Hallo,

ist es möglich, dieses Skript so anzupassen, dass der Print-Button nicht mitgedruckt wird?

Code (perl): (dl )

#!/usr/local/bin/perl
use warnings;
use 5.012;
use utf8;
use CGI;

my $javascript = <<END;
function printpage()
{
        window.print()
}
END

my $cgi = CGI->new();

print $cgi->header( -charset => 'UTF-8' );
print $cgi->start_html(
        -script => { 
                -type => "text/javascript",
                -code => $javascript
        }
);
print $cgi->p( 'Hello World' );
print $cgi->start_form();
print $cgi->button( -name => "button_1", -value => "Print", -onClick => "printpage()" );
print $cgi->end_form();
print $cgi->end_html;

Das lässt sich leicht durch eine medientypspezifische Stilangabe lösen, zum Beispiel so:

Code (perl): (dl )

use 5.012;
use warnings;
use utf8;
use CGI;

my $javascript = <<'END';
function printpage() {
    window.print()
}
END
    
my $css = <<'END';
@media print {
    .hideme { display: none; }
}
END

my $cgi = CGI->new();

print $cgi->header( -charset => 'UTF-8' );
print $cgi->start_html(
    -style => {
        -type => 'text/css',
        -code => $css
    },
    -script => { 
        -type => 'text/javascript',
        -code => $javascript
    });

print $cgi->p( 'Hello World' );
print $cgi->start_form();
print $cgi->button( -name => 'button_1', -value => 'Print', -onClick => 'printpage()', -class => 'hideme' );
print $cgi->end_form();
print $cgi->end_html();

When C++ is your hammer, every problem looks like your thumb.
