为什么我的第三方控件Accordion在某些机器上不能用，报JavaScript错误‘未指明的错误’。

            </cc1:Accordion>大哥。大姐们麻烦你们检查哈撒。我看了几遍都没错误啊！！在有些机器上能够正常运行，为什么在有些机器上又报‘未指明的错误呢’  我都弄了好几天了谢谢啦！！！我怀疑是web.config 文件中<globalization requestEncoding="gb2312" responseEncoding="gb2312"/>编码的问题。因为在编码为GB2312时在一个页面报‘ajax框架未加载’、‘sys未定义’等错误,我把编码改为utf-8后这个页面错误消失,但是Accordion控件任然不能展开！！！！  
  请各位分析下啊！！！！！  问题到底是在哪里啊！！
