check if location setting has been turned off in users browser

Question

I would like to hide() or show() a button that allows users to use their current location based on whether or not they are currently allowing location to be used in their browser setting. the below code only checks if the browser supports geolocation and not whether or not the particular user is allowing it.

if (navigator.geolocation)  {    navigator.geolocation.getCurrentPosition(showPosition);    } else  {  x.innerHTML="Geolocation is not supported by this browser.";}  }  

Is there a boolean value that I can detect for their browser setting letting me know if location is currently allowed?

thanks for any suggestions.

Have you read http://www.w3schools.com/html/html5_geolocation.asp

What you want to do is check the errors to see if they allowed it or denied the request.

function getLocation() {   if (navigator.geolocation) {     navigator.geolocation.getCurrentPosition(showPosition,showError);   } else {     x.innerHTML = "Geolocation is not supported by this browser.";   } }  function showPosition(position) {   x.innerHTML = "Latitude: " + position.coords.latitude + "<br>Longitude: " + position.coords.longitude;     }  function showError(error) {   switch(error.code) {     case error.PERMISSION_DENIED:       x.innerHTML = "User denied the request for Geolocation."       break;     case error.POSITION_UNAVAILABLE:       x.innerHTML = "Location information is unavailable."       break;     case error.TIMEOUT:       x.innerHTML = "The request to get user location timed out."       break;     case error.UNKNOWN_ERROR:       x.innerHTML = "An unknown error occurred."       break;   } }

The below code will allow you to check the permission status without invoking the navigator.geolocation permission request.

Browsers Supported: Chrome(43+), Firefox(46+), Edge and Opera.

Unsupported: Safari(mac, ios), Internet explorer, Android webview.

    navigator.permissions && navigator.permissions.query({name: 'geolocation'})     .then(function(PermissionStatus) {         if (PermissionStatus.state == 'granted') {               //allowed         } else if (PermissionStatus.state == 'prompt') {               // prompt - not yet grated or denied         } else {              //denied         }     }) 

Here is the Reference Link.

Compatibility on other browsers is unknown. I haven't tested it myself but please feel to test yourself and comment below.
