Enabling callback function encapsulation for JSON

[gallien-lbr]

I'm having a problem using the API with jQuery, because It is not possible to do cross-domain AJAX using the conventional XMLHTTPRequest. Would It be possible to encapsulate the returned JSON into a function call ?
So we could use an url such as :

http://api.mp2013.fr/near?from=2013-01-01&to=2013-01-15&lang=fr&offset=&limit=1&format=json&latitude=43.307192&longitude=5.372314&callback=foo

that returns:

foo(
{
//json
})

here is an article relative to this issue : http://fcargoet.evolix.net/2009/02/jsonp-avec-jquery/ (in french)

Best regards,

I have the same issue, is about some URLs work, some not. For the URLs only return json, how to encapsulate the jsonp callback function to the json result?
