No, because if it does not take a callback, then it is not Asynchronous, and subsequently it is no longer AJAX (Asynchronous Javascript And XML). And whereas it is common practice to replace the X with JSON or text, the Asynchronous part is pretty important.

You can make a Synchronous request, but it has its own issues... particularly that sometimes the web page and interface appear to freeze until the request returns.

Yes you can but it is a very bad practice. The javascript engine is single threaded and you risk locking the UI.

That would be a synchronous request, and JQuery does have this feature: http://api.jquery.com/jQuery.ajax/ Don't know if it's truly synchronous as I've not tried it that way. Look at the async setting in this documentation, set it to false.
