java - gMapsFX netscape.javascript.JSException : ReferenceError

Question

我正在尝试在我的 javafx 程序中使用 gmapsfx。

我的代码是这样的:

@Override
public void initialize(URL url, ResourceBundle rb) {
    mapView = new GoogleMapView();
    mapView.addMapInializedListener(this);
}    


    @Override
public void mapInitialized() {    
    MapOptions options = new MapOptions();
    options
        .center(new LatLong(40.7127, -74.0059))
        .mapType(MapTypeIdEnum.ROADMAP)
        .zoom(12);
    map = mapView.createMap(options);
    mapView.setKey("");
    showMarker(40.748433, -73.985656, "https://upload.wikimedia.org/wikipedia/commons/thumb/1/13/Disc_Plain_red.svg/32px-Disc_Plain_red.svg.png");
    showMarker(40.713, -74.0135, "https://upload.wikimedia.org/wikipedia/commons/thumb/0/02/Disc_Plain_blue.svg/32px-Disc_Plain_blue.svg.png");
}

/**
 * Adds a marker to the map.
 */
public void showMarker(double lat, double lng, String iconPath) {
    MarkerOptions options = new MarkerOptions();
    options
        .icon(iconPath)
        .position(new LatLong(lat, lng));
    Marker marker = new Marker(options);
    map.addMarker(marker);
} 

这是我遇到的错误。我想我只是错过了一些东西..............................................................

Answer 1

我必须在 Controller 的初始化方法中设置键mapView.setKey("");，然后 map 加载没有错误。
