Is there a way of extracting the Javascript code from the "normal" HTML code
(e.g. similar to CSS code which can be put into a separate file) ?
If you offer a solution: can I determine in your solution where and which part
of the code should be placed/inserted in the main HTML code?
Sometimes a Javascript functionality is split up to several parts and/or
it makes a big difference where the Javascript code should run/be called
(e.g.
- in the <HEAD>....</HEAD> or
- at the beginning just behind the <BODY> tag
- at the end just before the </BODY> tag.

Yes, you can do this.
Add a line in the head of your code such as the following;
<script language="JavaS cript" src="include/bfinclude.js"></script>
(this includes a javascript file which is located in the directory
'include')
Note that the above looks very similar to the existing markers for inline
javascript code; instead of having the routines listed, it uses the 'src'
parameter to locate a source file. The contents of the javascript file
should be just javascript, nothing else.
For example, the code below would be the entire content of the bfinclude.js
file (including the html comments)
<!--
function MM_reloadPage(i nit) { // Reloads the window if Nav4 resized
if (init==true) with (navigator) {if
((appName=="Net scape")&&(parse Int(appVersion) ==4)) {
document.MM_pgW =innerWidth; document.MM_pgH =innerHeight;
onresize=MM_rel oadPage; }}
else if (innerWidth!=do cument.MM_pgW || innerHeight!=do cument.MM_pgH)
history.go(0);
}
-->
HTH,

Fair comment, and good advice. Thanks.

Thanks, but I do very little with Javascript, so I'm not staying around! I
only dropped in to see where my response had disappeared to, as it didn't
show up in the newsgroup I had replied to; the OP had cross-posted, but I
didn't notice at the time - I normally remove cross-postings before
replying.

You certainly can, its called a .JS file - see http://www.javascript-fx.com/general...aljs/help.html or search the web
for more info.

A) They may be useful if the page is being processed by software other

Agreed that they may be useful in software other than a browser. But that still
doesn't change the content type of a script block.
B) They are HTML comments, since they are for use when the script tag is
not recognised.
http://tinyurl.com/27c6l
Leads to a discussion not long ago (Nov 9, 2003) about whether they are HTML
comments or part of the script block. To quote Jim Ley:
<quote> That's a javascript comment, not an HTML one, and it can cause no harm
(in XHTML things are different of course)
The string "<!--" begins an HTML comment.
The content model of SCRIPT is CDATA - you're not allowed comments
inside it, therefore that must be part of the script, and passed to
the script engine. Certainly it's not part of ECMAScript, but that is
not an HTML comment - they're not legal inside SCRIPT blocks (this is
the change with XHTML of course where the content model of script
changed to PCDATA which allows comments.)
It's either a javascript comment, or something that the javascript
engine accepts as if it was a comment - it's passed as is via the HTML
parser.
Jim.
</quote>
So, they are part of the script block, and not an HTML comment.

The point that Dr. Stockton made, and that I wish I had made to Jim
Ley then, is that whether it is part of the script block or an HTML
comment depends on 1) the version of HTML and 2) the browser.
The reason to put the <!-- there at all, is that *some* browsers treat
it as the start of an HTML comment. Other browsers treat it as part
of the script block (and actually break ECMAScript compliance to do it:
var x = 2;
if (1 <!-- x
) { alert("foul");}
is a valid syntactically correct ECMAScript program that should not
call the function "alert", but does in the browsers I checked - IE 6,
Opera 7 and Moz FB).
But the reason to write the <!-- at all, is to have it interpreted as
an HTML comment. So, at least partially, it *is* an HTML comment.

No, its part of a script block that is interpreted as an HTML comment not a
true HTML comment.
All of it is purely semantical though until you escape the HTML world.

To Netscape 1, it is an HTML comment, because that browser doesn't
know what a script block is. As a well behaved HTML client, it ignores
unknown tags and finds the HTML comment inside.
The reason to add the <!-- and //--> is to make Netscape 1 and
contemporary browsers treat it as an HTML comment. Later browsers
gracefully ignores <!-- and --> inside script blocks, since they are
not placed there for these, smarter, browsers. It is added for one
purpose only: To be used as an HTML comment.
All of it is purely semantical though until you escape the HTML world.
To where? :)
The problem might be that it is the difference between HTML syntax and
actual browser semantics.
