Question

我试图将InfoWindow放在与MarkerClusterer分组的多个标记中，但没有成功。我只能生成带有infowindows或带有集群的地图;不是两个在同一时间。通过网络搜索让我更加困惑....

起点是google developers page：根据我的需要，我创建了以下代码：

    <div id="map"></div>
    <script>

      function initMap() {

        var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 5,
          center: {lat: -15.7942357, lng: -47.8821945}
        });

        // Add some markers to the map.
        // Note: The code uses the JavaScript Array.prototype.map() method to
        // create an array of markers based on a given "locations" array.
        // The map() method here has nothing to do with the Google Maps API.
        var markers = locations.map(function(location, i) {
          return new google.maps.Marker({
            position: location,
          });
        });

        // Add a marker clusterer to manage the markers.
        var markerCluster = new MarkerClusterer(map, markers,
            {imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});
      }
      var locations = [
    {lat: -19.9286,     lng: -43.93888},
    {lat: -19.85758,    lng: -43.9668},
    {lat: -18.24587,    lng: -43.59613},
    {lat: -20.46427,    lng: -45.42629},
    {lat: -20.37817,    lng: -43.41641},
    {lat: -20.09749,    lng: -43.48831},
    {lat: -21.13594,    lng: -44.26132},
      ]
    </script>
    <script src="https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/markerclusterer.js">
    </script>
    <script async defer
    src="https://maps.googleapis.com/maps/api/js?callback=initMap">
    </script>

然后我停在这里。 InfoWindow中显示的代码调用的另一个对象是＆＃34;位置＆＃34;。比我尝试的更多，最糟糕的结果是......

我想在EACH标记中添加简单的信息：每个标记只有标题和唯一的网络链接。

有人可以帮忙吗？

添加＆＃34;唯一信息＆＃34;对于您的位置数组的每个标记（就像这个问题的答案：Google Maps JS API v3 - Simple Multiple Marker Example）。

为每个标记添加一个点击监听器，用于打开包含该唯一内容的InfoWindow。

var infoWin = new google.maps.InfoWindow();
var markers = locations.map(function(location, i) {
  var marker = new google.maps.Marker({
    position: location
  });
  google.maps.event.addListener(marker, 'click', function(evt) {
    infoWin.setContent(location.info);
    infoWin.open(map, marker);
  })
  return marker;
});

function initMap() {

  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 5,
    center: {
      lat: -15.7942357,
      lng: -47.8821945
    }
  });
  var infoWin = new google.maps.InfoWindow();
  // Add some markers to the map.
  // Note: The code uses the JavaScript Array.prototype.map() method to
  // create an array of markers based on a given "locations" array.
  // The map() method here has nothing to do with the Google Maps API.
  var markers = locations.map(function(location, i) {
    var marker = new google.maps.Marker({
      position: location
    });
    google.maps.event.addListener(marker, 'click', function(evt) {
      infoWin.setContent(location.info);
      infoWin.open(map, marker);
    })
    return marker;
  });

  // Add a marker clusterer to manage the markers.
  var markerCluster = new MarkerClusterer(map, markers, {
    imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'
  });

}
var locations = [{
  lat: -19.9286,
  lng: -43.93888,
  info: "marker 1"
}, {
  lat: -19.85758,
  lng: -43.9668,
  info: "marker 2"
}, {
  lat: -18.24587,
  lng: -43.59613,
  info: "marker 3"
}, {
  lat: -20.46427,
  lng: -45.42629,
  info: "marker 4"
}, {
  lat: -20.37817,
  lng: -43.41641,
  info: "marker 5"
}, {
  lat: -20.09749,
  lng: -43.48831,
  info: "marker 6"
}, {
  lat: -21.13594,
  lng: -44.26132,
  info: "marker 7"
}, ];

google.maps.event.addDomListener(window, "load", initMap);

＆＃13;

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

＆＃13;

<script src="https://maps.googleapis.com/maps/api/js"></script>
<script src="https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/markerclusterer.js"></script>
<div id="map"></div>
