How to chain ajax requests?

by

You could have a single function which is passed an integer to state what step the request is in, then use a switch statement to figure out what request needs to be make next:

function ajaxQueue(step) {
  switch(step) {
    case 0: $.ajax({
              type: "GET",
              url: "/some/service",
              complete: function() { ajaxQueue(1); } 
    }); break;
    case 1: $.ajax({
              type: "GET",
              url: "/some/service",
              complete: function() { ajaxQueue(2); }
            }); break;
    case 2: $.ajax({
              type: "GET",
              url: "/some/service",
              complete: function() { alert('Done!'); }
            }); break;
  }
}

ajaxQueue(0);

Hope that helps!
