I am trying to use the graph API to get just some basic info about a user no need for authorization by the user just the public details. I am trying to use jQuery and the .getJS
You have to use jsonP for cross domain issues:
jsonP
$.get(fburl, function(data){ console.log(data); alert(data.name); },'jsonp');
