// Lightbox
    $('a.lightbox').click(function () {
        $.getScript("js/lightbox.js", function () {
            alert('Load Complete');
            $("a.lightbox").lightbox({
                'type': 'iframe',
                'overlayOpacity': 0.6,
                'width': 940,
                'hideOnContentClick': false
            });
        });
    });

I want to load script on first request, but it doesn't seem to work, the page just redirects to the linked website, does not open iframe in lightbox.

Thanks for your help.
