如果您想在地图上放置标记place_id：'ChIJN1t_tDeuEmsRUsoyG83frY4'的地方，您需要向 getDetails 请求 PlaceService

  var service = new google.maps.places.PlacesService（map）; 
 service.getDetails（{
 placeId：'ChIJN1t_tDeuEmsRUsoyG83frY4'
}，function（result，status）{
 var marker = new google.maps.Marker（{
 map：map，
 place：{
 placeId：'ChIJN1t_tDeuEmsRUsoyG83frY4'，
 location：result.geometry.location 
} 
}）; 
}） ;

I am trying to place a marker onto Google Maps using its PlaceID. I have the map working and displaying and can also add markers (using LatLong) onto it.

The code below is what I am using to try and make the marker display using its placeID however it is not displaying.

function addPlaces(){
    var marker = new google.maps.Marker({
        place: new google.maps.Place('ChIJN1t_tDeuEmsRUsoyG83frY4'),
        map: map
    });
}

This function is called after the map has loaded.

google.maps.event.addDomListener(window, "load", addPlaces);

If you want to place a marker on the map at the place with the place_id: 'ChIJN1t_tDeuEmsRUsoyG83frY4', you need to make a getDetails request to the PlaceService

var service = new google.maps.places.PlacesService(map);
service.getDetails({
    placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4'
}, function (result, status) {
    var marker = new google.maps.Marker({
        map: map,
        place: {
            placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4',
            location: result.geometry.location
        }
    });
});

  }, function(result, status) {
    if (status != google.maps.places.PlacesServiceStatus.OK) {
      alert(status);
      return;
    }
    var marker = new google.maps.Marker({
      map: map,
      position: result.geometry.location
    });
    var address = result.adr_address;
    var newAddr = address.split("</span>,");

    infoWindow.setContent(result.name + "<br>" + newAddr[0] + "<br>" + newAddr[1] + "<br>" + newAddr[2]);
    infoWindow.open(map, marker);
  });

}

google.maps.event.addDomListener(window, 'load', initialize);
