my $jS = JavaScript::SpiderMonkey->new();

$jS->init();


# create a new object, and set a method
my $document = $jS->object_by_path("document");

$jS->function_set("write", \&Write , $document);
$jS->function_set("writeln", \&WriteLn , $document);
$jS->property_by_path("document.location.href");


# Execute some code
my $rc = $jS->eval(q[

    document.location.href = append("http://", "www.perlmonks.org");

    document.write("URL is ", document.location.href);
    document.writeln("\nURL is ", document.location.href);

    function append(first, second) {
         return first + second;
    }

# Get the value of a property set in JS
my $url = $jS->property_get("document.location.href");
print "the $url is\n";
