How to open a window and pass html to it?

Question

JavaScript

var html = ""
var окно = window.open("about:blank", 'name')
окно.document.write(html)

— the code works, but through time.
The first time you run it, everything opens fine, but when you start it again, the tab becomes empty.
It is necessary that html is repeatedly opened in the same window.

Answer 1

The documentation says:
As long as you do not create a different name for each new window, the call will go to the already open window, and access to its DOM is possible only if security requirements are met. For this reason the code fulfills only at opening.

Answer 2

Make the modal window better and write any html there, because in fact it will be a div that is displayed and hidden using html and do not use Russian characters in variable names)
