Google Maps API: markerwithlabel.js - Uncaught ReferenceError: google is not defined

问题:

I have read the docs and examples, but I it seems I cannot solve the initialization error ("Uncaught ReferenceError: google is not defined" + Uncaught ReferenceError: homeLatLng is not defined) when trying to include markerwithlabel.js file and it's reminds me to the "you cannot load something before the map is done" prob.

What can I do?

What was tried:

回答1:

markerwithlabel.js requires a already loaded maps-API.

When you load the maps-API asynchronously(as you do in your code), there is no guarantee that the maps-API is loaded when markerwithlabel.js will be loaded.

solution: load the maps-API synchronously
