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).

This detects screen resolution using javascript and makes it available to php by way of cookies.

This code allows you to set the "opcity" style attribute on a element without affecting it's content.

Just call the function for a specific element or to all elements of a given classname after the document loads.

Examples and advanced usage here...

These are some prototype methods to handle class names in html elements. As you all should know, a html element can have more than one class name.

This is part of my dom handling toolkit. Check it out and use it at will.

A simple, yet powerful (what a cliché) way of resgistering javascript keyboard shortcuts. Register any kind of keyboard shortcuts, and if applicable, override the browser default action.

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.

Ok, so I was getting frustrated with the inability to hide data in javascript, as well as a number of other concerns with existing class structures (the requirement to use this.constructor in lieu of self, for example).

As a result, I've thrown together a nice little class constructor that accepts a class definition, as well as a class extender that allows you to build a new class from an existing one, with full access to all that private stuff.

Ok, so here's the deal. I've started to dally with Flash a bit, and I'm feeling all naked without my nifty Prototype functionality.

Most important to me are the bind() and curry() functions (though, others will rear their heads as my AS code gets more complex), Object.extend, and $A. They are para-ported here.
