使用JavaScript打开外壳

Question

是否有可靠的跨浏览器方式使用javascript（例如explorer.exe）打开外壳？

Answer 1

这是不可能的，因为这将是（漏洞）安全风险。

Answer 2

No, that is not possible for security reasons. Accessing client machine is the problme here !

Answer 3

If you have access to the client machine, and the client machines are all Windows XP or later, there actually is a way by defining a custom protocol as described in this SO question (Mozillazone article here ).

That way, you can create links like my_custom_protocol://helloworld.txt that cause an explorer window to be opened in Windows.

This potentially opens a (however remote) security hole, as connecting a custom protocol to explorer.exe could be used to send arbitrary parameters to that executable. Make sure you are aware of the security implications; depending on your situation, it might work for you, though.
