How to get a list of all physical addresses from a website?

Question

JavaScript

Greetings I'm
interested in the algorithm for obtaining all possible addresses from the site from the form. How is this generally implemented, what techniques, methods, etc.?
There is a form, here it is . There is a switch - "At the address". When you enter a street name in the form, a list of similar or exact street names is displayed, but there are many addresses collected there (street, house, building, etc.). How it is possible to "pull out" all possible addresses from there? Of course, without having direct access to the files and databases of the site.
