàn)此功能用分頁存儲(chǔ)過程，pagination，js樣式，廢話不多了，具體請(qǐng)看下面代碼

分頁存儲(chǔ)過程：PAGINATION

CREATE PROCEDURE [dbo].[PAGINATION] 
 @FEILDS VARCHAR(),--要顯示的字段
 @PAGE_INDEX INT,--當(dāng)前頁碼
 @PAGE_SIZE INT,--頁面大小
 @ORDERTYPE BIT,--當(dāng)為時(shí) 則為 desc 當(dāng)為 時(shí) asc
 @ANDWHERE VARCHAR()='',--where語句 不用加where
 @ORDERFEILD VARCHAR(), --排序的字段
 @TABLENAME VARCHAR() --查詢的表明
 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 = --當(dāng)頁碼是第一頁時(shí)直接運(yùn)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   --以子查詢結(jié)果當(dāng)做新表時(shí) 要給表名別名才能用
           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)--這里要加括號(hào)
 END

分頁樣式：

<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>

首先創(chuàng)建一般處理程序，讀取數(shù)據(jù)庫中內(nèi)容，得到返回值.
創(chuàng)建文件，GetData.ashx.
我這里是用的存儲(chǔ)過程，存儲(chǔ)過程會(huì)再下面粘出來，至于數(shù)據(jù)只是實(shí)例，你們可根據(jù)需求自行讀取數(shù)據(jù)

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"];
      //判斷當(dāng)前索引存不存在，如果不存在則獲取記錄的總數(shù)。
      if (string.IsNullOrEmpty(pageIndex))
      {
        //獲取查詢記錄總數(shù)的sql語句
        int count = ;
        int.TryParse(new BLL.t_profit().SelectAllNum(), out count);
        context.Response.Write(count);
        context.Response.End();
      }
      //當(dāng)根據(jù)索引獲取數(shù)據(jù)
      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";//獲取所有的字段
        parms[].Value = pageIndex;//當(dāng)前頁面索引
        parms[].Value = ;//頁面大小
        parms[].Value = ;//升序排列
        parms[].Value = "";//條件語句
        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());//轉(zhuǎn)為Json格式
      }


 public string id { get; set; }
    public string name { get; set; } 
    public string sex { get; set; }
    public string tel { get; set; }

樣式代碼：

<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>

      $.post("GetData.ashx", null, function (data) {
        var total = data;
