GeolocationCoordinates: toJSON() method

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

undefined

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.
