<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function body_onLoad() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(geo_onSuccess, geo_onError);
} else {
geo_onError();
}
}
function geo_onSuccess(pos) {
document.getElementById("timestamp").innerHTML = new Date().toLocaleString();
document.getElementById("accuracySpan").innerHTML = pos.coords.accuracy;
document.getElementById("altitudeSpan").innerHTML = pos.coords.aktitude;
document.getElementById("altitudeAccuracySpan").innerHTML = pos.coords.altitudeAccuracy;
document.getElementById("headingSpan").innerHTML = pos.coords.heading;
document.getElementById("latitudeSpan").innerHTML = pos.coords.latitude;
document.getElementById("longitudeSpan").innerHTML = pos.coords.longitude;
document.getElementById("speedSpan").innerHTML = pos.coords.speed;
}
function geo_onError() {
alert("Unable to get latitude/longitude, or browser does not support geolocation API.");
}
</script>
</head>
<body onload="body_onLoad();">
<h1>navigator.geolocation</h1>
