IE mode parent open Edge Chromium mode child window, goes missing?

Copper Contributor


In parent Edge browser, running IE mode, running this code

function openLinkInIE(url){"microsoft-edge:"+ url, 'childWindow');

 The new Edge browser opens, running in Edge Chromium mode.

Check in console, is empty.


Question 1: Why is empty in child ?

Question 2: Is it possible to use window.postMessage from parent IE mode browser window to Edge Chromium mode child browser?

Question 3: Is there some other way to to window.postMessage from IE mode parent to Edge Chromium mode child? Or some workaround?


When I do IE mode parent open IE mode child, is not missing, as its defined by parent.

The same goes for Chromium mode parent to Chromium mode child, is is not missing.

I suspect its a problem with the missing in child because using window.postMessage depends on the child window name, defined when using

I'm still trying to get this to work.


For window.postMessage, it does not work when Edge IE mode opens(parent) a , a Edge Chromium mode child.


Is there a way to make this work? or workaround ? Or example?
