问题描述
我想根据某些特定条件更改群集图标（动态/针对特定群集）。我能够确定情况，并限制了进一步的深入研究。在该特定级别，我们正在为用户打开信息框。
问题在于群集，因为我想将图标更改为其他名称。对于单个图钉，图标就可以了。
下面是我要实现的代码：
<!DOCTYPE html>
<html>
<head>
<style>
/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html,body {
height: 80%;
margin: 0;
padding: 0;
}
</style>
</head>
<body>

var gm_map;

var infoWindow = new google.maps.InfoWindow();
function initialize(searchMarkers = []) {
var marker,i;
if(searchMarkers.length == 0) {
clusterMarkers = [

我要构建的逻辑是，如果群集下面有相同的引脚（我不想向下钻取），则将图标更改为其他任何内容。
函数_getPinStatus可帮助我识别以上逻辑并创建信息窗口。
我也以某种方式无法获得zoom change事件-但这是一个单独的查询
我尝试使用clearMarkers()函数，并通过提供options_markerclusterer数组中的图像来重新映射群集，但是它确实替换了所有基础标记上的图像。
我找不到有关setStyles及其实现的详细信息。地图绘制完成后，推送样式是否可行。
赞赏任何建议。
