    /**是否有上一页**/
    public $hasPrePage = true;
    /**是否有下一页**/
    public $hasNextPage = true;
    
    public $pageNoList = array();

 2、分页类使用实例代码

<?php
include 'PageView.php';
header("Content-type:text/html;charset=utf-8");
$pageNo = $_GET['page'];
$pageSize = 1;
//分页数据
$pageData = array (array ('id' => 1 ), array ('id' => 2 ), array ('id' => 3 ), array ('id' => 4 ) );
//取得总行数
$count = 21;
$test = array('type'=>1,'name'=>'add');

$pageUrl = '';
$pageUrl = 'javascript:tabPage';

//$pageParameterArray = null;
$pageParameterArray = array('id'=>1,'type'=>'add');

//创建分页器
$p = new PageView ( $count, $pageSize, $pageNo, $pageData ,$pageUrl,$pageParameterArray);
//生成页码
$pageViewString = $p->echoPageAsDiv ();
$pageData = $p->pageData;
echo '<style type="text/css">
<!--

</style>';
echo $pageViewString;
echo "<script type='text/javascript' src='/test/jquery.min.js'></script>
	<script type='text/javascript'>
	function tabPage(tid,id,type){
	alert(tid);
