Try to use protocol relative links.

Your link is http://example.com/script.js, use:

In this way, you can leave the scheme free (do not indicate the protocol in the links) and trust that the browser uses the protocol of the embedded Web page. If your users visit the HTTP version of your Web page, the script will be loaded over http:// and if your users visit the HTTPS version of your Web site, the script will be loaded over https://.
