Question

我正在我的剧本中使用以下任务，并尝试使用“何时”设置条件以触发任务。

打击一击

ansible-playbook vdomqury.yml -e adom=In-Adom-01  -e FGT=FGVM04TM19001830  -e vdom= -vvv

如果我停止删除var vdom剧本

ansible-playbook vdomqury.yml -e adom=In-Adom-01 -e FGT=FGVM04TM19001830 -vvv

 tasks:
  - name: USE CUSTOM TYPE TO QUERY AVAILABLE SCRIPTS
    f_query:
      adom: "{{ adom }}"
      object: "custom"
      custom_endpoint: "/pm/config/adom/{{ adom }}/_package/status/{{ FGT }}/{{ vdom }}"
    register: results
    tags: ADDLAG
    when: vdom != "" 

  - name: USE CUSTOM TYPE TO QUERY AVAILABLE SCRIPTS
    f_query:
      adom: "{{ adom }}"
      object: "custom"
      custom_endpoint: "/pm/config/adom/{{ adom }}/_package/status/{{ FGT }}"
    register: results
    tags: ADDLAG
    when: vdom == "" or vdom is not defined

Answer 1

在进行比较之前，应检查是否已定义vdom，否则解释器将尝试获取其值失败。这应该可以（目前无法检查）：when: vdom is defined and vdom != ""。

Answer 2

将条件更改为

public class DragFromOneVBoxToAnother extends Application {
    private Disk sourceDisk = new Disk();
    private VBox targetVBox = new VBox();

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

    @Override
    public void start(Stage stage) {
        // Build the UI
        GridPane root = getUI();

        // Add the event handlers
        this.addEventHandlers();

        Scene scene = new Scene(root, 800, 600);
        stage.setScene(scene);
        stage.show();
    }

    private GridPane getUI() {
        GridPane pane = new GridPane();
        VBox sourceVBox = new VBox();

        sourceDisk.setWidth(90);
        sourceDisk.setHeight(20);

        sourceVBox.setStyle(" -fx-border-color:red; -fx-border-width: 1; -fx-border-style: solid;");
        targetVBox.setStyle(" -fx-border-color:green; -fx-border-width: 1; -fx-border-style: solid;");

        sourceVBox.getChildren().add(sourceDisk);
        targetVBox.getChildren().add(new Rectangle(200, 20));

        pane.setHgap(200);
        pane.addColumn(0, sourceVBox);
        pane.addColumn(1, targetVBox);
        pane.setPadding(new Insets(200, 100, 200, 100));

        return pane;
    }

    private void addEventHandlers() {
        sourceDisk.setOnMouseEntered(event -> sourceDisk.setCursor(Cursor.HAND));

        sourceDisk.setOnMousePressed(event -> {
            sourceDisk.setOrgSceneX(event.getSceneX());
            sourceDisk.setOrgSceneY(event.getSceneY());
            sourceDisk.setOrgTranslateX(sourceDisk.getTranslateX());
            sourceDisk.setOrgTranslateY(sourceDisk.getTranslateY());

            sourceDisk.setMouseTransparent(true);
            sourceDisk.setCursor(Cursor.CLOSED_HAND);
        });

        sourceDisk.setOnDragDetected(event -> sourceDisk.startFullDrag());

        sourceDisk.setOnMouseDragged(event -> {
            double offsetX = event.getSceneX() - sourceDisk.getOrgSceneX();
            double offsetY = event.getSceneY() - sourceDisk.getOrgSceneY();
            double newTranslateX = sourceDisk.getOrgTranslateX() + offsetX;
            double newTranslateY = sourceDisk.getOrgTranslateY() + offsetY;

            sourceDisk.setTranslateX(newTranslateX);
            sourceDisk.setTranslateY(newTranslateY);
        });

        sourceDisk.setOnMouseReleased(event -> {
            sourceDisk.setMouseTransparent(false);
            sourceDisk.setCursor(Cursor.DEFAULT);
        });

        targetVBox.setOnMouseDragReleased(event -> 
            targetVBox.getChildren().add(sourceDisk));
    }

    private class Disk extends Rectangle {
        private double orgSceneX;
        private double orgSceneY;
        private double orgTranslateX;
        private double orgTranslateY;

        // below, the getters and setters for all the instance variables
        // were removed for brevity
}
