perl & javascript

Java Script is browser reliant. You can embed it into a Perl script, however it has to print to your browser before it can execute.

Thanks for your reply, but excuse me for appearing dumb (I'm completeley new to this - both perl & javascript), what do you mean by "printing before executing"?

Can you show me an example?

Not sure what the best example would be, but let’s say you’ve got a Perl script that prints a form box with dynamic content printed inside (for example the price of a product or what ever) you’ve also got a Java Script running in the PRINTED html that requires that only numbers can be entered into the text box.

Perl is server reliant and Java Script is client reliant. Which means Perl must be run from a server with Perl installed and Java Script must be run from a client (browser) with Java Script capabilities. You can mix the two together to their limitations (i.e. the Java Script HAS to be on the HTML page before it can run).

here is another, very simple sample for using javascript inside your perl script:

code:

#!/usr/bin/perl
$var = <<"EOF";
<script language="javascript">
alert("WELCOME MY FRIEND");
</script>
EOF

print "Content-type:text/html\n\n";
print $var;
[/code]
$var will contain all of the javascript.  After you print out the http header, you just need to print the $var, and it will execute the javascript command.

You can see it in use at http://www.wiredstart.com/cgi-bin/alert.pl 

Hope that helps a little
