PermissionStatus: change event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Note: This feature is available in Web Workers.
The change event of the PermissionStatus interface fires whenever the PermissionStatus.state property changes.
Syntax
Use the event name in addEventListener():
js
addEventListener("change", (event) => { })
Alternatively, assign to the event handler property of the interface:
js
onchange = (event) => { }
Event type
A generic Event.
Example
js
navigator.permissions
.query({ name: "geolocation" })
.then((permissionStatus) => {
console.log(`geolocation permission state is ${permissionStatus.state}`);
permissionStatus.onchange = () => {
console.log(
`geolocation permission state has changed to ${permissionStatus.state}`,
);
};
});
