谷歌地图API-获取信息窗口打开时，点击一个圆圈
Google Maps API - Get info window to open when clicking a circle?
我拼命想得到一个带圆圈的谷歌地图，点击它可以打开一个信息窗口。这似乎真的不是一个复杂的问题，但在网上搜索似乎是不可能的，但我想知道这些帖子是否是旧的，现在是可能的。
我想做什么我正在尝试一个谷歌地图（HTML代码，我可以在SharePoint上"托管"），在不同的位置有圆圈（到目前为止这一点还可以），我可以单击圆圈打开一个信息窗口，其中包含该位置的人员列表。
到目前为止我做了什么我一直在看谷歌地图javascript API页面，并成功地使用这个例子制作了一个带有圆圈的地图https://developers.google.com/maps/documentation/javascript/examples/circle-simple
我还试着在地图的中心放一个带有信息窗口的标记，虽然不太理想，但仍然可以接受，但这没有奏效。我只是简单地剪切了javascript中做标记的部分，页面就不会加载了。
我的背景很遗憾，我对Javascript一无所知。我对HTML略知一二，但我肯定不是技术背景，我只是想要一个看起来不错又能用的地图。我真的可以成为一个角色，但我不知道javascript的意思。
