按下按钮时,应在日期选择器处显示和计数一个数字。

如果我按下“已选择”按钮,则在日期选取器中的今天日期应显示一个数字,而且我越频繁地按下“已选择”按钮,该数字应被计数。

例如:

今天我们有27.05,所以如果我按“选定”按钮,A在那里,如果我再按一次按钮,应该是2在那里,如果我第三次按按钮,应该是3在那里,以此类推。

希望有人能帮忙,提前谢谢。

我的代码:

主类

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 600, 400));
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
