这是我的代码:
var request = {
origin: start,
destination: end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
现在,我想在距离该点 200 公里后放置一个标记origin: start
:这可能吗?
