Recursive search through and object in JavaScript. As long as bitly really responds with some JSON to your request, responseText should contain the JSON code as text, so all you've got to do is to parse it with JSON. content_profile_test2"; var myInfo = getInfobyID(myID); function getInfobyID(myID){ var matchingObj = myArrOfObj.
