本文章利用Ajax分页来简单讲述一下如何利用php与ajax实现数据无刷新分页功能，有需要的朋友可参考一下。

简单的mysql数据表结构

代码如下	复制代码
CREATE TABLE messages ( msg_id INT PRIMARY KEY AUTO_INCREMENT, message VARCHAR(150) );

JavaScript 代码

这里是ajax前段利用jquery来处理

代码如下

复制代码

function loading_show()
{
$('#loading').html("").fadeIn('fast');
}

function loading_hide()
{
$('#loading').fadeOut();
}

load_data.php

这里是获取由ajax发送的数据然后经过php查询mysql返回信息

代码如下

复制代码

if($_POST['page'])
{
$page = $_POST['page'];
$cur_page = $page;
$page -= 1;
$per_page = 15; // Per page records
$previous_btn = true;
$next_btn = true;
$first_btn = true;
$last_btn = true;
$start = $page * $per_page;
include"db.php";
$query_pag_data = "SELECT msg_id,message from messages LIMIT $start, $per_page";
$result_pag_data = mysql_query($query_pag_data) or die('MySql Error' . mysql_error());
$msg = "";
while ($row = mysql_fetch_array($result_pag_data))
{
$htmlmsg=htmlentities($row['message']); //HTML entries filter
$msg .= "

" . $row['msg_id'] . " " . $htmlmsg . "

";
}
$msg = "

" . $msg . "

"; // Content for Data
/* -----Total count--- */
$query_pag_num = "SELECT COUNT(*) AS count FROM messages"; // Total records
$result_pag_num = mysql_query($query_pag_num);
$row = mysql_fetch_array($result_pag_num);
$count = $row['count'];
$no_of_paginations = ceil($count / $per_page);
/* -----Calculating the starting and endign values for the loop----- */

//Some Code. Available in download script

}
?>
