将 Window 对象存储在本地存储中

Storing the Window Object in local storage(将 Window 对象存储在本地存储中)

问题描述

我需要持久化窗口对象的能力.我试图对窗口对象进行字符串化，但在尝试将窗口对象转换为 JSON 时收到错误消息.将循环结构转换为 JSON"错误.无论如何我可以将 window.open 中的 window 对象存储在本地商店中吗?

I need the ability to persist the window object. I tried to stringify the window object but I received and error when trying to convert the window object to JSON. "Converting circular structure to JSON" error. Is there anyway I can store the window object from a window.open in local store?

var myWindow = window.open("file:///D:/Temp/teststorage.html", "MsgWindow", "width=200, height=100");
localStorage.setItem('Window', JSON.stringify(myWindow));

推荐答案

你不能在本地存储中持久化 window 对象.

You can't persist a window object in local storage.

在本地存储中只能以字符串的形式存储数据，没有办法将window对象变成字符串以便重新创建相同的window对象.
