Never mind. I found another way to do it. Sorry for bothering you.

I’m glad to hear you found a solution.  However, I suspect there *is* a bug in one of my
modules.  If it’s not too inconvenient, could you attach to this ticket the script at
<http://tsdr.uspto.gov/js/lib/jquery.multiselect.js>?  (I have limited web access.)  That may
be enough for me to track down the issue.  Thank you.

I'm trying to use WWW::Scripter with the Ajax plugin to scrape the

  information from a webpage. It is my understanding that the get
  method retrieves the HTML, executes the AJAX code, and makes the
  response available through the content method.

Here's my code:

#!/usr/bin/perl -w

use strict;
use WWW::Scripter;

###### Scripting declarations #############

my $w = new WWW::Scripter;
$w->use_plugin('Ajax');

####### Redirect output of curl to WHILE loop; reads USPTO web page

  line-by-line

my

$url='http://tsdr.uspto.gov/#caseNumber=85304498&caseType=SERIAL_NO&searchType=st
atusSearch';

$w->get($url);
print $w->content;

The resulting content will be parsed by Perl (this is test code —

  there are lots of these pages I'm trying to automatically parse).
  I've already written the Perl code to parse the page, and the site
  recently switched from server-side execution to an AJAX-based
  implementation. The AJAX code appears to automatically populate the
  page when the variables are set in the URL indicated above. That
  is, no form submission is required in a browser when the URL above
  is used.

This code returns the following error during the get method:

Error: Can't locate object method "style" via package

  "JE::Object::Proxy" at /Library/Perl/5.10.0/CSS/DOM.pm line 155.

TypeError: The object's 'widget' property (undefined) is not a

  function at http://tsdr.uspto.gov/js/lib/jquery.multiselect.js,
  line 647.

Then, the code prints the HTML as it appears before the AJAX code

  populates the appropriate <div> tag. It returns the content but
  not, as the WWW::Scripter documentation indicates, after it has
  been modified by scripts.

It is not a function of enabling fetch_images, because I tried that.

Is this a bug? Or am I missing a step required to evaluate the AJAX

  code on the page?

Thanks,
Nathan
