Geolocation.getCurrentPosition()

The Geolocation.getCurrentPosition() method is used to get the current position of the device.

navigator.geolocation.getCurrentPosition(success[, error[, [options]])

success

A callback function that takes a GeolocationPosition object as its sole input parameter.

error Optional

An optional callback function that takes a GeolocationPositionError object as its sole input parameter.

options Optional

An optional PositionOptions object.
Options includes:

• maximumAge: integer (milliseconds) | infinity - maximum cached position age.
• timeout: integer (milliseconds) - amount of time before the error callback is invoked, if 0 it will never invoke.
• enableHighAccuracy: false | true

var options = {
  enableHighAccuracy: true,
  timeout: 5000,
  maximumAge: 0
};

function success(pos) {
  var crd = pos.coords;

  console.log('Your current position is:');
  console.log(`Latitude : ${crd.latitude}`);
  console.log(`Longitude: ${crd.longitude}`);
  console.log(`More or less ${crd.accuracy} meters.`);
}

function error(err) {
  console.warn(`ERROR(${err.code}): ${err.message}`);
}

navigator.geolocation.getCurrentPosition(success, error, options);
