问题描述

我正在尝试使用一些特定的参数来加载谷歌地图。我明白问题很可能是initMap函数需要全局声明。
然而，我不知道如何，即使在搜索了一些StackOverflow后类似的问题。

I am trying to load a google map with some specific parmeters. I understand the problem is most likely that the initMap function needs to be declared globally. However, I have no idea how, even after searching a number of StackOverflow post with similar problems.
