谷歌地圖API v3端口

我想將我的谷歌api v2移植到v3，但它不起作用....我得到「折線未定義」錯誤...：/舊的折線是GPolyline和新的是確實沒有定義谷歌地圖API v3端口

Polyline新google.maps.Polyline。在這裏您可以使用它：

encodedPolyline = Polyline.fromEncoded({

3版不包括fromEncoded() —看來，你需要使用geometry庫（這需要單獨明確加載）和

encodedPolyline.setPath(
    google.maps.geometry.encoding.decodePath(mapElements[i]['pol']) 
    );

[爲了清晰起見，在分開的線上分開]
