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

(function () {

// padded with an extra leading zero, if necessary.
function pad(number) {
var r = String(number);

davidwaterston / Increment number part of string
Created April 20, 2014 10:22
Javascript: increment the number part of a text field e.g. take a text field containing "abc15" and increment it by 1 to return "abc16", "xyz99" will become "xyz100", etc. Really shouldn't be doing this but if you have to then this will do it. See it in action: http://jsfiddle.net/davidwaterston/a8yXH/
var myString = "abc99";
newString = myString.replace(/\d+$/, function(n) { return ++n });
