jQuery: Add 'maxlength' support to textarea fields. Validates cleanly in JSLint.

gistfile1.js

(function ($) {

    'use strict';


    $.textareaMaxlength = function () {

        // Allows the 'maxlength' attribute to be used with textarea fields to limit the
        // number of characters that can be entered.
        // e.g <textarea id="myfield" maxlength="250"></textarea>

        // jsFiddle: http://jsfiddle.net/davidwaterston/DdxCQ

        $(document).on('keyup input paste', 'textarea[maxlength]', function () {

            var maxlength = parseInt($(this).attr('maxlength'), 10),
                text = $(this).val(),
                textlength = text.length;

            if (textlength > maxlength) {
                $(this).val(text.substr(0, maxlength));
            }

        });

    };

}(jQuery));

Replaced 'bind' with on to allow delegation.
