是否有办法消除早期版本的<代码>XPCNativeWrapper的物体(前版本3.6.2)?
每一物体在<代码>XPCNativeWrapper.unwrap上通过时,均可在功能上对等。 例如,如果你知道你的窗户是个包裹的物体,那么“真实”如下:
XPCNativeWrapper.unwrap(window) === window.wrappedJSObject // => true
XPCNativeWrapper.unwrap, 如果你不知道你会重新处理 wrap物体,则更安全。 例如,以下是“真实”:
var test = [1, 2, 3];
XPCNativeWrapper.unwrap(test) === test // => true
......但这是“false”(在使用同一阵列时):
XPCNativeWrapper.unwrap(test) === test.wrappedJSObject // false
