[jQuery] pass multiple form fields to the $.ajaxFileUpload fileElementId

[jQuery] pass multiple form fields to the $.ajaxFileUpload fileElementId

Hi, I am trying to pass multiple form fields to the ajax_fileUpload.cfm
page with no success.  Is it possible to send a list of form ID's as I
am trying below?
$.ajaxFileUpload
        (
            {
                url:'ajax_fileUpload.cfm',
                secureuri:false,
                fileElementId:<b>'fileToUpload,createpoloroid,createmedium',</b>
                dataType: 'json',
                success: function (data, status)
Thanks!
