如果你在线或本地测试，如果你有参数 allowscriptaccess="true" 就像 dome 说的那样，它应该可以工作.如果您使用 file://协议进行测试，您需要在 Flash Player 安全选项中允许您的驱动器.

if you test online or localhost, it should work if you had the param allowscriptaccess="true" like dome said. If you are testing with file:// protocol you need to allow your drive in the flash player security options.
