jQuery-File-Upload not firing done callback in Internet Explorer (IE9)

Question

i checked some questions regarding the same issue, blueimp jquery file upload - "done", "complete" callbacks not working for IE 9 , but even after puttin

Answer 1

The most voted answer isn't the best solution and can throw errors. Actually, setting dataType isn't recommended for IE < 10, from this (awesome) article:

When the dataType option is set to text, json, html, or script, the iframe transport performs some processing of the response. Because it is operating on a DOM object obtained from the iframe it uses, however, and not the raw HTTP response data, there is the potential for some surprises to pop up.

Real solution:

The "thing" about not firing in IE < 10 isn't related with dataType, is just the lack of callback add that forces the file push in fileupload event.

$('#file_file').fileupload({
    add: function (e, data) {
        data.submit(); //this will 'force' the submit in IE < 10
    },
    done: function (e, data) {
        alert('Done');
    }
});
