When did you add the JS? If you added it to MediaWiki:Common.js, as in the original reply, it will take some time for it to go through the review process. To avoid that, you can use MediaWiki:ImportJS instead. This allows to import of JS specifically from the dev wiki and, from my understanding, bypasses the review process.
