Re: mech and javascript modifying form post action

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_stu ff',
$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);

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 . When the user
clicks, javascript alters the form before submission to be 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,
Neville

Thanks!! That is just what I was looking for. I used your 2nd =
implementation (large stone hammer with update_html ) as that seemed =
more intuitive to me.

I'd suggest to anyone wanting to work javascript code actions into mech =
to use this method. It worked like a charm.

my $form =3D $mech->form_number(2);
$form->action(URI->new_abs('somewhere_else.aspx?appended_stu ff',=20

$html =3D~
s{\Qaction=3D"start.aspx"}
{action=3D"somewhere_else.aspx?appended_stuff"};
$mech->update_html($html);
$mech->submit_button(form_number =3D> 2);
