Thanks for the input Rick,
Regarding the JS, it’s there only to give you additional statistical info about your players (like what search engine they came from, what keywords, screen resolution, etc).
If you don’t want to use the JS link, you don’t need to, just use the raw HTML part of the link.
You can also use the old links you already have, and it will still track fine, but the new links will be better for you in the long run I believe.
