14 * example:
15 * 模式四种分页模式：
16 require_once('../libs/classes/page.class.php');
17 $page=new page(array('total'=>1000,'perpage'=>20));
18 echo 'mode:1
'.$page->show();
19 echo '
mode:2
'.$page->show(2);
20 echo '
mode:3
'.$page->show(3);
21 echo '
mode:4
'.$page->show(4);
22 开启AJAX：
23 $ajaxpage=new page(array('total'=>1000,'perpage'=>20,'ajax'=>'ajax_page','page_name'=>'test'));
24 echo 'mode:1
'.$ajaxpage->show();
25 采用继承自定义分页显示模式：
