Real-world JavaScript: Scripting Checkboxes

What is a checkbox really used for, and how can you change it with a JavaScript? Is it even possible? It certainly is, and in this article you'll find out how to manipulate checkboxes in a form using the mysterious "type" property. Create a toggle switch and turn on and off mass checkboxes with a flick of the wrist! Amazing! Tom continues showing you how to make fully-functional forms, and shows how to make sure that they are Accessible under 508 and disability discrimination legislation - and it's all easier than you think!

This self-contained article will contain the first of many JavaScripts that will be part of a library of scripts you can keep free of charge for your own use.
