HTMLGeolocationElement: isValid property
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The isValid read-only property of the HTMLGeolocationElement interface returns a boolean value indicating whether the associated <geolocation> element is valid or invalid (blocked).
When a blocker is active on a <geolocation> element, it is prevented from functioning (invalid), either temporarily or permanently, depending on the reason.
You can return the reason why it is invalid via the HTMLGeolocationElement.invalidReason property — see that page for a full list of possible reasons.
Value
A boolean value:
- If
true, the<geolocation>element is valid and functional, meaning that it can be used to request location data. - If
false, the<geolocation>element is invalid and non-functional, meaning that it can't be used to request location data.
Defaults to false.
Examples
>Basic usage
html
<geolocation></geolocation>
js
const geo = document.querySelector("geolocation");
console.log(geo.isValid);
// true, provided the `<geolocation>` element is not blocked in some way
See the HTMLGeolocationElement.invalidReason page for a more complete example involving isValid.
