堆栈溢出用户给了我一个上一个问题的答案 .

他为我的回答做了一个小提琴 . 他的小提琴完全符合我的要求,但出于某种原因,我不能让他的代码与我合作

这是小提琴http://jsfiddle.net/geocodezip/fnygnokw/6/?utm_source=website&utm_medium=embed&utm_campaign=fnygnokw

这是我的代码 . 我希望能够点击标记并让它显示我的数据库中的一些信息,这是他的代码能够完美地完成的 .

这是上一个问题的链接multiple markers on google maps from firebase database

如果有人能帮助我弄清楚他是如何做到的,我会非常感激 .
