RE: Formatting Numbers using JavaScript

Well I'll be! That looks just like one I wrote with my
own hands and offered on the list some months ago. I'm
flattered.  Then someone else -- my apologies, I
forget your name -- proposed one that was more compact
and elegant. Wanna show it to us again? Every so often
we go through this -- how to format a number as
currency in Javascript. HWG oughta have a Javascript
FAQ or something.

Notice how much easier it is with Perl (-: Yeah I
know, Javascript does it on the client side and it's
mighty fast, but people can disable javascript in
their browsers whereas they can hardly disable Perl on
your server.
