您好希望这个网站上的所有专家都能提出一个简单的问题...我上面的页面工作正常，但我真的很喜欢它，如果黑色和白色地图kml图层将开始强制用户切换它。我有很多关于这张地图的事情，我很遗憾所有的代码。如果您转到我的站点并单击图层按钮，则第一个选项是BW MAP切换。我只想让页面加载BW MAP kml图层。我已经尝试了我在这个网站上找到的几个选项，但仍然只是试错而没有运气....我认为这是你可能需要帮助的大部分代码......谢谢。

编辑 - 可能更容易“不接受”地理定位，因此您可以看到我所处的位置。地图将在没有启用的区域加载....

如果您在创建图层时不想显示图层，请不要将图层添加到地图中（删除{map: map}图标（并且不要将复选框设置为＆ ＃34;检查＆＃34;。）
