Textarea Max Size form question

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... <keanu reeves> What do you do...what DO you do? </keanu reeves> 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...

there is a thread in the last 30 days that discusses this, check the hof site...its there. http://www.houseoffusion.com/cf_lists/index.cfm/method=messages&threadid=317 24&forumid=4 tony 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... <keanu reeves> What do you do...what DO you do? </keanu reeves> Any scripts or dreamweaver behaviors anyone know of that can be plugged in quickly for an onblur() check?

Thanks tony!

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.

<script> function checkLength(field, len) {   if(field.value.length > len)   field.value = field.value.substr(0, len); } </script> <form> <textarea onKeyUp="checkLength(this, 10);"></textarea> <input onKeyUp="checkLength(this, 12);" /> </form> ----- Excess quoted text cut - see Original Post for more -----
