Javascript 谷歌地图API v3-我可以从Marker获取内容吗？

我创建了很多标记，但我认为在获得用于平均和设置信息窗口的内容后，单击内部是markerCluster上所有标记的平均值

每个标记都必须给他一个值。快照

我想抓取所有标记和平均值，并显示在信息窗口中。快照：

这是我的密码：

将自定义特性添加到包含其“值”的标记：

您的代码是什么样子的？将其添加到question@duncan我添加我的代码！天哪！谢谢你，这对我帮助很大！非常感谢你。编辑我的问题并回答我的问题！；）这晚了一年左右，但平均数计算错了。。它们应该是

（total/（allmarke.length））

，而不是

（total/（allmarke.length-1））

。修正错误永远不会太迟。更新了fiddle链接（在评论中没有注意到您的链接）和代码段。谢谢
