你可能想看看下面的例子。首先它嘗試地理編碼address1
。如果成功,它會嘗試對地址address2
進行地理編碼。如果兩個成功,它繪出了測地折線在兩個座標之間,以及兩個標誌:

如果你有你的地圖上十億個像我這樣做。這看起來很酷:'var color ='#'+(Math.random()* 0xFFFFFF << 0).toString(16); \t \t \t \t \t \t新google.maps.Polyline({ \t \t \t \t路徑: \t \t \t \t initialLocation, \t \t \t \t current_point \t \t \t \t], \t \t \t \t則strokeColor:顏色, \t \t \t \t短程線:真, \t \t \t \t圖:圖 \t \t \t \t});' – 2012-10-25 18:44:16
