Re^3: In a Web Page forms are displayed as empty

Hi jesuashok,

I had a hunch that the pages in question are generated by JavaScript using 'document.write', so I /msg'd you to confirm this. I have seen some pages that use document.write to output html. Let us take for a basic example the following html page:

<html>
<head>
<title>Bad Example</title>
</head>
<body>
<script>
document.write('<H1>JavaScript made me do it!</H1>')
</script>
</body>
</html>
[download]

Now the following Perl code:

#!/usr/bin/perl

use strict;
use warnings;

use WWW::Mechanize;

my $mech = WWW::Mechanize->new;

$mech->get('http://yourserverhere/test.html');

print $mech->content( format => "text" );
[download]

Which outputs: "Bad Example". Why? Because "Please note that Mech does NOT support JavaScript. Please check the FAQ in WWW::Mechanize::FAQ for more.".

You can use Win32::IE::Mechanize or Mozilla::Mechanize or alike to control a browser which does know how to deal with JavaScript. This is another reason to always refer to the documentation.

Update: Excuse the lack of error checking in the Perl script above, I wanted to get this post to you ASAP and I have to attend a project meeting.

Hope this helps

Martin
