从Java调用FXML文档中定义的javascript函数

Question

<BorderPane>
  <fx:script>
     function something() {}
  </fx:script>
</BorderPane>

FXMLLoader fxml = new FXMLLoader("F.FXML");
BorderPane root = (BorderPane)fxml.load();

是否有可能这样做：

root.something()

我想这方面的工作是在幕后使用控制器类来做一些神奇的事情，但我仍然希望用JavaScript定义函数。

请看这篇关于使用Javascript使用JavaFX的教程

public class MapApp extends Application {
    public static int ZOOM_STREET = 10;

    public static class City {
        public City(String name) {...}
        ...
    }

    public int currentZipCode;

    public void navigateTo(City location, int zoomLevel) {...}
     ....
}

和JavaScript：

function navigateTo(cityName) {
   //Assumes that the Ant task uses "myMapApp" as id for this application
   var mapApp = document.getElementById("myMapApp");
   if (mapApp != null) {
       //City is nested class. Therefore classname uses $ char 
       var city = new mapApp.Packages.testapp.MapApp$City(cityName);
       mapApp.navigateTo(city, mapApp.Packages.testapp.MapApp.ZOOM_STREET);
       return mapApp.currentZipCode;
   }
   return "unknown";
}
window.alert("Area zip: " + navigateTo("San Francisco"));

正如教程所解释的：
