是否可以通过WWW :: Mechanize :: Firefox单击Javascript弹出窗口？

Question

I'll try to make myself as clear as possible. I want to download automatically a file. What I've done so far:

use WWW::Mechanize::Firefox;
use Crypt::SSLeay;
$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME}=0;
$url = $url.@ARGV[0]; 
my $mech = WWW::Mechanize::Firefox->new;
$mech->get( $url );
$mech->form_name('sysinfo');
$mech->click_button( name => 'download' );

When I click that button a window pops up, because of an onclick() js event. It asks what I want to do with the file, so I need to click the Save button. The thing is I can't get the window to do it. I can't use get because the only URL I know is the one that pops the new window up. I've couldn't find something similar. So is it possible to do what I want? or is there other way? I'd appreciate any help, thank you.

What is function on onclick()? Maybe you can try paste this in url bar javascript:function_on_onclick(param1, param2);

If it will be works, try $mech->get('javascript:function_on_onclick(param1, param2);');
