问题描述
我遇到标记重叠的问题，请不要投票，因为我没有受过很高的JavaScript教育。我也查看了在stackoverflow上提供的不同答案，但无法使用它们查找解决方案，请帮助！代码是抓住php和lat的基础上，我已经给了我只想列出所有的信息在同一个标记，而不是重叠标记的任何帮助将高度赞赏这里是代码：经纬度和长期
I am having issues with markers overlapping, please do not down vote as I am not highly schooled in javascript also I have looked at the different answers offered on stackoverflow but have not been able to use them to find a solution so please help! The code is grabbing php for lat and long based on static points I have given I would simply like to list all of the information in the same marker rather than have it overlap markers any help would be highly appreciated here is the code:

推荐答案
我已经找到了解决方案，帖子由@geocodezip，我仍然有一个小问题时，放大标记直接在另一个将保持聚集模式，我想实现infoWindow共享两个标记内容任何帮助将是可怕的，再次感谢geocodezip您的帖子！
I have found a solution through much searching and thanks to posts by @geocodezip , I am still having one small problem when zooming into the markers any marker thats directly on another will stay in clustered mode, I would like to achieve the infoWindow sharing both markers content any help would be awesome , thanks again geocodezip for your posts!
