Knockout ko.toJSON导致Se​​curityError权限被拒绝错误

Question

我正在尝试在observableArray上执行ko.toJSON。它工作正常但似乎在从v.3.3.0更新到v.3.4.0后停止工作。我还没有尝试回滚确认，但我想问一下是否有人会对这个问题有解释。

我的observableArray声明：

self.items = ko.observableArray();

我的失败功能：

self.items.subscribe(function (items) {  
localStorage.setItem("Cart", ko.toJSON(items));  
});

我收到以下错误消息，我将其钉入ko.toJSON：

在Chrome上：
Uncaught SecurityError: Blocked a frame with origin "http://localhost:52519" from accessing a frame with origin "https://staticxx.facebook.com". The frame requesting access has a protocol of "http", the frame being accessed has a protocol of "https". Protocols must match.

显然没有使用任何iframe而不是Facebook。

在Firefox上：
Error: Permission denied to access property "__ko_proto__"

items是CartItem的数组，它包含一些变量，observable和一个计算。

我希望有人有解释 谢谢你的帮助。

我最后使用knockout.debug调试它。该错误与Developer Tools返回的错误消息无关。我的论点不正确，我的数组无法序列化 JavaScript之美。
