External JS Files

Question: Can I include JavaScript code from external JS files, rather than embedding all my scripts within HTML pages?

Answer: Yes. To do so, create a new file with the extension .js, for example, myscript.js. Put your JavaScript code in this file; do not include opening and closing SCRIPT tags in the .js file!

To embed myscript.js into your Web page, use these tags in your HTML file:

<SCRIPT LANGUAGE="JavaScript" SRC="myscript.js">
</SCRIPT>

In practice, you might find it convenient to create .js files containing JavaScript functions that you reuse on many different HTML pages. Please note, however, that some old browsers (e.g. Navigator 2.x and Explorer 3.x) cannot load external JavaScript files!
