I'm using rails, but doing all my Javascript unobtrusively using jQuery in `application.js`.

Unfortunately, this makes it quite difficult to reference URLs. For example, if I want to give a field autocomplete behavior, I have to hard-code the autocomplete URL in `application.js` since the rails `url_for` isn't available.

Is it possible to make `application.js` use erb? Am I thinking about this the wrong way?
