Hi Prithvi. An example of a JSON response is provided in this newly published article and pasted below:
http://code.google.com/apis/opensocial/articles/cloud.html {"resultsCollection":[ { "name" : "01495306580392390900", "photos" : [ { "url":"http://foo";, "tags":["Aruba", "snorkling", "fish"] }, { "url":"http://bar";, "tags":["snorkling", "shipwreck"] } ] }, { "name" : "14088281537290874435", "photos" : [ { "url":"http://baz";, "tags":["food", "pasta", "linguini"] }, { "url":"http://raz";, "tags":["food", "dessert", "apple pie"] } ] } ]} Notice that the result is a single array called resultsCollection. The array contains various objects, one per requested friend. The friend objects have the name/ID of the friend and an array of photo objects associated with that friend (the example is a photo sharing application). A callback would look like this: function callback(respItem) { var resultsCollection = respItem.data.resultsCollection; for (var i=0; i<resultsCollection.length; i++) { // Process each friend's data } } I hope this helps. Please let me know if you have any additional questions. - Jason On Jul 5, 1:29 am, Prithvi Raj <[EMAIL PROTECTED]> wrote: > Thank you very much for your reply Mr.Jason. > > Can you also write a callback function for the example you provided > above.
