Simple Char Counter For Inputs and Textareas

A simple jQuery plugin that attachs a character counter to your form input or textarea elements to limit the maximum length of user input.

Basic Usage:

1. Include jQuery and charactercounter.js

<script src=""></script>
<script src="jquery.character.counter.min.js"></script>

2. Markup. Set the maximum length via data-max-length attribute

<textarea cols="50" rows="20" id="tester" data-max-length="400"></textarea>

3.  You can style your inputs and textareas with class of "character_counter" and "invalid".  The plugin adds a paragraph element with class of "character_counter". The count is updated on the keyup event and if the input exceeds the maximum length specified a class of "invalid" is added to the paragraph element.
