HOW TO handle a API's JSONP response that uses a static or fixed or named callback function


Script and JSONP requests are not subject to the same origin policy restrictions. Most APIs that return JSONP data will generate a dynamic callback function name and they typically have a parameter like jsoncallback=?.

However some API's like flickr, Facebook require that you use the callback function name that they specify.

Here are a couple of ways that you can tackle that scenario -

window.fixed_callback = function(data){
  alert(data.title);
};

$(function() {
  $.getScript("http://api.flickr.com/services/feeds/photos_public.gne?tags=cats&tagmode=any&format=json&jsoncallback=fixed_callback", function(data) {
  alert('done'); } );
});
