<link rel="stylesheet" type="text/css" href="/stylesheets/pageGroup.css">
<script src="/javascripts/web/pageGroup.js" type="text/javascript"></script>

<div id="pageGro" class="cb">
{{if maxPage>0}}//总页数
<div class="pageUp">上一页</div>
<div class="pageList">
<ul>
</ul>
</div>
<div class="pageDown">下一页</div>{{/if}}
<div id="countPage" style="display:none">{{maxPage}}</div>//总页数
<div id="nowPage" style="display:none">{{page}}</div>//当前页
<div id="title" style="display:none">{{title}}</div>//标题
</div>
