1.html页面中

引入

<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>

2.pageGroup.css
