多邊形陣列不會在谷歌地圖API的工作

我有一個在谷歌地圖API陣列畫多邊形的代碼，但它並沒有通過這個緯度經度這裏工作多邊形陣列不會在谷歌地圖API的工作

     //by now you should have the polylines array filled with arrays that hold the coordinates of the polylines of the multipolyline

此代碼的工作this 但不起作用我的經緯度

的高鐵總站在你的例子有額外的支撐，這就是爲什麼解析部分失敗對於一些LatLngs – 2014-09-01 14:25:18

這將有助於如果你比「不起作用」更具體。告訴我們出了什麼問題。 – skrrgwasme 2014-09-20 01:07:09

您在WKT表示中反轉了經度和緯度。這應該是「經度緯度」：

更改此：

var mps = ["MULTIPOLYGON(((25 80.1,18.4 66.1,32.3 64.7,25.7 80.1)),(25.1 80.5,18.8 66.1,32.9 64.2,25.1 80.5))"];

要：

var mps = ["MULTIPOLYGON(((80.1 25,66.1 18.4,64.7 32.3,80.1 25.7),(80.5 25.1,66.1 18.8,64.2 32.9,80.5 25.1)))"];

Working fiddle
