HTML5一步一步走――地理应用(六)
地理信息应用获取自己的位置：

function $(id) { return document.getElementById(id); }
window.onload = function() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(
        function(pos) { 
          $("lat").innerHTML = pos.coords.latitude;//纬度
          $("lon").innerHTML = pos.coords.longitude;//经度
          $("alt").innerHTML = pos.coords.altitude;//高度
          $("accuracy").innerHTML = pos.coords.accuracy;
          $("altitudeAccuracy").innerHTML = pos.coords.altitudeAccuracy;
          $("heading").innerHTML = pos.coords.heading;
          $("speed").innerHTML = pos.coords.speed;
          $("timestamp").innerHTML = pos.timestamp;
            // $("status").innerHTML = JSON.stringify(pos);
        },
        function() {},
        {enableHighAccuracy:true, maximumAge:600000}
    );
  } else {
    $("status").innerHTML = 
      'No Geolocation support for your Browser';
  }
}
