字符串化DOMWindow对象 [英] Stringify DOMWindow object

问题描述

由于某种原因，我似乎无法在DOMWindow对象上使用JSON.stringify.例如:

For some reason I seem unable to use JSON.stringify on a DOMWindow object. For example:

console.log(window.self); // Outputs a hierarchical DOMWindow object
console.log(JSON.stringify(window.self)); // Outputs nothing - not even an error

alert(window.self); // Alerts "[object DOMWindow]"
alert(JSON.stringify(window.self)); // Again nothing - not even an error

在Safari和Chrome上进行了测试.有谁知道我如何实现这一目标?

Tested on Safari and Chrome. Does anyone have any ideas how I can achieve this?

推荐答案

为什么要序列化DOM?如果需要，可以在Crescent的链接中查找.无法序列化(字符串化)窗口对象的原因是因为它包含循环引用，并且JSON.stringify默认情况下不支持它们.

Why would you want to do serialize the DOM? If you must, Crescent's link is where you need to look. The reason you cannot serialize (stringify) the window object is because it contains circular references, and JSON.stringify does not support them by default.
