根据地名定位谷歌MAP

许多时候，我们必须通过经纬度来定位地图，有没有办法通过地面直接定位。
其中的address = 'Paris, France';即位定位到巴黎。
代码如下

<div id="map-canvas"></div>
<style type="text/css">#map-canvas {
    height: 400px;
}</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3&sensor=false"></script>
<script type="text/javascript">
    
    var geocoder;
var map;

function initialize() {
    
    geocoder = new google.maps.Geocoder();
    
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var mapOptions = {
        zoom: 8,
        center: latlng
    };
    
    map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
    
    // Call the codeAddress function (once) when the map is idle (ready)
    google.maps.event.addListenerOnce(map, 'idle', codeAddress);
}

function codeAddress() {
    
    // Define address to center map to
    var address = 'Paris, France';
    
    geocoder.geocode({
        'address': address
    }, function (results, status) {
        
        if (status == google.maps.GeocoderStatus.OK) {
            
            // Center map on location
            map.setCenter(results[0].geometry.location);
            
            // Add marker on location
            var marker = new google.maps.Marker({
                map: map,
                position: results[0].geometry.location
            });
            
        } else {
            
            alert("Geocode was not successful for the following reason: " + status);
        }
    });
}
initialize();
</script>
