                var ajax = new XMLHttpRequest();
                ajax.upload.addEventListener("progress", progressHandler, false);

            }

I can see </form> in your HTML but I can not find <form> tag. — Alp

Even with that line of code it only listens for the progress of one upload.

    function uploadFile(event){
  var file=event.target.files[0];
  //the same code as you wrote
}
