You can't do a cross-domain POST. JSON or JSONP don't add this capability.
You just can't do it.
You can do a cross-domain GET, of course, and use query parameters to pass
data to your server.
So, you can use $.getJSON with query parameters in the URL and the callback=
option for JSONP, and have your server return a JSONP payload with the
results of your request.
$.getJSON(
'http://example.com/feedback?callback=?&feedback=' +
encodeURIComponent(feedback),
function( response ) {
...
}
);
