Prototype's Form.Methods library has a nice piece of code called 'serialize', which, if passed with the optional 'hash' parameter set to true, will convert an HTML form into a Javascript Object.

I was dismayed, however, to find that there was no way to reverse it; just as simply load a form using a Javascrip object.

So, here's one. enjoy.

Similar to Perl's CGI::escapeHTML(), though (because we can!) this adds it as a method to all String objects.

It works with Array types. The example is a simple list of numbers, but the array could contain anything; lists of strings, functions, DOM nodes, whatever. Unfortunately, a lot of things that seem like arrays in the DOM aren't really, so you can't shuffle the images on a page with just document.images.shuffle() all by itself.

I had searched high and low for a way to generate a palette of web-safe colors. Despite Google's best efforts, what I had found was lacking for my needs. So, I decided to write a library that would generate all 216 web safe colors, and then allow me to manipulate those colors in any way that I chose.

If anybody is curious as to why I would want to do something so... simple, it is because I needed a very light-weight color picker, and didn't want to mess with any fancy options.

Set a word or phrase in an input field, clear it onfocus

A simple demo of the google maps API

This script performs reliable, cross-browser input autofocus that often can be used simply by dropping it in, with no modifications to the form or HTML body. It refuses to switch focus if it detects that the user has interacted with the form (avoiding a major source of annoyance with autofocus scripts) and correctly handles Firefox tabs opened "in the background", which most autofocus scripts fail on. Official home is on the Lost Souls MUD Grimoire.

A simple, flexible formula for generating diminishing returns out of input numbers. Full explanation and home, with sample calculators and versions of the code in other languages, on the Lost Souls MUD Grimoire.

A wrapper on top of createElement for getting around IE problems with manipulating the name attribute. Unlike most solutions for this, it tests for which method to use once when the page loads rather than every time an element is created. By Chaos of Lost Souls MUD (a text-based fantasy RPG).
