GeolocationCoordinates: toJSON() method
Baseline
2024
Newly available
Since September 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The toJSON() method of the GeolocationCoordinates interface is a serializer; it returns a JSON representation of the GeolocationCoordinates object.
Syntax
js
toJSON()
Parameters
None.
Return value
A JSON object that is the serialization of the GeolocationCoordinates object.
Examples
Using the toJSON() method
In this example, calling position.coords.toJSON() returns a JSON representation of the GeolocationCoordinates object.
js
navigator.geolocation.getCurrentPosition((position) => {
console.log(position.coords.toJSON());
});
This would log a JSON object like so:
json
{
"accuracy": 12.0,
"latitude": 53.0,
"longitude": 8.0,
"altitude": null,
"altitudeAccuracy": null,
"heading": null,
"speed": null
}
To get a JSON string, you can use JSON.stringify(position.coords) directly; it will call toJSON() automatically.
