GeolocationCoordinates - Web APIs 编辑

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.

Properties

The GeolocationCoordinates interface doesn't inherit any properties.

GeolocationCoordinates.latitude Read only Secure context

Returns a double representing the position's latitude in decimal degrees.

GeolocationCoordinates.longitude Read only Secure context

Returns a double representing the position's longitude in decimal degrees.

GeolocationCoordinates.altitude Read only Secure context

Returns a double representing the position's altitude in meters, relative to sea level. This value can be null if the implementation cannot provide the data.

GeolocationCoordinates.accuracy Read only Secure context

Returns a double representing the accuracy of the latitude and longitude properties, expressed in meters.

GeolocationCoordinates.altitudeAccuracy Read only Secure context

Returns a double representing the accuracy of the altitude expressed in meters. This value can be null.

GeolocationCoordinates.heading Read only Secure context

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 is 90 degrees and west is 270 degrees). If speed is 0, heading is NaN. If the device is unable to provide heading information, this value is null.

GeolocationCoordinates.speed Read only Secure context

Returns a double representing the velocity of the device in meters per second. This value can be null.

Methods

The GeolocationCoordinates interface neither implements, nor inherits any method.
