I thought it would be as simple as using the parent selector, however the following code:

var element = parent.document.getElementById('divID');

Generates the following error:

c3runtime.js:461 Error executing JavaScript: ReferenceError: parent is not defined
 at eval (eval at ExecJs (c3runtime.js:461), <anonymous>:1:15)
 at C3.Plugins.Browser.Instance.ExecJs (c3runtime.js:461)

Any help would be greatly appreciated

Embedded with an iframe? Because iframes are generally supposed to be enclosed systems. It is possible to post messages between iframes and parent documents.

I'm aware of postmessage, however as both the parent and frame are on the same domain, I was hoping I could avoid it (otherwise what's the point of the parent document selector?)

It's worth noting that this works fine when it's two standard webpages pages:

Hmm so I tried these
let test = parent.document.getElementById('theid'); let test2 = parent.document; console.log(test, test2);

This works for me, you can check the console here:

Maybe you just have a typo somewhere?
