使用带有FXML的JavaFX创建带有删除按钮的多个TextFields

import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;

import java.net.URL;
import java.util.ResourceBundle;

public class SampleController implements Initializable {

    @FXML
    private VBox container;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        // 初始化界面
        addTextField();
    }

    @FXML
    private void addTextField() {
        // 创建一个新的TextField和删除按钮
        TextField textField = new TextField();
        Button deleteButton = new Button("删除");
        deleteButton.setOnAction(event -> container.getChildren().remove(textField));

        // 将TextField和删除按钮添加到容器中
        container.getChildren().addAll(textField, deleteButton);
    }
}

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

public class MainApp extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("JavaFX App");
        primaryStage.setScene(new Scene(root, 300, 200));
        primaryStage.show();
    }

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