Textarea Max Size form question

You want to use onKeyUp, not onKeyPress, because onKeyPress fires before the
character is actually typed. In other words, you trim the string, recount
the chars, whatever, and then the character is appended, throwing everything
off immediately.

Yeah, the script I dug up was basically the same thing...I kept thinking
that I had to submit the form to test that, and completely forgot about the
"onkeyup() and onkeypress() events..
Thanks tony!

<form>
<textarea onKeyUp="checkLength(this, 10);"></textarea>

Okay, so you've got a textarea...you want to make sure it's not more than
1024 characters, but you wanna do a clientside check on it...

What do you do...what DO you do?

Any scripts or dreamweaver behaviors anyone know of that can be plugged in
quickly for an onblur() check? Is there a CFINPUT solution to this perhaps?
I'm not using CFINPUT on any of the other form elements though...
