Adding JavaScript to your Pages
This is very easy to do. Usually the applets, or scripts, that you'll find
include the code you'll need and also show you where to put it. Probably 7
times out of 100 the code is going to go between the
<head> </head> tags. Others are placed in the pages
themselves where they will appear. We'll use the old
TickerTape applet as an example.
1. Open up your HTML editor with the page that you want to add the script to. If you wrote a normal page, it should look a little like:
<html>
<head><title>Your Page Title</title>
</head>
<body>
</body>
</html>
2.Now, we want to add the code in-between the two <head> tags. So after the < title></title> tags, copy in the code from the script like so:
<html>
<head><title>Your Page Title</title>
<SCRIPT LANGUAGE="JavaScript">

3. Now save your file with the code in place.
4. Open up your favorite Java enabled browser (Netscape 2.0+ and
Microsoft Internet Explorer 3.0+) and view the page. You should see some
text floating down at the bottom saying
"one two three".
