Selenium: Trying to resize window from Perl: getting a mysterious JavaScript error

[HelenCr]

Dear esteemed PerlMonks

I am using the Perl Selenium package, WWW::Selenium.

Trying to resize the browser window, I am getting a mysterious JavaScript error: "Threw an exception: missing ; before statement".

Here is the code:

use strict;
 use warnings;
 use 5.014;
 use autodie; 
 use warnings qw< FATAL utf8 >;
 use Carp;
 use Carp::Always;
use WWW::Selenium;

my $url = q{http://www.google.com}; #for example
my $sel = WWW::Selenium->new( host => 'localhost',
   port => 4444,
   browser => '*firefox F:\WIN 7 programs\Web & Internet\Firefox 8 bit
+\firefox.exe',
   browser_url => $url,
   );
$sel->open( $url );
$sel->wait_for_page_to_load(10000);
my $res = $sel->window_maximize();    # So far, this works fine
$res = $sel->get_eval( q{ WebDriver driver = ((WebDriverBackedSelenium
+) selenium).getWrappedDriver();
   driver.manage().window().setSize(1040,768);} );
   # (Following this: http://stackoverflow.com/questions/1522252/, Eli
+ Colner's post)

The program then crashes here with: "Threw an exception: missing ; before statement"

If I drop the first JavaScript line and just leave in the 2nd line, namely:

$res = $sel->get_eval( q{driver.manage().window().setSize(1040,720);} );

It bumps with: "driver not defined".

Help will be appreciated - Thanks in advance

Helen
