Can I provide addresses instead of latitude and longitude to Google Maps?
I'm building an application where users provide the addresses for their listings. It's certainly not practical to ask a simple user to provide the latitu开发者_如何学Pythonde and longitude for each address he provides!
Can I provide addresses to Google Maps API instead? If so, how?
Thanks.
Yes of course. That can be done very easily, using the Geocoding Services provided by the Google Maps JavaScript API. Consider the following example:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Google Maps Geocoding Demo 1</title>
<script src="http://maps.google.com/maps/api/js?sensor=false"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 400px; height: 300px;"></div>
<script type="text/javascript">
var address = 'London, UK';
var map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.TERRAIN,
zoom: 6
});
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
},
function(results, status) {
if(status == google.maps.GeocoderStatus.OK) {
new google.maps.Marker({
position: results[0].geometry.location,
map: map
});
map.setCenter(results[0].geometry.location);
}
});
</script>
</body>
</html>
Screenshot:
You can simply substitute 'London, UK' from the address variable to any location that supports geocoding in Google Maps.
Could be refined if you provide the address with the format : var address = '# Street, City'; var address = '127 Ledbury Rd, Notting Hill, London';
