GetCurrentPosition () method-returns data
If T succeeds, the getCurrentPosition () method returns the object. The latitude, longitude, and accuracy properties are always returned. If available, other properties below are returned.
Attribute description
Latitude of coords.latitude decimal number
Longitude of coords.longitude decimal numbers
Coords.accuracy position accuracy
Coords.altitude altitude, measured in meters above sea level
Altitude accuracy of coords.altitudeAccuracy position
Coords.heading direction, measured in degrees from due north
Coords.speed speed, in meters per second
Date / time of the timestamp response
Geolocation object-other interesting methods
ClearWatch ()-stops the watchPosition () method
The following example shows the watchPosition () method. You need a precise GPS device to test this example (such as iPhone):
Example
Var x=document.getElementById ("demo")
Function getLocation ()
{
If (navigator.geolocation)
{
Navigator.geolocation.watchPosition (showPosition)
}
Else
{
X [XSS _ clean] = "this browser does not support geolocation."
}
}
Function showPosition (position)
{
X [XSS _ clean] = "Latitude:" + position.coords.latitude +
"
Longitude: "+ position.coords.longitude
}
