HTML控制

你不能。
安全停止你知道有关客户端计算机文件系统的任何信息 - 它甚至可能没有！它可能是MAC，PC，平板电脑或支持互联网的冰箱 - 你不知道，不知道也不会知道。让你有完整的路径可以给你一些关于客户端的信息 - 特别是如果它是一个网络驱动器。
事实上，你可以得到它特定的条件，但它需要一个ActiveX控件，并不会在99.99％的情况下工作。
你不能用它来将文件恢复到原来的位置无论如何（因为你完全无法控制下载的存储位置，或者即使存储它们），所以在实践中它对你来说并没有多大用处。

You can''t.
Security stops you for knowing anything about the filing system of the client computer - it may not even have one! It could be a MAC, a PC, a Tablet or an internet enabled fridge - you don''t know, can''t know and won''t know. And letting you have the full path could give you some information about the client - particularly if it is a network drive for example.
In fact you can get it under particular conditions, but it requires an ActiveX control, and will not work in 99.99% of circumstances.
You can''t use it to restore the file to the original location anyway (as you have absolutely no control over where downloads are stored, or even if they are stored) so in practice it is not a lot of use to you anyway.
