[Javascript] RegEx for validating a file name

[shawn.milo at gmail.com (Shawn Milo)]

Well, I'm assuming that the OP knew why he wanted it that way. He
specified alphanumeric and a three-digit extension, so that's what I
matched. I tend to be extremely annoyed when I ask a question on a
mailing list and the replies explain why it's a bad idea, rather than
how to do it.

For example, I found a post yesterday where someone had asked how to
mount a Samba share over the internet from their home machine. The
only reply was one saying that this was very unsecure and should never
be done. I think that this information is useful to the OP, but should
only be provided if the reply also contains some kind of answer to the
question. I think that people who leave those kind of replies are more
interested in appearing smarter than someone else than helping someone
else.

No offense to Paul and Hassan -- your comments were constructive to
the situation in this case. I guess I just felt like bitching about
the topic, and the opportunity arose in my 'home' mailing list.  Also,
I probably felt the need to explain why I provided a solution for what
might have been the wrong question -- to be helpful.
