Javascript中的反向地理編碼返回MissingKeyMap錯誤

Question

我試圖獲取訪問我的網頁的客戶的格式化地址。

爲此，我寫了函數獲取經緯度，然後將其地址解析爲格式化地址。

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> 
<script> 
function coordinates_to_address(lat, lng) { 
    var latlng = new google.maps.LatLng(lat, lng); 
    var geocoder= new google.maps.Geocoder(); 
    geocoder.geocode({'latLng': latlng}, function(results, status) { 
     if(status == google.maps.GeocoderStatus.OK) { 
      if(results[0]) { 
       $('#address_current').text(results[0].formatted_address); 
      } else { 
       alert('No results found'); 
      } 
     } else { 
      var error = { 
       'ZERO_RESULTS': 'No address' 
      } 

      // alert('Geocoder failed due to: ' + status); 
      $('#address_new').html('<span class="color-red">' + error[status] + '</span>'); 
     } 
    }); 
} 

navigator.geolocation.getCurrentPosition(function(location) { 
    console.log(location.coords.latitude); 
    console.log(location.coords.longitude); 
    console.log(location.coords.accuracy); 
    var lat= location.coords.latitude; 
    var long= location.coords.longitude 
    coordinates_to_address(lat, long); 
}); 

</script> 

日誌顯示輸出Lat Long網

10.8888888888888888 
    76.43923530000001 
    40 

但此函數返回一個錯誤：

Google Maps API error: MissingKeyMapError https://developers.google.com/maps/documentation/javascript/error-messages#missing-key-map-error 
    http://maps.google.com/maps/api/js?sensor=false 
    Line 34 

有沒有更簡單的方法來獲取經緯度長的格式的地址？

Answer 1

Keys are now required with the Google Maps Javascript API v3（但傳感器參數不是）。
