Does jsonp depend on server support, in order to return a correct response?

I got this request, and what I get back is js error.

$.getJSON('myURL?q=keyword&callback=?', function(data){console.log(data)});

Does jsonp depends on some server implementations?

SOLVED!!!

This question is different from others cause no other answers speak about the proxy solution.

Answer 1

The server doesn’t return JSONP, it returns JSON. A JSONP result is a JSON result wrapped in a function call.

Example:

callback873659823745({"destino":"http://...", ... })

If you can’t make the server return JSONP, you would need a proxy server that requests the service and returns the JSON result wrapped as a JSONP result.

As it happens, I set up such a proxy a while ago, at jsonp.guffa.com, that you could use if you don’t have the ability to set up one yourself.
