I am using chrome 58. I do not want to use " var otherwindow = window.open('', 'targetwindow', '');" to get the reference since it opens a new "about:blank" web page. I want to use an existing open window which internally I have already established a name via javascript using: " window.name = 'targetwindow'; " Once the otherwindow exists I can then use otherwindow.postMessage( . . .); to send the message to the target window where the eventlistener exists with that named ('targetwindow') window.
I do not want to use an iframe. I do not want to use parent/child. I do not want to use anything other than an existing open and internally named window.
I have not found any W3C defined method for obtaining the required reference.
Also, I tried using "Broadcast Channel" instead and had no luck.
