Is there a way to check if geolocation has been DECLINED with Javascript?

Question

I need JavaScript to display a manual entry if geolocation is declined.

What I have tried:

Modernizr.geolocation
navigator.geolocation

Neither describes if user has previously declined access to geolocation.

Answer 1

Without prompting the user, you can use the new permission api this is available as such:

navigator.permissions.query({ name: 'geolocation' })
.then(console.log)
