Answer 1

$.getJSON("//ajax.googleapis.com/ajax/services/feed/load?v=1.0&callback=?", {
    num: 10,
    q: url
}).done(function (data) {
    console.log(data);
});

Notes:

• You're overdoing it. Don't try to specify information on the client side that the server actually has to supply (content type, allow origin headers, data type).
• You don't want XML, you want JSON.
• The name for cross-origin JSON requests is JSONP.
• jQuery implements that for you if you use the getJSON() API method . You don't have to do anything besides adding "callback=?" to the URL.
• Use jQuery Deferred callbacks ( then , done , fail and always ). They allow your code to become a lot more flexible.
• Have a look at the documentation, too. https://developers.google.com/feed/v1/jsondevguide

Answer 2

You basically can't implement a web client RSS reader because you can't be sure that content providers will set the correct CORS header for their feed(s) ; My advice would be to not waste your time reading through endless CORS/JSONP lectures (and trying misleading code) but implement a server solution (like, say Pétrolette ) and move on.
