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".
