子类能否响应其超级类捕获的事件?

我有一个自定义类,它是为各种目的而扩展的,下面的代码工作得很好:

class Inator {
    constructor(whichCanvas) {
        this.myCanvas = whichCanvas;
    }
}

class Ballgowninator extends Inator {
    constructor(whichCanvas) {
        super(whichCanvas);
        this.myCanvas.addEventListener("mousedown",this.handleMouseDown);
        this.myCanvas.addEventListener("mouseup",this.handleMouseUp);
    }
    handleMouseDown(e) {
        alert("ballgowninator mousedown");
    }
    handleMouseUp(e) {
        alert("ballgowninator mouseup");
    }
}

class Yodelinator extends Inator {
    constructor(whichCanvas) {
        super(whichCanvas);
        this.myCanvas.addEventListener("mousedown",this.handleMouseDown);
        this.myCanvas.addEventListener("mouseup",this.handleMouseUp);
    }
    handleMouseDown(e) {
        alert("yodelinator mousedown");
    }
    handleMouseUp(e) {
        alert("yodelinator mouseup");
    }
}

(mousedown和mouseup只是两个例子;我希望能够处理其他鼠标事件,甚至键盘事件。)

有没有方法可以将这些重复的代码移动到 Inator 超类?我假设super中的eventListener无法引用子类中的函数。

编辑:在本例中,虽然事件处理程序非常相似,但实际上,事件处理方式可能非常不同,甚至被忽略。

谢谢!
