通过代码，javafx关闭fxml窗口

1. 如果您还没有关闭按钮，请给它一个fx：id：

   <Button fx:id="closeButton" onAction="#closeButtonAction">

2. 在您的控制器类中：

        @FXML private javafx.scene.control.Button closeButton;    @FXML    private void closeButtonAction(){        // get a handle to the stage        Stage stage = (Stage) closeButton.getScene().getWindow();        // do what you have to do        stage.close();    }
