谷歌地图 MarkerClusterer

Question

我有一张地图，我已经运行了一段时间，只是尝试添加标记集群，因为现在地图上有足够多的标记，很难看到发生了什么。

我不想更改太多编码，因为一切正常，但无论如何我不知道如何让自定义标记进行聚类。

这是我为地图编写的 Javascript 编码：

var marker;

function pan(latlon) {
  var coords = latlon.split(",");
  var panPoint = new google.maps.LatLng(coords[0], coords[1]);
  map.panTo(panPoint)
}

var map;

function initialize() {

  var mhbrewco = {
    lat: 50.062254,
    lng: -110.71656
  }
  var mapOptions = {
    zoom: 6,
    center: new google.maps.LatLng(52.086594, -113.307591),
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    scrollwheel: false,
    mapTypeControl: false,
    streetViewControl: false
  };
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  var BrewIcon = 'http://medicinehatbrewingcompany.ca/wp-content/uploads/2016/08/favicon-32x32-1.png';

  marker = new google.maps.Marker({
    map: map,
    position: mhbrewco,
    icon: BrewIcon
  });

  var contentString = '<div id="content">' +
    '<div id="siteNotice">' +
    '</div>' +
    '<h1 id="firstHeading" class="firstHeading">Medicine Hat Brewing Company</h1>' +
    '<div id="bodyContent">' +
    '<p><b>Address:</b>' +
    ' 1366 Brier Park Dr NW' +
    ' Medicine Hat, AB T1C 1Z7</p>' +
    '<p><b>Phone:</b> <a href="tel:+14035251260">(403)525-1260</a>' +
    '</div>' +
    '</div>';

  var infowindow = new google.maps.InfoWindow({
    content: contentString
  });

  marker.addListener('click', function() {
    infowindow.open(map, marker);
  });

  jQuery(document).ready(function($) {
    $('.location').on('click', function() {
        map.setZoom(9);
      pan($(this).data('location'));
    });
  });

setMarkers(map);
}

google.maps.event.addDomListener(window, 'load', initialize);

function setMarkers(map) {

  var mcMarkers = [];

    mcMarkers.push(barMarker);

  var mcOptions = {gridSize: 50, maxZoom: 15, imagePath:'/htdocs/wp-content/themes/rhythm-child/images/m'};
  var markerCluster = new MarkerClusterer(map, mcMarkers, mcOptions);
};

在这一点上，我不确定我是否只是遗漏了一些东西......地图有效，标记在那里，他们只是不想聚集。

我将图像和 markercluster.js 文件存储在站点的服务器上，所以这也不应该成为问题。

我调用js文件的HTML代码是：

<a name="locations"></a>

<div id="map-canvas"></div>

<script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBytnwKLLyI6WBkpIltO6Qj_CaAZc_QQLI"></script>

<script src="http://www.medicinehatbrewingcompany.ca/htdocs/wp-content/themes/rhythm-child/js/markerclusterer.js"></script>

Answer 1

将每个标记添加到数组中

// Create empty array of Markers
var markers = [];

for (var i = 0; i < liquorstores.length; i++) {
  var beach = liquorstores[i];
  var barMarker = new google.maps.Marker({
    position: {
      lat: beach[1],
      lng: beach[2]
    },
    map: map,
    icon: markerlink,
    shape: shape,
    title: beach[0],
    zIndex: beach[3]
  });

  // Add marker to the array
  markers.push(barMarker);
};

然后将标记数组传递给Clusterer。

var markerCluster = new MarkerClusterer(map, markers, mcOptions);
