The method you're currently using is effective, though could be improved upon.
Imho, a better option might be to use js to add the link to the page.
Those with js get (access to) the additional info, whilst those without aren't offered a link which is of no use to them.
Alternatively, you could add some text telling users that js is required for certain info and then use js to turn that text into a link to that extra info.
Non-js users get the message, whilst js users get the link to the info.
