c# - Is it possible to have javascript communication between 2 WebBrowsers in winform -

I have a winform with 2 webbrowser controls Is a page a way to communicate with others?

For example in HTML and frame, a page can use the window painter.frame [1]. For example, documents.

Not directly, because these are two separate browser examples. You can write some of your own communication layers. Obviously you have to prepare the websites you are also showing for it.
