ajax+php实现无刷新分页代码实例

更新时间：2026-09-29 19:37:42作者：sa

index.php代码如下:

header("content-type: text/html; charset=utf-8");

error_reporting(e_all^e_notice);

include('pagination_class.php');

mysql_connect('localhost', 'root', '') or die(mysql_error());

mysql_select_db('mydemo');

mysql_query("set names 'utf8'");

$qry = "select * from students";

$searchtext = "";

if($_request['search_text']!=""){

$searchtext = $_request['search_text'];

$qry .=" where name like '$searchtext%'";

}

//for pagination

$starting=0;

$recpage = 2;//number of records per page

$obj = new pagination_class($qry,$starting,$recpage);
$result = $obj->result;

?><form name="form1" action="testpage.php" method="post">

<tr>

search <input type="text" name="search_text" id="search_text" value="<?php echo $searchtext; ?>">

</td>

</tr>

<?if(mysql_num_rows($result)!=0){

$counter = $starting + 1;

while($data = mysql_fetch_array($result)) {?>

<tr>

</tr><?

$counter ++;

} ?>

<tr><td colspan="2"><? echo $obj->anchors; ?></td></tr>

<tr><td colspan="2"><? echo $obj->total; ?></td></tr>

<?}else{?>//开源代码www.bcty365.com

<tr><td align="center" colspan="2">no data found</td></tr>

<?}?>

</td></tr>

</table>

</div>

</td></tr>

</table></form>

pagination.js文件,代码如下:

function $()

{

var elements = new array();

for (var i = 0; i < arguments.length; i++)

{

var element = arguments[i];

if (typeof element == 'string')

element = document.getelementbyid(element);

if (arguments.length == 1)

return element;

elements.push(element);

}

return elements;

}

var xmlhttp

function pagination(page)

{

xmlhttp=getxmlhttpobject();

if (xmlhttp==null)

{

alert ("your browser does not support ajax!");

return;

}

var url="test_sub.php";

url = url+"?starting="+page;

url = url+"&search_text="+$('search_text').value;

url=url+"&sid="+math.random();

xmlhttp.onreadystatechange=statechanged;

xmlhttp.open("get",url,true);

xmlhttp.send(null);

}

function statechanged()

{

if (xmlhttp.readystate==4)

{

$("page_contents").innerhtml=xmlhttp.responsetext;

}

function getxmlhttpobject()

{

var xmlhttp=null;

try

{

// firefox, opera 8.0+, safari

xmlhttp=new xmlhttprequest();

}

catch (e)

{

// internet explorer

try

{

xmlhttp=new activexobject("msxml2.xmlhttp");

}

catch (e)

{

xmlhttp=new activexobject("microsoft.xmlhttp");

}

return xmlhttp;

}

pagination_class.php,代码如下:

<?php

you can use it with out any worries...it is free for you..it will display the out put like:

first | previous | 3 | 4 | 5 | 6 | 7| 8 | 9 | 10 | next | last

page : 7 of 10 . total records found: 20

class pagination_class{

var $result;

var $anchors;

var $total;

function pagination_class($qry,$starting,$recpage)

{

$rst = mysql_query($qry) or die(mysql_error());

$numrows = mysql_num_rows($rst);

$qry .= " limit $starting, $recpage";

$this->result = mysql_query($qry) or die(mysql_error());

$next = $starting+$recpage;

$var = ((intval($numrows/$recpage))-1)*$recpage;

$page_showing = intval($starting/$recpage)+1;

$total_page = ceil($numrows/$recpage);

if($numrows % $recpage != 0){

$last = ((intval($numrows/$recpage)))*$recpage;

}else{

$last = ((intval($numrows/$recpage))-1)*$recpage;

}

$previous = $starting-$recpage;

$anc = "<ul id='pagination-flickr'>";

if($previous < 0){

$anc .= "<li class='previous-off'>first</li>";

$anc .= "<li class='previous-off'>previous</li>";

}else{

$anc .= "<li class='next'><a href='网页特效:pagination(0);'>first </a></li>";

$anc .= "<li class='next'><a href='javascript：pagination($previous);'>previous </a></li>";
}

################if you dont want the numbers just comment this block###############
$norepeat = 4;//no of pages showing in the left and right side of the current page in the anchors
$j = 1;

$anch = "";

for($i=$page_showing; $i>1; $i--){
$fpreviouspage = $i-1;

$page = ceil($fpreviouspage*$recpage)-$recpage;
$anch = "<li><a href='javascript：pagination($page);'>$fpreviouspage </a></li>".$anch;

if($j == $norepeat) break;

$j++;

}

$anc .= $anch;

$anc .= "<li class='active'>".$page_showing."</li>";

$j = 1;

for($i=$page_showing; $i<$total_page; $i++){
$fnextpage = $i+1;
