推荐答案

这个问题似乎是由Windows XP中修复但在我的Windows中显然没有修补的旧错误引起的7.从 http://support.microsoft.com/kb/929863 ：

The problem seems to be caused by an old bug that was fixed in Windows XP but is apparently unpatched in my Windows 7. From http://support.microsoft.com/kb/929863:

出现此问题是由于 ExecCommand 功能的限制。当您运行使用 ExecCommand 功能和 SaveAs 命令的脚本时，脚本只能保存文本文件类型的文件。

This problem occurs because of a limitation in the ExecCommand function. When you run the script that uses the ExecCommand function together with the SaveAs command, the script can only save a file that is the text file type.

果然，将文件扩展名更改为.txt并在IE8中神奇地观察它。

Sure enough, change the file extension to ".txt" and watch it magically work in IE8.

我想到的唯一解决方法是使用服务器端语言创建CSV文件，然后将其作为下载服务（使用 Content-disposition：attachment 标题）。

The only workaround that comes to mind is to have a server-side language create the CSV file, and serve it up as a download (using the Content-disposition: attachment header).
