Multiple NONAME buttons and WWW::Mechanize

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I'm having trouble getting buttons to fire on a web page that has several unamed buttons via Mechanize.

1. I tried mech->submit_form() which failed to click the button but correctly updated the form values. (As expected.)

2. Next I tried following the submit_form() by a click_button(number => 3) and when that failed I tried click_button(value => "Save'n Start". Both of these failed to work.

3. So then I tried individually setting the form values via form_number() and 3 field(name,val) follwed by the two click_button calls. Again, no luck and this time the form values were not updated either.

Any ideas?

#!/usr/bin/perl

use WWW::Mechanize; ## Automate Grabbing Webpages
use strict;

## What URL shall we retrieve?
my $url = "http://10.10.10.10/bdtconfig.shtml";
my $mech = WWW::Mechanize->new(autocheck => 1);
$mech->default_headers->authorization_basic("user", "pass");
$mech->get($url);
my $page = $mech->content;
$mech->dump_all(undef, 1);
#print $page;

my $resp2=$mech->submit_form(
          form_number => 1,
          fields      => { bdtminvolt => 49.0,
                           bdtmaxtime => 0.3,
                           rect_stby_volt => 45.0 ,},
);
print "Now clicking ...\n";
my $resp3=$mech->click_button(value => "Save'n Start");
#$mech->form_number(1);
#$mech->field('bdtminvolt',48.0);
#$mech->field('bdtmaxtime',0.2);
#$mech->field('rect_stby_volt',45.0);
#my $resp3=$mech->click_button(number => 1);
#print $resp3->content;

Here is the output, which include a dump_all().

You're setting fields that don't exist - rename 'bdtminvolt' to 'bminvolt' and 'bdtmaxtime' to 'bmaxtime' and see what happens.	[reply]

As you can see there is JAVASCRIPT code. Could that screw up the parsing? Should I use LWP module instead or do a one off hack?	[reply]
Re^3: Multiple NONAME buttons and WWW::Mechanize by dneedles (Sexton) on Feb 06, 2010 at 06:04 UTC
I see that Mechanize doesn't handle java script and the buttons invoke java script. I'll see if I can preprocess within PERL and hack around to invoke the button.	[reply]
