If both windows are in the same domain, you can create a method callBack() on your parent, and call it in the child with

Parent window:

window.callBack = function(msg) { console.log(msg); }

Child iFrame:

window.parent.callBack(msg)

If child iFrame is in a different domain then the browser will forbid this and you'll need to use window.postMessage() to send an even from the child window and window.addListener("message", function(msg) {}) to listen for these events in the parent.

Here's a good tutorial that explains how to use it ...
