I tried with JSON and a lot of different libraries :

var popupVar = window.open('url', 'name');
var serializedString = JSON.encode(popupVar);
var serializedString = popupVar.toJSONString();
...

Every time I have errors. I could catch it with IE, and it says : [Object error]. Great :p
In Firefox it just crashs it...

I did'nt find any real example on serializing JS "native" objects, only JS "created" objects (like var Person = { this.id; this.name; })

Does someone achieve it ? Know how to serialize this popupVar ?

Thanks a lot

AFAIK, you simply can't. To put it in simple terms, the Javascript variables disappear after a page reload. After all Javascript is a client side technology.

A work around would be to store all the information you need to maintain inside a cookie i.e. whether the child window was open or not and if yes then what were it's contents; at the same time being aware of the 4KB limit imposed on the cookie size.

However, if you could persist the current window to the next reload in the browser, you could also persist reference to open windows, and other objects (dependents).
