GeolocationCoordinates
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The GeolocationCoordinates
interface represents the position and altitude of the device on Earth, as well as the accuracy with which these properties are calculated.
The geographic position information is provided in terms of World Geodetic System coordinates (WGS84).
Instance properties
The GeolocationCoordinates
interface doesn't inherit any properties.
GeolocationCoordinates.latitude
Read only-
Returns a
double
representing the position's latitude in decimal degrees. GeolocationCoordinates.longitude
Read only-
Returns a
double
representing the position's longitude in decimal degrees. GeolocationCoordinates.altitude
Read only-
Returns a
double
representing the position's altitude in meters, relative to nominal sea level. This value can benull
if the implementation cannot provide the data. GeolocationCoordinates.accuracy
Read only-
Returns a
double
representing the accuracy of thelatitude
andlongitude
properties, expressed in meters. GeolocationCoordinates.altitudeAccuracy
Read only-
Returns a
double
representing the accuracy of thealtitude
expressed in meters. This value can benull
if the implementation cannot provide the data. GeolocationCoordinates.heading
Read only-
Returns a
double
representing the direction towards which the device is facing. This value, specified in degrees, indicates how far off from heading true north the device is.0
degrees represents true north, and the direction is determined clockwise (which means that east is90
degrees and west is270
degrees). Ifspeed
is0
or the device is unable to provideheading
information,heading
isnull
. GeolocationCoordinates.speed
Read only-
Returns a
double
representing the velocity of the device in meters per second. This value can benull
.
Instance methods
The GeolocationCoordinates
interface doesn't inherit any methods.
GeolocationCoordinates.toJSON()
-
Returns a JSON representation of the
GeolocationCoordinates
object and enables serialization withJSON.stringify()
.
