Your problem is with setTimeOut . It looks like you're trying to call the ajax twice.

If you want to call the second ajax on success, there's no need to iterate through the array. Simply call another ajax on the first ajax success.

Get rid of $.each and do it like this:

$.ajax ({
  url: link1
  success: function (data){
    $.ajax ({
      url: link2
     });
  });
)};

If you're going to send multiple requests to multiple URLs: just send each by the same request , params ...

But if you want to handle responses after sending all requests, the first idea in my mind to solve this is Promise , I tried with native Promise and it worked , but if you prefer jQuery , I suggest you have a look on jQuery.when() , this one maybe what you're looking for ( check the deferred part).
