如果我将package controller;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
public class MainController {
AlertController alertController = new AlertController();
@FXML
public Label mainLabel;
@FXML
public TextField mainTextField;
@FXML
public Button mainButton;
@FXML
public void onMainButtonClicked() {
alertController.displayAlert();
alertController.setAlertLabel("Hello from MainController!");
}
}
替换为<img src="http://deskbg.com/s3/wpp/26/26833/ferocious-tiger-desktop-background.jpg" width="100%" />
它不起作用。我不想用jquery
