What a javascript looks like ?

	Java Script

This is what a tipical Java Script looks like. This script is the one used for a sub menu system in the Javascript example.

<script language="JavaScript1.2">

            write(".child {position:absolute; visibility:visible}");
            write(".regular {position:absolute; visibility:visible}")
        }
        else {
            write(".child {display:none}")
