<body onload="alert( 'This page has finished loading.' );">
<a onclick="alert( 'You clicked me!' );">

These files, just like externally linked css files, can be referenced in the following ways:
- Absolute reference: "http://ipirates.net/js/jsfile.js"

- Absolute reference to an external server: "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"
