Question

我正在尝试创建一个包含多个kml图层的地图，这些图层可以通过Google地方搜索进行切换，但一直未成功。这样做的目的是能够搜索地址或交叉点并确定用于调度中心的火灾或医疗呼叫的正确响应装置，其中搜索偏向正确的县。我的基本地图只有一个图层工作here，但我无法正确地将kml图层切换与Google地方搜索集成。我在使用地理编码函数geocodezip时收到了here的一些好的输入，但是我无法将其偏向正确的位置或包含预测搜索完成。我也喜欢我的原始地图将缩放并以搜索到的地址为中心并希望保持该功能的方式。不可否认，我对这方面的能力非常缺乏，我所做的一切都是简单地复制和修改其他人发布的工作示例，但我没有发现任何包含谷歌地方搜索和kml图层的工作示例切换。这就是我到目前为止所拥有的。任何帮助实现这一目标的人都将非常感激。
