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));

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

You can only store data in the form of strings in local storage, and there is no way to turn the window object into a string so that you can recreate the same window object.
