ajax分页  php ajax分页   java ajax分页   asp.net ajax分页   jquery ajax 分页 jsp ajax无刷新分页   asp ajax分页   ajax 分页问题   ajax实现分页   ajax jsp分页
最就是php的result.php文件喽,:

<?php
//一系列从数据库的查询造作这里就不多说了....自己参考以下就知道了
//PHP服务端
/*
PHP分页函数
function Ajaxpage($sql,$num){
  global $db;
  $pageno=$_GET[pageno];
  $pageno=(int)$pageno;
  if(empty($pageno)||$pageno<1) $pageno=1;
  $result=$db->query($sql);
  $number=$db->num_rows($result);
  $totalpage=(int)ceil($number/$num);
  if($pageno>=$totalpage){$pageno=$totalpage;}
  $start_rowno=($pageno-1)*$num;
  $query=$sql." LIMIT ".$start_rowno.",".$num;
  $result=$db->query($query);
  return array(result=>$result,page=>array(pageno=>$pageno,totalpage=>$totalpage,number=>$number));
 }

$sql="select * from guest";//查询SQL语句
$num=2;//分页控制，每页显示2条记录
$return=Ajaxpage($sql,$num);
while($row=$db->fetch_assoc($return[result])){
 $result[]=$row; //这里可以用PHP处理下数据,这里就不举例了
}
$result=array(result=>$result,page=>$return[page]);
include(json.class.php);//包含JSON类文件
$json=& new Json();
$result=$json->encode($result);//JSON
echo $result;
*/
//假如根据AJAX发来pageno参数从数据库得到的资源经过JSON后是$str这个样子，直接输出，让JS处理.
//如果有什么不明白的可以问我
if(ob_get_length()) ob_clean();
header(cache-control:no-cache,must-revalidate);
header(pragma:no-cache);
if($_GET[pageno]==1)
