Dropzone.js上传前重命名文件

Question

我正在尝试重命名dropzone上的文件名，但每次向文件名添加任何内容时，插件都会停止工作。

var temp = '/file-upload';
    var temp1 = '/file-delete';

    Dropzone.autoDiscover = false;
    var myDropzone = new Dropzone("div#gary-dropzone", {
        url: temp,
        addRemoveLinks: true,
        acceptedFiles: ".png,.jpg,.tif,.pdf",
        accept: function(file, done) {
            var selected_filenames = $.map(myDropzone.files, function(selected_file) {
                return (selected_file.name.replace(/\.[^.]+$/, ''));
            });
            // var filename = file.name.replace(/\.[^.]+$/, '')
            var filename = file.name.replace(/\.[^.]+$/, '') 
            actuallyDelete = "YES"
            if ($.inArray(filename, selected_filenames) != selected_filenames.length - 1) {
                var error_msg = "Error! The File is already in Queue";
                done(error_msg);
                actuallyDelete = "NO"
                myDropzone.removeFile(file);
            } else {
                done();
            }
        },
        removedfile: function(file) {
            var name = file.name;
            $.ajax({
                type: 'POST',
                url: temp1,
                data: {
                    id: name,
                    remove: actuallyDelete,
                },
                dataType: 'html'
            });
            var _ref;
            return (_ref = file.previewElement) != null ? _ref.parentNode.removeChild(file.previewElement) : void 0;
        }
    });

我最初的想法是传递名称以外的属性，但我无法弄清楚如何这样做。任何有关如何传递其他属性或名称更改的帮助都将受到强烈赞赏
