Question

我正在尝试使用Google Map API做一个小项目，我的问题是当我点击它时，我找不到如何在地图上获取地点的名称。按地方我的意思是表示为内部有图片的圆圈（博物馆，餐馆，纪念碑等） Like this

在这张图片中，地图的默认动作是当我点击它时打开一个信息窗口，带有地点的名称，这正是我想要的但是我没有“提取”名称的解决方案（在其他地方使用它）因为这是一个默认的反应......

我尝试使用以下代码获取它：

var service = new google.maps.places.PlacesService(map);

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

function getAddress(latLng) {
    geocoder.geocode( {'latLng': latLng},
    function(results, status) {
        if(status === google.maps.GeocoderStatus.OK) {
            var arrayLength = results.length;

            for (var i = 0; i < arrayLength; i++) {
                var request = {
                    placeId: results[i].place_id_id
                };
                service.getDetails(request, callback);
            }
        }
    });
}

function callback(place, status) {
    if (status == google.maps.places.PlacesServiceStatus.OK) {
        console.log(place);
    }
}

但唯一准备好的东西是地址（例如：“37 Phillip St，Sydney NSW 2000，Australie”），但从来没有这个地方的名字。

我在谷歌上找不到任何东西，看起来真的很奇怪......

感谢您的帮助！：）

As per the code you have provided, you are using the PlaceDetails from which you can actually already get the data you need. As per the Places Details Results docs:

A successful getDetails() call returns a PlaceResult object.

Wherein PlaceResult object pretty much has the info that you might need. Haven't tested it out, but it has the address_components property that has a structure like so (referred to Geocoder response sample on this one):

"address_components" : [
            {
               "long_name" : "1600",
               "short_name" : "1600",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Amphitheatre Pkwy",
               "short_name" : "Amphitheatre Pkwy",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Mountain View",
               "short_name" : "Mountain View",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Santa Clara County",
               "short_name" : "Santa Clara County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "United States",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "94043",
               "short_name" : "94043",
               "types" : [ "postal_code" ]
            }
         ]

and also the name property which is simply described in the docs as:

The place's name.

Just tweak around the results of the PlaceDetails request and I'm pretty sure you'll find it. Hope this helps. Good luck.
