This is an Angular project. On my page A, I have a link that links to a page of a different origin, HTML as below:

...
<a href="https://another.origin"> PAGE B </a>
...

A user opened page B into a new window from page A. At this moment, A is still opened.

Now I want to post a message to B, like this referenceOfB.postmessage(msg, bOrigin) So I need to get a reference to B.

I tried
window.open to get a reference to B but get null, not sure if this is the right way to approach it. Can anyone give some hints about how to do that?

You can use window.open to spawn a new window - this function returns a reference to the spawned window. You can then post a message to is using
postmessage.

var w = window.open('https://google.com')
w.postMessage('hello', "*"); // can use target domain instead of *

  by a user on your site? You have to intercept his perceived link click and use window.open instead, I would think.
