GeolocationPosition: toJSON() method

{{APIRef("Geolocation API")}}

The toJSON() method of the {{domxref("GeolocationPosition")}} interface is a {{Glossary("Serialization","serializer")}}; it returns a JSON representation of the {{domxref("GeolocationPosition")}} object.

Syntax

toJSON()

Parameters

None.

Return value

A {{jsxref("JSON")}} object that is the serialization of the {{domxref("GeolocationPosition")}} object.

Examples

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:

{
  "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.
