No, I don't want to write out a js function, just call one that's already there.
But that's ok. I'll just use a different implementation. I thought of it as a
solution and tried to determine how practical it was, which it wasn't. Shame
though, it's nice, easy gui to put up an alert.

That's correct.

It sounds to me like you want to have JavaScript form validation for
user-friendliness and convenience, and server-side form validation for
security and robustness.

return true;
} // end of new_fnc.....

that's not exactly what I meant. I meant to call the js function from cf, but
others have told me that this isn't doable or practicle. Really I just
wanted the js alerts.
Still, duplicating the cf function in js is almost a drop'n'play. Since it's
written in an ecma like script, all I really need to do is to change the EQ to
== (and such) and adjust the names of any api calls - createDateTime() becomes
Date().
thanks for answering Pascal, Dave and everyone.

Daniel,
You will need to duplicate the functionality. CFML functions only execute
on the server - building the page. JavaScript functions run in the browser
once the page is built and sent to the client.
Now depending upon your needs you can use CFML to build your JS function...

I have a cold fusion function that is used by other CF functions.
I've found that a JS function now needs it. Should I just duplicate
it for JS or can it use the CF function? I'd hate to dup it cause
it's the only place where a js function needs it.
thanks.

ah that makes total sense, said that way : )
And can I guess that the server-side CF, won't call a client-side JS function? I
guess I can validate this form in CF, but I'd still like to have the JS alerts
rather than go to another page, just to say "hey fill in the header,
guy!".

Client-side JavaScript run within a browser cannot directly invoke a
function written in CF.
