JavaFX에서 Javascript로 정보 전달

정보 (lattiude, longitude)를 html webview의 Google지도에 전달하려고합니다. 문제는 응용 프로그램이 넷빈에서 시작하지 않는다는 것입니다. 그것은 반환 : 여기JavaFX에서 Javascript로 정보 전달

public class FXMLDocumentController implements Initializable { 

    @FXML public WebView Map; 





    @Override 
    public void initialize(URL url, ResourceBundle rb) { 

     URL MapURL = getClass().getResource("map.html"); 
     WebEngine WebEngine = Map.getEngine(); 
     WebEngine.load(MapURL.toExternalForm()); 
     String test = "40.3130432088809"; 
     WebEngine.executeScript("getCoordinates('40.3130432088809')"); 

    }  

}

그리고지도와 HTML :

스택 추적에 따르면이 문제는 OpenPilot의 29 행에 있습니다 (start 메서드의 어딘가에 있음). 그 코드를 보여줄 수 있습니까? –

짐을 실은. 웹 엔진로드가 완료되면 스크립트를 실행할 처리기를 지정해야합니다.

@Override 
public void initialize(URL url, ResourceBundle rb) { 

    URL MapURL = getClass().getResource("map.html"); 
    WebEngine WebEngine = Map.getEngine(); 
    WebEngine.getLoadWorker().stateProperty().addListener((ov, oldState, newState) -> { 
     if (newState == State.SUCCEEDED) { 
      WebEngine.executeScript("getCoordinates('40.3130432088809')"); 
     } 
    }); 
    WebEngine.load(MapURL.toExternalForm()); 

}

넷빈즈는이 줄이 잘못되었다고 말합니다 :'WebEngine.getLoadWorker(). addListener ((ov, oldState, newState) -> {'그건 : addlistener에 적합한 메소드가 없습니다' – user3203690

임포트 추가 : 'import javafx.concurrent.Worker.State;'고 수정했는지 확인하십시오 –
