Obviously, this will seem at first that it cannot be done, but I will state clearly that I have successfully converted the JavaScript window object to JSON. What I need help with is how to do so in a more intelligent way than I am doing now.
The process works now like this:
1) A new object is created and each key from the window key is copied to the new object. A list of commonly known keys is not added to the new object (ex. WebSocket). 2) A function called getArray recursively cleans each sub-object and saves it as JSON. The result looks like this {'key':'JSON_{....}'} or {'key':'JSON_{{'key':'JSON_{....}'}}'}. The idea is to catch the error at the smallest level so that the final JSON object is composed of key:JSON_string values. The other critical point is to catch circular objects. If the object has any of a long list of keys, then it is excluded (ex. tagName).
The problem is that this code is a bit unstable. It just recently ceased working on our site and I don't have the mind to improve it.
I will accept any solution that converts the window object to JSON (or any text format that can be decoded properly). I suggest that a partial solution, a function that will detect circular and non-JSON-encodable objects with 100%, will be the best, if it is possible. It would take a genius to produce, but I believe that it is possible.
The purpose of this is for user-sent bug reports to show the state of our JavaScript. There are too many objects to enumerate 1, by 1, and even our user-created objects contain a un-encodable objects. It is very useful and relevant for the web.
Here is current code, design pattern as described. getWindow()

{
var obj2 = {};
for (var i in window)
{
obj2[i] = 1;
}
