The toJSON() method of the GeolocationCoordinates interface is a serializer; it returns a JSON representation of the GeolocationCoordinates object.
toJSON()
None.
A JSON object that is the serialization of the GeolocationCoordinates object.
toJSON() methodIn this example, calling position.coords.toJSON() returns a JSON representation of the GeolocationCoordinates object.
navigator.geolocation.getCurrentPosition((position) => {
console.log(position.coords.toJSON());
});
This would log a JSON object like so:
{
"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.
