我的问题如何在main.java和点击注册按钮中加载注册表单我需要切换registerform

我将controller，onaction，fx：id设置为login.fxml

Answer 1

AnchorPane中的login.fxml将成为父级，并且将成为所有其他元素的容器，我将anchorPane设置为id Anchorpane {1}}（你可以选择你的）。完成后，您只需要在控制器类中添加这些代码部分

@FXML AnchorPane anchorPane;

@FXML
private void RegisterStage() throws IOException {
    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("reg.fxml"));
    Pane registerPane = (Pane) fxmlLoader.load();
    try {
        anchorPane.getChildren().clear();
        anchorPane.getChildren().add(registerPane);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

将reg.fxml替换为您要加载的所需fxml。
