Synchronize Json data from server responce

I have two async responces from Ios server:

serviceResponce1 = function(response, request){
   result1 = Jquery.parseJson(request);
}

serviceResponce2 = function(response, request){
   result2 = Jquery.parseJson(request);
}

Than I need filter these two results:

filterArray = result1.filter(function(item){
   return result2.indexOf(item.Id) !== -1;
}

but they coming asynchronous and filter doesn't works. (when I hard code data, it works) How to synchronize them?

The easiest way to achieve that is to make the second request inside the handler of the first request and then handle the response:

request1(function(res1) { 
 request2(function(res2) { 
  filter(res1, res2); 
 }) 
});

The second way is to use deferred object, if you using jQuery (latest versions) then you can use:

$.when(request1, request2).done(filter)
