I don\'t use the UI part, only basic one.

When I do the following, I\'m having an issue in

Answer 1

I ran into this same issue. IE 9 would not trigger the done callback, but would trigger the always callback. The tricky part was extracting the JSON response object from the arguments. (Despite what the documentation claimed, I did not find that I needed to include jquery.iframe-transport.js.)

My implementation of the always callback looked something like this:

always: function(e, data) {
  var result;
  if (data.textStatus == 'parsererror') {  // IE9 fails on upload's JSON response
    result = JSON.parse(data.jqXHR.responseText);
  } else if (data.textStatus == 'success') {
    result = data.result;
  }

  if (result) {
    // ...perform custom handling...
  }
}

I believe issue can be in server response, you can make sure that server always send correct heading by using following code:

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . "GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
header("Content-type: text/x-json");
echo json_encode($array);
exit(0);
