Author: !i! Army !i!

Difficulty: Advanced

Details:


<!-- THREE STEPS TO INSTALL AGE CALCULATOR:

1. Copy the coding into the HEAD of your HTML document
2. Add the onLoad event handler into the BODY tag
3. Put the last coding into the BODY of your HTML document -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document -->

It has no direct purpose... it is a script, just so you can learn from it . When I want to learn something, about a scripting-language, I take all kind of scripts, because they all have a little different way of working. And by examinating them all, you can learn the language more complete .
