ajax without a callback

Question

Does any javascript framework has a function, which:

• makes AJAX request

• returns the response

  ( it does not take a callback function as an argument )

I basically want to do the AJAX request the same way I do SQL querys in C, python or whatever.

Answer 1

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

Answer 2

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.
