本文实例讲述了php+ajax实现无刷新分页实现方法。分享给大家供大家参考。具体如下：
limit 偏移量，长度;
limit 0,7; 第一页
limit 7,7; 第二页
limit 14,7; 第三页
每页信息条数：7
信息总条数：select count(*) from table
信息总页数：ceil向上取整(总条数/每页条数)
1、分页类具体使用
<?php
class Pagination {
private $total; //数据表中总记录数
private $listRows; //每页显示行数
private $limit; //mysql 数据库的limit
private $uri; //分页信息前面的uri地址
private $pageNum; //页数
private $config = array('header' => "个记录", "prev" => "【】", "first" => "【首 页】", "last" => "【尾 页】");
private $listNum = 8;
/*
* $total 当前信息总条数
* $listRows 每页显示的条数
* $pa 下面的page
http://网址/index.php?page=5
*/
public function __construct($total, $listRows = 10, $pa = "") {
$this->total = $total;
$this->listRows = $listRows;
$this->uri = $this->getUri($pa);
$this->page = !empty(<p>本文实例讲述了php+ajax实现无刷新分页实现方法。分享给大家供大家参考。具体如下：</p>
<p><span style="COLOR: #333333"><strong> limit 偏移量，长度;<br /> limit 0,7; 第一页<br /> limit 7,7; 第二页<br /> limit 14,7; 第三页<br /></strong></span>每页信息条数：7<br />信息总条数：select count(*) from table<br />信息总页数：ceil向上取整(总条数/每页条数)<br /><strong>1、分页类具体使用<br /></strong></p>

2 数据显示
<?php
//链接数据库
//获得具体信息
//分页显示
header("content-type:text/html;charset=utf-8");
$link = mysql_connect('localhost','root','111111');
mysql_select_db('shop', $link);
mysql_query("set names utf8");
$css = <<<eof
<style type="text/css">
table {border:1px solid black; width:700px; margin:auto; border-collapse:collapse;}
td {border:1px solid black; }
</style>
eof;
echo $css;
echo "
<table>
<tr><td>序号</td><td>名称</td><td>数量</td><td>价格</td><td>时间</td></tr>
";
//1 引入分页类
include "./Pagination.php";
//2. 获得信息总条数
$sql = "select * from sw_goods";
$qry = mysql_query($sql);
$total = mysql_num_rows($qry);
$per = 7;
//3. 实例化分页类对象
$page_obj = new Pagination($total,$per);
//4. 拼装sql语句，获得每页信息
//利用page_obj实现limit的灵活设置
//$page_obj -> limit;
$sqla = "select * from sw_goods ".$page_obj->limit;
$qrya = mysql_query($sqla);
//5. 获得页面列表
$pagelist = $page_obj -> fpage(array(3,4,5,6,7,8));
$i=1;
while($rsta = mysql_fetch_assoc($qrya)){
echo "<tr>";
echo "<td>".$i++."</td>";
echo "<td>".$rsta['goods_name']."</td>";
echo "<td>".$rsta['goods_number']."</td>";
echo "<td>".$rsta['goods_price']."</td>";
echo "<td>".date("Y-m-d H:i:s",$rsta['goods_create_time'])."</td>";
echo "</tr>";
}
echo "<tr><td colspan=5>".$pagelist."</td></tr>";
echo "</table>";
