Q:

Facebook returning data as string, json data is expected

I am using FQL to fetch data from Facebook graph API.When i give a get request via jquery to Facebook, I get the response data in the call back function but,when I tried to process it,i found that the response is treated as a string(I am not able to iterate through it considering it as dictionary) but firebug log shows the following json data. 
console.log(response);

RESULT:
{
  "data": {
    "fql_search_result": [{
      "aid": "xxxxx",
    }, {
      "aid": "xxxxx",
    }, ]
  }
}

I got error saying response has no attribute data, when i did this
console.log(response.data)

Why is the data treated as string and not as dictionary? 

A:

Did you give the dataType as 'json' in the request that you made via jQuery? 
dataType:'json',

Alternatively you can try using the jQuery short hand function for AJAX GET Requests which has dataType as 'json' by default.  
jQuery.getJSON("https://graph.facebook.com/fql?q=SELECT+name+FROM+user+WHERE+uid+%3D+me+%28%29&access_token=<access_token>", function(data){
    console.log(data);
    console.log(data.data[0].name);
});
