我打算在我的應用程序之一中使用谷歌地圖「containsLocation()」API。文檔鏈接是 - https://goo.gl/4BFHCz谷歌地圖錯誤 - a.lng不是函數
我遵循相同的示例。這是我的代碼。

如果您看到我創建了一個curPosition
變量,它包含latLng數據。我的問題在這裏只要var curPosition = e.latLng;
它工作正常,但是,當我將其更改爲var curPosition = {"lat":12.9629277,"lng":77.7178972};
它開始顯示錯誤"Uncaught TypeError: a.lng is not a function"
。
無法理解爲什麼會發生這種情況?任何線索......?
問候
可能有助於張貼你在那裏有控制檯日誌。尤其是JSON.stringify(e.latLng) – user2263572
嘗試傳遞** google.maps.LatLng **對象:'var curPosition = new google.maps.LatLng(12.9629277,77.7178972);' –
