Yes, but I said "Or, if the link must be created on the server-side, try
something like:" and then gave the unhiding example.
Meaning, removing the hiding would be an easy way if for some reason the OP
found it much easier to make the link on the server. I can think of a few
reasons why this might be the case. For example, under MediaWiki media
paths contain md5 hashes that are only easily knowable on the server side.
I suppose you could use PHP to write a literal string value of the hash into
the javascript, but I was just trying to keep things simple.
