Geolocation.getCurrentPosition()

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

Syntax

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

Parameters

• success A callback function that takes a GeolocationPosition object as its sole input parameter.
• error Optional An optional callback function that takes a GeolocationPositionErrorobject as its sole input parameter.
• options Optional An optional object including the following parameters: maximumAge: Is a positive long value indicating the maximum age in milliseconds of a possible cached position that is acceptable to return. If set to 0, it means that the device cannot use a cached position and must attempt to retrieve the real current position. If set to Infinity the device must return a cached position regardless of its age. Default: 0. timeout: Is a positive long value representing the maximum length of time (in milliseconds) the device is allowed to take in order to return a position. The default value is Infinity, meaning that getCurrentPosition() won't return until the position is available. ** enableHighAccuracy: Is a boolean value that indicates the application would like to receive the best possible results. If true and if the device is able to provide a more accurate position, it will do so. Note that this can result in slower response times or increased power consumption (with a GPS chip on a mobile device for example). On the other hand, if false, the device can take the liberty to save resources by responding more quickly and/or using less power. Default: false.

Example

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);
