推荐答案

prototype.js 代码很可能没问题，它可能是对不存在的元素的 setStyle() 调用.

The prototype.js code is most likely fine, it's probably a setStyle() call on an element that doesn't exist.

如果您使用 Internet Explorer 8，请按 F12 打开开发人员工具.切换到脚本"选项卡，然后找到堆栈跟踪.堆栈跟踪将向您显示进行违规 setStyle() 调用的位置.这可能已经给你一个提示wnat's wrong;如果没有，请返回该信息.

If you use Internet Explorer 8, press F12 to open the developer tools. Change to the "script" tab and then find the Stack Trace. The stack trace will show you the point where the offending setStyle() call was made. That might already give you a hint wnat's wrong; if it doesn't, come back with that info.

您可以对 Firefox 和 Firebug 执行相同的操作.

You can do the same with Firefox and Firebug.
