ThetoJSON() method of theGeolocationCoordinates interface is aserializer; it returns a JSON representation of theGeolocationCoordinates object.

Syntax

toJSON()

Parameters

None.

Return value

AJSON object that is the serialization of theGeolocationCoordinates object.

Examples

Using thetoJSON() method

In this example, callingposition.coords.toJSON() returns a JSON representation of theGeolocationCoordinates 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 useJSON.stringify(position.coords) directly; it will calltoJSON() automatically.
