  "Message": "Success",
  "Code": "200",
  "Payload": [
    {
     "year": "2015",

Answer 1

Very simply. Payload is property of the object that you have provided, which can be accessed like this: json.Payload . So you should pass it as the first argument to $.each() method. Here you go:

$.each(json.Payload, function(idx, obj) {
     console.log(obj);
 });

You can also use

$.map(array,function(obj,index){
     console.log(obj)
});

for iterating through an array
