调用方法:<pre name="code" class="php">	$pager = new module_pager2( $total, $page_size);$page_html = $pager->gethtml();$page_url = $pager->geturl();

并将对应变量传递给前端页面：

<pre name="code" class="php">		$this->_view->assign('pager', 		 $page);$this->_view->assign('page_html', 	$page_html);$this->_view->assign('page_url', 	$page_url);$this->_view->assign('total', 	$total);

前端简单调用，这里是smarty模板的写法<div class="pageLine clearfix"><div class="fl pt5 pl5">共计<!--{$list_count}-->条记录</div><div class="pageItem clearfix fr"><div class="fl mr10"><!--{$page_html}--></div></div></div>然后写个最简单的样式：<style>.pageItem a{padding: 9px;border: 1px solid #E4DDDD;}.pageItem span{padding: 9px;border: 1px solid #E4DDDD;margin-right: 15px;background-color: rgb(107, 206, 115);}.pageItem > div{float:none;}</style>最后效果图：整体都很简单，在此做下笔记
