This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The PermissionStatus.onchange event of the PermissionStatus interface is called whenever the PermissionStatus.state property changes.
Syntax
PermissionStatus.onchange = function() { ... }
PermissionStatus.addEventListener('change', function() { ... })
Example
navigator.permissions.query({name:'geolocation'}).then(function(permissionStatus) {
console.log('geolocation permission state is ', permissionStatus.state);
permissionStatus.onchange = function() {
console.log('geolocation permission state has changed to ', this.state);
};
});
