Uncaught ReferenceError: MarkerWithLabel is not defined
I thought MarkerWithLabel is the built-in of the google maps api. But it doens't work.
我认为 MarkerWithLabel 是 google maps api 的内置。但它不起作用。
回答by geocodezip
MarkerWithLabel is not part of the Google Maps Javascript API v3, it is in a third party library MarkerWithLabel.
MarkerWithLabel 不是Google Maps Javascript API v3 的一部分，它位于第三方库MarkerWithLabel 中。
One indication is that if it was part of the API it would be google.maps.MarkerWithLabel.
一个迹象是，如果它是 API 的一部分，它将是 google.maps.MarkerWithLabel。
