点击谷歌地图后获取经纬度 Get Latitude and Longitude (Location Coordinates) using Google Maps
n this short code snippet article I will explain how to get the Geographical position coordinates of a location i.e. Latitude and Longitude when user clicks anywhere on Google Maps using the Google Maps V3 OnClick event handler.
In the below Google Map implementation, I have assigned an event handler to the Google Map within which the geographical position coordinates of a location i.e. Latitude and Longitude are captured and displayed using JavaScript alert message box.
