How to exclude or set data sources for Geolocation API?

Question

JavaScript

At the moment I'm trying to establish a user's location with minimal participation. When calling the Geolocation API on a desktop computer, I found this:
I am in city #1. However, browsers that support the API do not return errors, and, for example, Chrome determines the city correctly, and Firefox determines my location as city #2 (at 100 km). Both cities have my ISP, which I think is GeoIP - each browser just polls its own REST service.
I would like to know - is it possible to disable GeoIP in the Geolocation API, or at least set a custom data source?

Answer 1

So do not ask the browser, use your service, which will return the coordinates to you with regular ajax.
