Question

您好我想知道Geocoder是否还在工作？当我初始化新的google.maps.geocoder（）时似乎没有反应;我的目的是从纬度和经度获取位置地址。

警报A和B正在运行。在警报C停止。

$('#btn').click(function initialize() {
            alert("A");
            var loc = {};
            alert("B");
            var geocoder = new google.maps.Geocoder();
            alert("C");
            if(google.loader.ClientLocation) {
                alert("D");
                loc.lat = google.loader.ClientLocation.latitude;
                loc.lng = google.loader.ClientLocation.longitude;

                var latlng = new google.maps.LatLng(loc.lat, loc.lng);
                geocoder.geocode({'latLng': latlng}, function(results, status) {
                    if(status == google.maps.GeocoderStatus.OK) {
                        alert(results[0]['formatted_address']);
                    };
                });
            }
        });

尝试从lat，lng获取地址。单击标记以显示地址。它可以替代你的工作。

Geocoder仍在为Javascript工作吗？
