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'");

?>

<script language="javascript" src="pagination.js"></script>

<link rel="stylesheet" type="text/css" href="style.css" />

<?

$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">



   <table border="1" align="center" width="40%">

   </tr>

   <tr><td colspan="2">



   <div id="page_contents">

    <tr><td>sl no</td><td>name</td></tr>

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

     $counter = $starting + 1;

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

      <tr>

    <?}else{?>//开源代码phpfensi.com

    <?}?>

    </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:

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--){

   $page = ceil($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++){

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

  }

   $anc .= "</ul>";

  $this->anchors = $anc;



  $this->total = "page : $page_showing <i> of  </i> $total_page . total records found: $numrows";

}

}

?>
