地理位置是通过JavaScript地理位置API可用纬度：

Answer 2

<script type="text/javascript" src="http://maps.google.com/maps/api/js?v=3.1&sensor=true"></script> 
<script type="text/javascript"> 
    var r = confirm("We need your permission to get your location!"); 
    if (r == true) { 
     function onPositionUpdate(position) { 
      document.getElementById("txtlati").value = position.coords.latitude; 
      document.getElementById("txtlongi").value = position.coords.longitude; 
     } 
     if (navigator.geolocation) 
      navigator.geolocation.getCurrentPosition(onPositionUpdate); 
     else 
      alert("navigator.geolocation is not available"); 
    } 
    else { 
     x = "Sorry! You will be redirecting"; 
     location.href("Default.aspx"); 
    } 
    function initialize() { 
     var map = new google.maps.Map(document.getElementById("map_area")); 
     var myLatlng = new google.maps.LatLng(document.forms[0].txtlati.value, document.forms[0].txtlongi.value); 
     var myOptions = { zoom: 15, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP } 
     var map = new google.maps.Map(document.getElementById("map_area"), myOptions); 
     var marker = new google.maps.Marker({ position: myLatlng, draggable: true, flat: false, map: map, title: "Move pin to get latitude and longitude." }); 
     google.maps.event.addListener(marker, "drag", function() { 
      var latlng = marker.getPosition(); 
      document.forms[0].txtlati.value = latlng.lat(); 
      document.forms[0].txtlongi.value = latlng.lng(); 
     }); 
    } 
</script> 


<div id="map_area" style="width: 700px; height: 500px"> 
</div> 

我在div.thats它的文本框。
