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.

Remove all children of Object.

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.

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.

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.
