使用Javascript从Google Places搜索api获取纬度和经度

如何使用谷歌地图搜索框api从搜索到的位置获取经度和纬度.

 我使用与谷歌演示相同的代码 – https://developers.google.com/maps/documentation/javascript/examples/places-searchbox

搜索代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

<script type="text/javascript">     //自动搜索     function initMap() {         var input = document.getElementById('address_search');         var places = new google.maps.places.Autocomplete(input);         google.maps.event.addListener(places, 'place_changed', function () {                 var place = places.getPlace();                 var address = place.formatted_address;                 var latitude = place.geometry.location.A;                 var longitude = place.geometry.location.F;                 var mesg = "Address: " + address;                 mesg += "nLatitude: " + latitude;                 mesg += "nLongitude: " + longitude;                 console.log(place);                 GetLatlong();         });     }     //根据google places搜索api获取经纬度     function GetLatlong()     {         var geocoder = new google.maps.Geocoder();         var address = document.getElementById('address_search').value;           geocoder.geocode({ 'address': address }, function (results, status) {             if (status == google.maps.GeocoderStatus.OK) {                 var latitude = results[0].geometry.location.lat();                 var longitude = results[0].geometry.location.lng();                 alert(latitude+","+longitude);             }         })     } </script> <script async defer src="https://maps.googleapis.com/maps/api/js?key=xxxxx&libraries=places&callback=initMap"> </script>
