[Srdjan Dejanovic]

Hi,
I have u javascript code:

DeviceHelper = function () {
    return {
        HandheldDevicesScrollPrevent: function () {
            $(document).on("touchmove", "body.scroll-disabled, body.no-overflow", function (e) {
                e.preventDefault();
                return false;
            });
        }
    }
}();
