GeolocationPosition: toJSON() method

The toJSON() method of the GeolocationPosition interface is a serializer; it returns a JSON representation of the GeolocationPosition object.

Syntax

toJSON()

Parameters

None.

Return value

A JSON object that is the serialization of the GeolocationPosition object.

Examples

undefined

Using the `toJSON()` method

In this example, calling position.toJSON() returns a JSON representation of the GeolocationPosition object.

navigator.geolocation.getCurrentPosition((position) => {
  console.log(position.toJSON());
});

This would log a JSON object like so:

json

{
  "timestamp": 1717509611840,
  "coords": {
    "accuracy": 13.0,
    "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) directly; it will call toJSON() automatically.
