Description: This useful form validation script lets you add a custom "maxlength" attribute to INPUT type="text" and TEXTAREA elements, so users are prevented from entering more characters into these fields than the designated number. Inspired by Twitter's input box, it can optionally show the number of characters remaining for a field as the user types while displaying this info in different colors depending on how close the user is to the limit.

Example :

Enter your hobbies (<50 characters)



Enter your postal code (<6 characters)
