哪个版本系统

vcms8.1 版本

你内容引用了哪个模板

自己新建的 模板

收藏代码如下：
<script type="text/javascript">
$(function() {
Cms.checkPerm("${base}","${content.id}");
Cms.collectCsi("${base}","collectCsiDiv","collect_csi","${content.id}");
Cms.attachment("${base}","${content.id}","${content.attachments?size}","attach");
Cms.viewCount("${base}","${content.id}");
Cms.siteFlow("${base}", location.href,document.referrer,"${site.config.flowSwitch?string}");
});
</script>

<script type="text/javascript">
function shouCang(){
[#if user??]
Cms.collectexist("${base}","${content.id}","cancelSpan","comfirmSpan");
    $("#comfirmSpan").click(function(){
Cms.collect("${base}","${content.id}",1,"cancelSpan","comfirmSpan");
    });
    $("#cancelSpan").click(function(){
      Cms.collect("${base}","${content.id}",0,"cancelSpan","comfirmSpan");
    });
[#else]
alert("请登录！");
[/#if]
};
</script>

弹框关不掉说明你写的模板有问题啊，你部署环境说下

JDK1.7
tomcat 1.7

eclipse开发

你用部署包部署试下看
