.fileupload({
    add: function (e, data) { 
        var attachmentValue = 3 * 1000 * 1024;
        var totalNoOfFiles = data.originalFiles.length;
        for (i = 0; i < data.originalFiles.length; i++) {
            if (data.originalFiles[i]['size'] > attachmentValue) {
                $attachmentsList.find('.uploading').remove();
                $attachmentMessage.append("
" + 'Uploaded bytes exceeded the file size' + "
");
                $attachmentMessage.show().fadeOut(10000, function () {
                    $attachmentMessage.html('');
                });
                data.originalFiles.splice(i, 1);
            }
        }
        if (data.files[0]) {
            $attachmentsList
           .prepend('
' + data.files[0].name + '
');
        }
        data.submit();                    
    }
