Re: mech and javascript modifying form post action

[Eamon Daly]

Each form is represented as an HTML::Form object, so you
could manipulate the form directly using those methods:

  my $form = $mech->form_number(2);
  $form->action(URI->new_abs('somewhere_else.aspx?appended_stuff', 
$mech->uri));
  $mech->submit_button(form_number => 2);

The action method requires a full URI, so that's what the
"URI->new_abs" part provides.

Otherwise, you could apply the large stone hammer approach of
rewriting the HTML yourself using the update_html method:

  my $html = $mech->content;
  $html =~
    s{\Qaction="start.aspx"}
     {action="somewhere_else.aspx?appended_stuff"};
  $mech->update_html($html);
  $mech->submit_button(form_number => 2);

Subject: mech and javascript modifying form post action


I am using mech to fill out a form. The problem is javascript is used to
alter the form before it is submitted. That is the html of the form
initially has <form method=post action=start.aspx>. When the user
clicks, javascript alters the form before submission to be <form
method=post action=somewhere_else.aspx?appended_stuff>. Since mech does
not understand javascript I cant simply click() or submit().

So, how do I fill out the form in mech and then change the target before
I use click() or submit? I can use standard perl to get somewhere_else
and appended_stuff, so that's not the problem. The problem is that I
don't know how to change mechs understanding of the form before
submission.

Any ideas?


Thanks,
