Javascript序列化窗口对象 [英] Javascript serialize window object

问题描述

我想序列化一个包含窗口的窗口对象，因此如果通过反序列化并重新设置其属性来刷新php页面，则在内存中保持窗口打开。可能吗？

I would like to serialize a window object that contains a window, thus to keep in memory the window open if the php page is refreshed by deserializing it and setting its properties back. Is it Possible?

例如：

object = window.open（ test.html，..）

使用场景：

当a窗口被打开，它的引用是在创建它的父窗口中进行的，但是当刷新该父窗口时，对子窗口的引用将丢失。因此，我想序列化该窗口对象并保留它以防刷新窗口。任何其他解决方案也是受欢迎的。

When a window is opened its reference is made in the parent window which created it, but when that parent window is refreshed that reference to the child window is lost. Therefore I want to serialize that window object and keep it in case the window is refreshed. Any other solution for this is also welcome.

推荐答案

不，你不能序列化一个窗口对象。这是因为窗口对象具有循环引用。对象的每个子节点都有对其父节点的引用。 JSON.stringify（）不支持循环引用。并且不要试图将引用保留在全局变量中。全局变量是全局对象的属性。此对象的属性是JavaScript程序的全局变量。当您声明一个全局JavaScript变量时，您实际要做的是定义全局对象的属性。

No, you can´t serialized a window object. And that's because a window object has circular references. Every child of an object has a reference to his parent. JSON.stringify() does not support circular references. And do not try to keep the reference in a global variable. Global variables are properties of a global object. The properties of this object are the global variables of JavaScript programs. When you declare a global JavaScript variable, what you are actually doing is defining a property of the global object.
