    var formdata = false;

    if (window.FormData)

    {

        formdata = new FormData(form[0]);

    }

    var formAction = form.attr('action');

    $.ajax({

        url         : '/upload',

        data        : formdata ? formdata : form.serialize(),

        cache       : false,

        contentType : false,

        processData : false,
