jQuery-File-Upload done callback

Question

I'm trying to use blueimp's file upload, and -like a lot of people- I can't figure why the done callback doesn't work!

The file upload works well (I use the php upload handler) even if the fail callback send a fail issue. I've read a lot of topics about the json problems, but no answer fit my problem.

Here's my javascript code :

$(function () {
'use strict';
var url = 'server/php/';
$('#fileupload').fileupload({
    url: url,
    dataType: 'json',
    done: function (e, data) {
        $.each(data.result.files, function (index, file) {
            $('<p/>').text(file.name).appendTo('#files');
        });
    },
    fail: function (data) {
        alert("Fail!");
    },
    progressall: function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('#progress .progress-bar').css(
            'width',
            progress + '%'
        );
    }
}).prop('disabled', !$.support.fileInput)
    .parent().addClass($.support.fileInput ? undefined : 'disabled');
});

Do you have a solution or something to test to find some errors?

EDIT1: the success callback works only when I use dataType: 'text'

EDIT2: Here's is the response when the complete callback is triggered:

Answer 1

Remove the line "dataType: 'json'," and change "data.result.files" by "data.files" in the "done" callback and it works !

dataType: 'json',
        done: function (e, data) {
            $.each(data.files, function (index, file) {
                $('<p/>').text(file.name).appendTo('#files');
            });
        },

Answer 2

try moving the done to the end of the call

$.ajax({url: '/'}).done(function(data) {});

for your code it would be something like:

$('#fileupload').fileupload({
    url: url,
    dataType: 'json',
    success: function (data) {
        alert("Success!");
    },
    progressall: function (e, data) {
        var progress = parseInt(data.loaded / data.total * 100, 10);
        $('#progress .progress-bar').css(
            'width',
            progress + '%'
        );
    }
})
.done(function (e, data) {
        $.each(data.result.files, function (index, file) {
            $('<p/>').text(file.name).appendTo('#files');
        });
    )
.prop('disabled', !$.support.fileInput)
    .parent().addClass($.support.fileInput ? undefined : 'disabled');
});
