我正在尝试将 Google 集群添加到我的地图中,但我不知道该怎么做?我已经使用 php 中的 mysql 查询创建了带有信息框的地图及其标记。知道我正在添加更多标记,它们重叠,所以我需要添加集群命令,但我无法让它工作。我的代码在下面

<script>
$(document).ready(function() {

您使用的是哪个版本的 MC?因为 2.0.x 版本具有以下构造语法:

var markerCluster = new MarkerClusterer(map, opt_markers, opt_options);

尝试这个:

var markerCluster = new MarkerClusterer(map);
markerCluster.addMarker(marker1);
...
markerCluster.addMarker(marker9);

或者,将您的标记保留在数组中,将其添加到您的代码顶部:

var markers = [];

声明每个标记后,将其添加到该数组中:

markers.push(markerN);

并一次将它们全部添加到集群中:

markerCluster.addMarkers(markers);
