[原]解决百度地图多个Marker和InfoWindow时总是打开最后一个InfoWindow的问题

         在做项目的过程中，发现了在使用百度地图的过程中，加入多个Marker和多个InfoWindow的时候，多个Marker可以在地图上不同的坐标点显示出来，但是当点击不同的Marker的时候，显示的总是最后一个Marker对应的InfoWindow。至少直接写For循环是这个样子的。

于是乎我看到之前的代码是对应着写：Marker1,InfoWindow1, Marker2,InfoWindow2, Marker3,InfoWindow3。我的个天呀，如果是100个呢？那得有多少的代码呀？

下面的代码是在原代码的基础上修改的，肯定还有很大提升的空间。

         

我们取到的数据，也就是下面data中的数据:
