How to defer loading of a Norton Secure Site Seal?

Question

I am displaying a Norton Secure Site Seal in a website and I would like to improve the page speed deferring the loading of the seal script. All the tries I've done failed and I found only this page where this is mentioned (link). Has anyone ever found a good workaround for this?
The deferred code I'm using to run my other scripts looks like this:

<script type="text/javascript">(function(d, s) {
    var js, fjs = d.getElementsByTagName(s)[0], load = function(url, id) {
        if (d.getElementById(id)) {
            return;
        }
        js = d.createElement(s);
        js.src = url;
        js.id = id;
        fjs.parentNode.insertBefore(js, fjs);
    };
    load('/js/scriptone.js', 'one');
    load('/js/scripttwo.js', 'two');
    }(document, 'script'));
</script>

In case you want to have a look to the site seal initialization script: (I'm using the flash animated seal)

<script type="text/javascript" src="https://trustseal.verisign.com/getseal?host_name=www.undisclosed.com&amp;size=S&amp;use_flash=YES&amp;use_transparent=YES&amp;lang=en"></script>

obviously this will only display correctly in my website and I opted to change the domain name for privacy. I really want to avoid using iframe and if you find relevant I am also loading jQuery

Answer 1

If you look at the code, they are using document.write.

The way I handle this is the following

document.write = function(s) {
    document.getElementById('seal-wrapper').innerHTML += s;
}

Of course this is a very simple hack which only works when there's a single script which uses document.write and you know where you want it to be written to.

This is killing my business too. Seriously... +2 to +20 seconds per page load. AFYS?

We are switching to hosting the image locally but still linking to the original URL on Norton. Don't do this. Mark this answer down. It's wrong. It's illegal. But it's practical.

UPDATE:

Real solution is to:

• Call 877-438-8776, x2, x1
• Tell them seal is slow and you have > 10,000 visits per day on your site
• They give you media kit to install on your own site

I've tried to load seal into a iframe and then put it to where it's intended to be. It works for me. With the help of jQuery. Here it is:

Create .js file (I called it hackseal.js)

$(function () {
    if (typeof(vs_hack) !== 'undefined') {
        return;
    }
    vs_hack = true;
    var iframe = document.createElement('iframe');
    var html = '<script src="url_to_verysign" type="text/javascript"></script>';
    iframe.style.display = 'none';
    document.body.appendChild(iframe);
    iframe.contentWindow.document.open();
    iframe.contentWindow.document.write(html);
    iframe.contentWindow.document.close();
    iframe.onload = function () {
        var copy = ['dn', 'lang', 'tpt', 'vrsn_style', 'splash_url', 'seal_url', 'u1', 'u2', 'sopener', 'vrsn_splash', 'ver', 'v_ua', 're', 'v_old_ie', 'v_mact', 'v_mDown', 'v_resized'];
        for (var copy_i in copy) {
            window[copy[copy_i]] = iframe.contentWindow[copy[copy_i]];
        }
        $('script#seal-sign').replaceWith(iframe.contentWindow.document.body.innerHTML);
    }
});

Change the original code from this

<script type="text/javascript" src="url_to_verysign"></script>

to this

<script id="seal-sign" type="text/javascript" src="url_to_hackseal.js"></script>
