更改特定Google地图集群的集群图标-markerclusterplus [英] Change cluster icon for a particular google map cluster - markerclusterplus
本文介绍了更改特定Google地图集群的集群图标-markerclusterplus的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
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，并限制了对它的进一步深入研究.在该特定级别，我们正在为用户打开信息框.
I would like to change the cluster icon (dynamically/for particular cluster) based on some particular condition. I am able to identify the condition and have restricted further drill-down on the same. At that particular level we are opening infobox for the user.
问题出在群集上，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.
The problem lies with cluster as I want to change the icon to something else. For the individual pins the icon is fine.
下面是我要实现的代码:
Below is the code that I am trying to implement:
<!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>

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帮助我识别以上逻辑并创建信息窗口.
The logic that I am trying to build is that if the cluster has identical pins beneath it (I would not like to drill down) then change the icon to anything else.
The function _getPinStatus helps me identify the above logic and creates the infowindow.
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
I also somehow could not manage to get the zoom change event - but this is rather a separate query
我尝试使用clearMarkers()函数，并通过在options_markerclusterer数组中提供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.
I tried with clearMarkers() function and remap the clusters by providing the image in options_markerclusterer array but it does replace the image on all underlying markers.
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.
I could not find details around setStyles and its implementation. Would it be feasible to push styles once the map is already plotted.
赞赏任何建议.
推荐答案
您可以在用于定义群集"图标样式的样式数组中添加其他样式:
You can add additional styles to the style array used to define the Cluster icon styles:
var mcStyles = markerCluster.getStyles();
mcStyles.push({
url: "http://www.geocodezip.com/mapIcons/markerclusterer/heart50.png",
width: 50,
height: 44,
anchorIcon: [44, 25],
textSize: 10,
textColor: "black",
textDecoration: "none",
fontStyle: "normal",
fontFamily: "Arial,sans-serif",
backgroundPosition: "0 0",
});
然后调整计算器"当您点击相同的图钉"时，返回适当的索引(在本例中为6)情况:
Then adjust the "calculator" to return the appropriate index (in this case 6) when you hit your "same pin" case:
markerCluster.setCalculator(function(markers, numStyles) {
var index = 0,
count = markers.length,
total = count;
while (total !== 0) {
//Create a new total by dividing by a set number
total = parseInt(total / 5, 10);
//Increase the index and move up to the next style
index++;
}
index = Math.min(index, numStyles);
samePin = _getPinStatus(markers);
if (samePin) {
return {
text: count + " (" + count + " Jobs)",
index: 6 // reference added style
};
} else {
return {
text: count,
index: index
};
}
});

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