Javascript code is a scripting language designed for use within a web page and/or on a web server. It is used to create special effects within a web page. In order to call your javascript code, you will need to link to the file. You can do so by placing a small javascript code within the HTML of your web page that looks something like this:

<SCRIPT language="Javascript" src="http://www.yoursite.com/yourfile.js">
