未捕获的DOMException:无法在"Window"上执行"postMessage":无法克隆对象

Question

我正试着打电话

parent.postMessage(obj, 'whatever');

在iframe中,我收到此错误: Uncaught DOMException: Failed to execute 'postMessage' on 'Window': An object could not be cloned.

Answer 1

事实证明我传递的对象有方法,这就是错误消息所说的原因An object could not be cloned.

为了解决这个问题,您可以执行以下操作:

obj = JSON.parse(JSON.stringify(obj));
parent.postMessage(obj, 'whatever');
