HTML5一步一步走——地理应用(六)

地理信息应用获取自己的位置：
[javascript] 
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() {},  www.2cto.com
        {enablehighaccuracy:true, maximumage:600000} 
    ); 
  } else { 
    $("status").innerhtml =  
      'no geolocation support for your browser'; 
  } 
}
