google.maps.places 未定义 [英] google.maps.places is undefined

问题描述

我有一个网站，可以通过 Google 地图、街道和地点加载一个位置的 3 个单独视图".

I have a website that loads 3 seperate "views" of a location via Google Maps, Street and Places.

请看下面我的代码:

我终于让地图和街景正常工作了，但在这方面有点挣扎.

I have finally gotten Maps and Street view to work properly but am struggling a bit with this one.

我有一个与地图显示相同但添加了地点的选项卡.

I have a tab that displays the same as map but with places added.

<script type="text/javascript" 
  src="http://maps.googleapis.com/maps/api/js?v=3&key=....&sensor=false&callback=initializeMap"></script>

<script type="text/javascript">
var myLattitude = <?php echo $data["lattitude"]; ?>;
var myLongitude = <?php echo $data["longitude"]; ?>;
var poiMap;
var infowindow;

function initializePoi() {
            var poiCentre = new google.maps.LatLng(myLattitude, myLongitude);

            poiMap = new google.maps.Map(document.getElementById('poi-canvas'), {
                center: poiCentre,
                zoom: 15
            });

            var request = {
                location: poiCentre,
                radius: 500,
                types: ['store']
            };
            infowindow = new google.maps.InfoWindow();
            var service = new google.maps.places.PlacesService(poiMap);
            service.nearbySearch(request, callback);
        }

        function callback(results, status) {
            if (status == google.maps.places.PlacesServiceStatus.OK) {
                for (var i = 0; i < results.length; i++) {
                    createMarker(results[i]);
                }
            }
        }

        function createMarker(place) {
            var placeLoc = place.geometry.location;
            var marker = new google.maps.Marker({
                map: poiMap,
                position: place.geometry.location
            });

            google.maps.event.addListener(marker, 'click', function() {
                infowindow.setContent(place.name);
                infowindow.open(poiMap, this);
            });
        }

现在这已正确初始化，但控制台抛出以下错误:类型错误:google.maps.places 未定义

Now This initializes properly but the console throws the following error: TypeError: google.maps.places is undefined

我只想知道为什么会出现这个错误，我喜欢干净无错误的代码.

I just want to know why I get this error, I like having clean errorless code.

这些地方确实显示正确，一切正常.

The places do actually show up properly and everything.

推荐答案

您应该在 Google API URL 中添加选项 libraries=places

You should add the option libraries=places in the Google API URL

在您的情况下，您应该替换以下内容:

In your case you should replace the following:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3&key=....&sensor=false&callback=initializeMap"></script>

有了这个:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3&key=....&sensor=false&callback=initializeMap&libraries=places"></script>

查看src=""
