Question

If my page is buried several iframes deep, is it possible to count how many levels down I am (cross-domain)?

(I’m pretty sure the answer is “no”.)

Answer 1

No, I’m almost certain there’s no way to do that.

You might try something like

var current = window;
while (current.parent != current) {
    current = current.parent;
}

, but I suspect you will fail with multiple domains, due to same origin policy.

Might be worth a shot, though. Maybe access is blocked to document contents only, and not to window object.
