Javascript 点击 Google Maps API 并获取地址

Click on Google Maps API and get the address

提问by Basj

The following code allows to get the coordinates, on click. But how to get the address or city name or region name or country on click on the map, with Google Maps API?

以下代码允许在单击时获取坐标。但是如何使用 Google Maps API 在地图上点击获取地址或城市名称或地区名称或国家？

var myLatlng = new google.maps.LatLng(41.38,2.18);
var myOptions = { zoom: 13, center: myLatlng}
var map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);

google.maps.event.addListener(map, 'click', function(event) {alert(event.latLng);});

html, body, #map-canvas {
    height: 100%;
    width: 100%;
    margin: 0px;
    padding: 0px
}

<script src="https://maps.googleapis.com/maps/api/js?sensor=false&libraries=geometry,places&ext=.js"></script>
<div id="map-canvas"></div>

You can pass the event.latLngtrough the Geocoder to get the address:

您可以通过event.latLngGeocoder 来获取地址：

var myLatlng = new google.maps.LatLng(41.38, 2.18);
var myOptions = {
  zoom: 13,
  center: myLatlng
}
var map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
var geocoder = new google.maps.Geocoder();

google.maps.event.addListener(map, 'click', function(event) {
  geocoder.geocode({
    'latLng': event.latLng
  }, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      if (results[0]) {
        alert(results[0].formatted_address);
      }
    }
  });
});

you cannot get only one result by only lat,lng from google api, but you could get some results by search lat,lng and a keyword in a radius.

您不能仅通过 lat,lng 从 google api 获得一个结果，但您可以通过搜索 lat,lng 和半径范围内的关键字获得一些结果。

the only way get specific place information you need search by its placeID

获取您需要通过 placeID 搜索的特定地点信息的唯一方法

    var myLatlng = new google.maps.LatLng(41.38,2.18);
var myOptions = { zoom: 13, center: myLatlng}
var map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
var infoWindow;
var service;
google.maps.event.addListener(map, 'click', function(event) {
    service = new google.maps.places.PlacesService(map);
    infoWindow = new google.maps.InfoWindow();
    var request = {
        location: event.latLng,
        keyword: 'food',
        radius:500
    };
    service.radarSearch(request, callback);

});
function callback(results, status) {
    if (status !== google.maps.places.PlacesServiceStatus.OK) {
        console.error(status);
        return;
    }
    for (var i = 0, result; result = results[i]; i++) {
        addMarker(result);
    }
}

function addMarker(place) {
    var marker = new google.maps.Marker({
        map: map,
        position: place.geometry.location,
        icon: {
            url: 'http://maps.gstatic.com/mapfiles/circle.png',
            anchor: new google.maps.Point(10, 10),
            scaledSize: new google.maps.Size(10, 17)
        }
    });

    google.maps.event.addListener(marker, 'click', function() {
        service.getDetails(place, function(result, status) {
            if (status !== google.maps.places.PlacesServiceStatus.OK) {
                console.error(status);
                return;
            }
            infoWindow.setContent(result.name+"<br>"+result.formatted_address+"<br>"+result.formatted_phone_number);
            infoWindow.open(map, marker);
        });
    });
}
