You can use several different
methods of placing javascript in you pages.
You can directly add a script
element inside the body of page.
1. For example, to add the
"last updated line" to your pages, In your page text, add the
following:
<p>blah, blah, blah,
blah, blah.</p>
<script
type="text/javascript" >
<!-- Hiding from old
browsers
document.write("Last
Updated:" +
document.lastModified);
document.close();
// -->
</script>
<p>yada, yada,
yada.</p>
(Note: the first comment,
"<--" hides the content of the script from browsers that don't
understand javascript. The "// -->" finishes the comment. The
"//" tells javascript that this is a comment so javascript doesn't
try to interpret the "-->". If your audience has much older
browsers, you should put this comments inside your javascript. If most of your
audience has newer browsers, the comments can be omitted. For brevity, in most
examples here the comments are not shown. )
The above code will look like
this on Javascript enabled browsers,
2. Javascript can be placed
inside the <head> element
Functions and global
variables typically reside inside the <head> element.
<head>
<title>Default Test
Page</title>
<script
language="JavaScript" type="text/javascript">
var myVar = "";
function
timer(){setTimeout('restart()',10);}
document.onload=timer();
</script>
</head>
Javascript can be referenced
from a separate file
Javascript may also a placed
in a separate file on the server and referenced from an HTML page. (Don't use
the shorthand ending "<script ... />). These are typically placed in
the <head> element.
<script type="text/javascript"
SRC="myStuff.js"></script>
