The main difference between the code in the two pages (parent and iframe) is the method of sending messages. Recieving messages is done using the same code.

parent

Send message to iframe using iframeEl.contentWindow.postMessage

Recieve message using window.addEventListener('message')

iframe

Send message to parent window using window.parent.postMessage

Recieve message using window.addEventListener('message')
