Re: [dancer-users] How do I call a script from a template?

1 May 2015


      Thanks. I get it now. For some reason my mind was clearly clouded with
only using Dancer the way I had been.

Hello
from you html code you can call a route, and this route can call a
perl script ,  not directly a perl script
see this example
My route:
use Dancer::Plugin::Ajax
ajax '/example/add' => sub {
my $parm1       = params->{'param1'  } // undef;
         my $param2     = params->{'param2'   } // undef;
         my $param3     = params->{'param3' } // undef;
....
my $cmd = "/usr/bin/sudo
/home/example.pl &";
                                  my $result = `$cmd`;
                                  warning $result;
$result=decode('UTF8',$result);
if ( $result ) {
return template
'prelevement/list' => {
show_warning    => "Erreur<h4>$result</h4>",
                                          };
} else {
return template
'prelevement/list' => {
show_success    => "Calcul <h4>please wait </h4>",
                                         };
                                  }
};
My js jquery code in my template ( use class="Example" )
$(".Example").click(function(e){
           var param1       = $(this).attr('param1');
           var param2       = $(this).attr('param2');
           var param3        = $(this).attr('param3');
           var DATA           = "param1="+param1.toString();
               DATA          += "¶m2="+param2.toString();
.....
.....
// fonction Ajax.
          if ( Statut != 'Ok' ) {
                        $.ajax({
                                url: "/example/add",
                                dataType: "JSON",
                                data: DATA,
                                success:function(data){
                                        // Ne changer la couleur du
bouton que pour info
                                        if (! BoutonCouleur ) {
$('#'+Name).removeClass('btn-default').addClass('btn-success');
$('#'+Name).html('Ok');
                                        }
                                },
                                error: function(data) {
                                $('#'+Name).html('Erreur');
$('#'+Name).removeClass('btn-default').addClass('btn-danger');
                                }
});
          }
});

In a template I invoke (successfully) from a Dancer2 path I have
some jquery
that works outside Dancer2:
Like Andrew pointed, you don't call anything from template, you use
template to generate HTML-page, which contains javascript and
client/browser makes separate request to get some content from server.
This content could come from other route or from other server,
whatever. So, instead of script data1.pl seems reasonable to have a
route in your Dancer app, which answers to those requests.
Client side (javascript in browser) does not know anything of your
serverside content generation, so templates do not matter here.
