地图反向编码

1.调用Google的接口反向编码.

<script type="text/javascript"        src="http://maps.google.com/maps/api/js?sensor=false&language=en"></script>  var ll = new google.maps.LatLng(latlng.lat, latlng.lng);    var geocoder = new google.maps.Geocoder();    geocoder.geocode({'latLng':ll}, function (results, status){        if (status == google.maps.GeocoderStatus.OK) {            console.log(results[1] )            if (results[1]) {                var info = results[1].address_components;                var countryName = info[info.length - 1].long_name;}}
