Opening the potplayer program failed

mapkey('P', "#7 open PotPlayer", function () { var objShell = new ActiveXObject("shell.application");
    objShell.ShellExecute("PotPlayer.exe", "", "", "open", 1);
});

I have also tried to run some programs (like notepad.. vim.. emacs) of the operating system directly using JavaScript, but it did not work. It seems not work properly on current javascript spec.
