我需要一些帮助来确定将任何天气层代码放在自定义 Google 地图(API v3)的位置,任何输入将不胜感激:)
我们创建了一个自定义的 Google 地图,在上面我们有 2 个带有简单切换的 Fusion Table 图层。从开发人员文档以及我在此站点上找到的内容中,我可以看到我需要添加这段代码:
var weatherLayer = new google.maps.weather.WeatherLayer({
temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT
});
weatherLayer.setMap(map);
但我完全不知道在哪里放置它,因为每次我尝试添加它(现在 2 天)时,代码都会中断,并且在 F12 控制台窗口中显示一个带有各种错误的空白白页。
我们需要在哪里添加它,我们如何将它添加到切换?这是我们的工作:
