This won't work in the newest browsers - restrictions on mixing local
and web content are generally getting stricter and stricter. You may
be able to configure Mozilla to be less strict but AFAIK Opera doesn't
permit it at all.

I don't see any strong reason for blocking JS access to the value
attribute though.
