【问题描述】：
我在查找一个脚本中出现的错误时遇到了问题。我在 FireBug 中收到以下错误：
未捕获的异常：语法错误， 无法识别的表达式：)
问题是在我的 base.js 内部引起的，猜测 sortable 函数不想与我的 jQuery 版本一起使用。请看以下演示：
http://dev.evilmile.de/CommandCP/
base.js 的第 656 行：我使用了 inettuts 脚本，它基本上克隆了 iGoogles 界面。该脚本使我可以对小部件进行排序，隐藏/显示内容并更改每个小部件的颜色，还将所有内容保存在 cookie 中以记住位置和样式。最初那个 inettuts 脚本是在 jQuery 1.2.6 和 UI 1.6.2 上运行的，我在 jQuery 1.4.2 和 UI 1.8.1 上，有什么问题。除了可排序功能外，所有功能在该组合中都运行良好，我没有得到任何移动等。

如果有人能提供提示在哪里找到问题，那就太好了。我的知识已经走到了尽头
提前感谢您的宝贵时间。 问候，
