您需要移动添加的方法到Slide2D构造函数之外的原型。这样，它们只定义一次，而不是每个对象实例化。

You'll need to move the methods that you adding to the prototype outside of the Slide2D constructor function. That way they only get defined once instead of with every object instantiation.

然后对于那些原型函数访问内部，如_name，_slideView等。 ..你将需要将所有的vars（目前在闭包下可访问）转换为对象本身的属性。然后使用this引用所有这些成员属性。前缀。

And then for those prototype functions to access the "internals", such as _name, _slideView, etc... You will need to convert all your "vars" (currently accessible under closure) to be properties of the object itself. Then reference all those member properties with a "this." prefix.

下面，我强制强制替换所有你的vars为this.properties。只有你需要从原型方法访问的属性和函数需要这个转换。对于内部函数（如你的animate函数），他们仍然可以使用在闭包下可访问的vars。

Below, I brute-forced replaced all your "vars" to be this.properties. Only the properties and function you need to access from the prototype methods need this conversion. For internal functions (such as your animate functions), they may still be able to use vars accessible under closure.

    this._name = name;

    this._startingTransform = transform;

    this._slideView = Titanium.UI.createView({
        backgroundImage: this._backgroundImage,
        transform: transform
    });

    this._animateInAnimation = Titanium.UI.createAnimation();
    this._animateInAnimation.transform = Titanium.UI.create2DMatrix().translate(0, 0);
