As stated in https://stackoverflow.com/a/3694435/460368, you could do :

if(xhr.upload)
     xhr.upload.onprogress=upload.updateProgress;

and

updateProgress: function updateProgress(evt) 
{
   if (evt.lengthComputable) {
       var progress = Math.ceil(((upload.loaded + evt.loaded) / upload.total) * 100);
       $("#dvProgressPrcent").html(progress + "%");
       $get('dvProgress').style.width = progress + '%';
   }
}
