This is your normal response json object, my program must to return extra data of json,
I have found to echo my json by edit "ajax-multiplefiles-handler.php", and I can get the json of my need,
but I find the progress bar is not running, whether the three parameter FileGuid, FileSize and FileName must be included in json?
What topic may I know to edit my own json?
