获取googlemap经纬度

方法一：js

<html> 
<head> 
<link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css"/> 
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> 
<script type="text/javascript">
    var geocoder;
    var map;
    function initialize() {
        geocoder =new google.maps.Geocoder();
        var latlng =new google.maps.LatLng(31.23, 121.47);
        var myOptions = {
            zoom: 12,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        map =new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    }

    function codeAddress() {
        var address = document.getElementById("address").value;
        geocoder.geocode({ 'address': address }, function (results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
               // console.log(results[0].geometry.location)
                map.setCenter(results[0].geometry.location);
                this.marker =new google.maps.Marker({
                    title: address,
                    map: map,
                    position: results[0].geometry.location
                });
                var infowindow =new google.maps.InfoWindow({
                    content: '<strong>'+ address +'</strong><br/>'+'纬度: '+ results[0].geometry.location.Na +'<br/>经度: '+ results[0].geometry.location.Oa
                });
                infowindow.open(map, marker);
            } else {
                alert("Geocode was not successful for the following reason: "+ status);
            }
        });
    } 
</script> 
</head> 
<body onload="initialize()"> 
  <div> 
    <input id="address" type="text" value="上海市"> 
    <input type="button" value="地址解析" onclick="codeAddress()"> 
  </div> 
<div id="map_canvas" style="height:90%;top:30px"></div> 
</body> 
</html>

方法二：c#

Geo g = new Geo("地址");然后g.Latitude和g.Longtitude就是输入地址的纬度和经度
