srcmini基本上, 要获取用户在Google Maps实例上单击的位置的坐标, 你要做的就是将事件侦听器附加到地图本身。从接收到的事件中, 使用两个方法提取包含一个对象的latLng属性, 这两个方法是：lat和lng, 它们将分别返回纬度和经度值：
// Add click listener on the map
google.maps.event.addListener(map, "click", function (event) {
var latLng = event.latLng;
// e.g Latitude: 7.135742728253103, Longitude: -73.11638207013567
alert("Latitude: " + latLng.lat() + ", Longitude: " + latLng.lng());
});完整文档中的以下实现显示了如何初始化Google Maps以及如何附加侦听器：
