Access-Control-Allow-Origin error sending a jQuery Post to Google API’s

I solved the Access-Control-Allow-Origin error modifying the dataType parameter to dataType:’jsonp’ and adding a crossDomain:true

$.ajax({

    url: 'https://www.googleapis.com/moderator/v1/series?key='+key,
    data: myData,
    type: 'GET',
    crossDomain: true,
    dataType: 'jsonp',
    success: function() { alert("Success"); },
    error: function() { alert('Failed!'); },
    beforeSend: setHeader
});
