Question

How to retrieve data from the profile using JavaScript from Facebook in the database?

Is it possible to retrieve data using only JavaScript? Perhaps using jQuery?

Answer 1

Yes, you can get all information available to the Graph API via the Facebook Javascript SDK. See http://developers.facebook.com/docs/reference/javascript/

FB.api('/me', function(response) {
  alert('Your name is ' + response.name);
});
FB.api(
  {
    method: 'fql.query',
    query: 'SELECT name FROM user WHERE uid=me()'
  },
  function(response) {
    alert('Your name is ' + response[0].name);
  }
);
