The contents of a simple form are sent to a Perl CGI in the server.
The Perl code is:
use CGI qw(:standard);
print "Content-type: text/html\n\n";
print "<html><head></head><body>Testing Thruput<br>";

print "<script language="JavaScript">";
print "</script>";

$value = param(myname);
print "$value<br>";
$value = param(addr);
print "$value<br>";
print "</body></html>";

If <script language="JavaScript"> and the matching </script> tag are
output to the browser, it will not process -- the browser hangs. If
these two lines are commented out, the browser handles the page
without a problem.

Question: Cannot a CGI output an HTML page that includes JavaScript?

I'm either missing something basic, or making a dumb mistake.

You have a quoting problem.

Try:

print "<script language='JavaScript'>";
print "</script>";

or:

print "<script language=\"JavaScript\">";
print "</script>";

Quote marks!

And, since 1996, the language attribute has been deprecated and the type
attribute required.

print qq(<script type="text/javascript">);

or

print "<script type=\"text/javascript\">";

For future reference, that would have made a much better
subject line than "Show Stopper".

Or
print "<\/script>";

No need for that, since Perl doesn't find anything magical about "</".

That's only necessary if the code that's doing the writing is within
an XHTML page.

Thanks to all of you for pointing out this basic error on my part. I
discovered it after I'd posted the message, and feel like a beginner
(which I am)!

And roger on a better subject line for my original message. I'll have
to think more about the subject, and not my feelings of the moment.

Thanks, all
Pat

I just thought that this concept should not be buried in a thread, so I made
it the subject line. Not only newbies, either!
