我需要帮助更改每个 KML 图层的颜色和/或下面用于 Google Maps Api 的脚本的随机颜色。我将整个脚本附在下面。我想知道如何更改每个多边形的填充和边框并生成随机颜色。这是一个动态 SQL 脚本。任何帮助将不胜感激。谢谢。

最佳答案
您无法使用 Google Maps API v3 更改 KmlLayer 中多边形的颜色。您可以更改生成的 KML 以设置颜色。
关于jquery - Google Maps API KML 图层更改每个图层的颜色，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16368796/
