WWW::Mechanize and JS onClick attributes

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

Using WWW::Mechanize, how would I trip the onChange attribute in an <select> input? The relevant HTML is below.

<form name="someForm" id="someForm" method="POST">
  <select name="foo" onChange="someForm.submit()">
    <option value="1">First Option</option>
    <option value="2" SELECTED>First Option</option>
  </select>

WWW::Mechanize does not have any DOM or Javascript facilities, so you have no other choice but to look at the Javascript yourself and emulate what the Javascript does in Perl. If you're adventurous, you could look at what the CPAN has to offer on the topic, and use one of these solutions as basis. But you will still have to implement the browser DOM, which is quite some task to do properly. `perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ; # The $d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider ($c = $d->accept())->get_request(); $c->send_response( new #in the HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' # web` [download]	[reply] [d/l]

If I knew that the form had an action associated with it (which is not evident in the snippet you provided), I'd tell you to just have WWW::Mechanize set the value of foo to that of one of the two possible values and then submit the form.	[reply]

If I knew that the form had an action associated with it (which is not evident in the snippet you provided)... OT, but FWIW: if an HTML form tag does not include an action attribute, it defaults to being the same as the URL where the form was found.	[reply]
