Prevent map scroll on mobile devices?

Found this code on the forum that works great when accessing the page on desktop devices. But it doesn’t seem to prevent scrolling on mobile devices. How can I solve this?

var myOptions = {
scrollwheel: false,
zoom:”.$zoom.”,
mapTypeControl:true,
mapTypeId:google.maps.MapTypeId.”.$type.”,
mapTypeControlOptions:{style:google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl:true,
navigationControlOptions:{style:google.maps.NavigationControlStyle.SMALL},
center:latlng
};
