It's impossible to prevent your javascript from being copied to some other site and being used from there. In fact, it's also trivial to spoof everything so as to make your service think that the actual customer is making the request.

If this is a problem, find a way to restructure your service such that the APIs are private - not for being called by your customers' customers. For an example, look at Google's OAuth flow. Perhaps this will work, perhaps not - you haven't told us much about what exactly it is you're trying to accomplish.
