Cannot retrieve event object from facebook?

Can anyone help me, im trying to get this information from facebook:

https://graph.facebook.com/139373546157232/

This is my ajax call, but im getting a 200 bad request in the chrome error console and the following error:

XMLHttpRequest cannot load https://graph.facebook.com/139373546157232/. Origin http://delete-cardif开发者_开发知识库f.co.uk is not allowed by Access-Control-Allow-Origin.

 $.ajax({
url : "https://graph.facebook.com/139373546157232/",
success : function(data) {
    //Checking what's returned  
    console.log(data);
},
 dataType : "json"
 });

My understanding was I didn't need authentication to get this information? How would I go about retrieving the object?

Thanks

You can't retrieve JSON from an external URL. You need to use JSONP. In jquery, if you include callback=? at the end of your URL then it will work. Try:

$.ajax({
url : "https://graph.facebook.com/139373546157232/?callback=?",
success : function(data) {
   //Checking what's returned  
   console.log(data);
},
dataType : "json"
});
