Is there any way to get jQuery ajax upload progress?

Question

$.ajax({
  xhr: function()
  {
    var xhr = new window.XMLHttpRequest();
    //Upload progress
    xhr.upload.addEventListener("progress", function(evt){
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        //Do something with upload progress
        console.log(percentComplete);
      }
    }, false);
    //Download progress
    xhr.addEventListener("progress", function(evt){
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        //Do something with download progress
        console.log(percentComplete);
        }
      }, false);
    return xhr;
  },
  type: 'POST',
  url: "/",
  data: {},
  success: function(data){
    //Do something success-ish
  }
});

This does not work on jQuery 1.5+ because the xhr is replaced by the jqXHR (i.e. a high level version of the raw XHR.) Now the question is how to get it to work with jqXHR… Anyone know how to do it?

Try this

$.ajax({
    url: path,
    xhr: function () {
        var xhr = $.ajaxSettings.xhr();
        xhr.upload.onprogress = function (e) {
            if (e.lengthComputable) {
                console.log(e.loaded / e.total);
            }
        };
        return xhr;
    }
}).done(function (e) {

})
