浏览次数：<span id="views"></span> 浏览次数只写上面一行吗？谢了没效果啊？

<script src="${resSys}/jquery.js" type="text/javascript"></script>
<script src="${resSys}/jqueryUI/jquery-ui.js" type="text/javascript"></script>
<script src="${resSys}/front.js" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
Cms.attachment("${base}","${content.id}","${content.attachments?size}","attach");
Cms.viewCount("${base}","${content.id}");
Cms.siteFlow("${base}", location.href, document.referrer);
});
</script>
还要有这些js

我加了JS和id 抛出这个异常  整个页面没有效果了

${content.id}  [in template "WEB-INF/t/cms/wzcg/wzcg/channel/bmdt.html" at line 22, column 29] 
栏目页不能加这个标签

额  但是项目有这个需求  可以改吗？

[@cms_content id='内容id']
${tag_bean.id}
[/@cms_content]
栏目页获取内容id只能这么获取

我是在栏目页遍历出该栏目下的所有内容  并显示每个内容的浏览次数  我页面上已经有了遍历内容的代码 之间将你刚才发的那段代码加到里面就OKl了吗？

栏目页显示内容次数又不需要js，只能从数据库里取

那用哪个标签显示出来呢

${a.views!}
