How can I prompt a user for their geo-location in javascript if they\'ve blocked my request in the past? (using navigator.geolocation.getCurrentPosition).
For exampl
You can't.
The user must manage their browser settings manually because your site is added to a blacklist when denied location permissions.
Here are instructions for Chrome users to manage their location permissions: https://support.google.com/chrome/answer/142065?hl=en
As mentioned by @matthew-shwery, you can not change the permission.
the best you could do is check for the permission and notify the user is the permission is denied
navigator.permissions.query({
name: 'geolocation'
}).then(function(result) {
if (result.state == 'granted') {
report(result.state);
geoBtn.style.display = 'none';
} else if (result.state == 'prompt') {
report(result.state);
geoBtn.style.display = 'none';
navigator.geolocation.getCurrentPosition(revealPosition, positionDenied, geoSettings);
} else if (result.state == 'denied') {
report(result.state);
geoBtn.style.display = 'inline';
}
result.onchange = function() {
report(result.state);
}
});
