我使用这个示例 示例来创建我的代码以从 lat 中查找地址。并且很长。坐标。

问题是,同样使用正确的坐标,我找到的是邮政编码而不是地址。相反,在示例中,它可以找到地址。我也尝试使用逆向方法。我使用了我在地址中找到的坐标,但他们给了我邮政编码,而不是地址。我哪里错了?

我的代码如下:

以下是在 JSFIDDLE 添加的 DEMO 的完整工作示例:

<script type="text/javascript">
    function showAddress() {
        var map,marker,infoWindow, geocoder;
        var markerPoint = new google.maps.LatLng(12.397,78.644);
        var mapOptions = {
            center: new google.maps.LatLng(12.397,73.644),
            zoom:5,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map_canvas"),
            mapOptions);
        google.maps.event.addListener(map,'click',function(e) {
            getAddress(e.latLng);
        });


    function getAddress(latLng) { 

        if(!geocoder) {
            geocoder = new google.maps.Geocoder();
        }
        var geocoderRequest = {
            latLng:latLng
        }
        geocoder.geocode(geocoderRequest, function(results, status) {
            if(!infoWindow) {
                infoWindow = new google.maps.InfoWindow();
            }
            infoWindow.setPosition(latLng);
            var content = "<h2>Position :" +latLng.toUrlValue()+ "</h2>"
            if(status == google.maps.GeocoderStatus.OK) {
                for(var i =0;i <results.length; i++) {
                    if(results[0].formatted_address) { 
                        content += i + ". " +results[i].formatted_address + "<br />";

                    }
                }

            }
            else {
                content += "<p>Either you clicked on Ocean or a Politically disputed Area. Status = " + status + "</p>"
            }
            infoWindow.setContent(content);
            infoWindow.open(map)
        });
    }
    }
</script>

示范

单击地图将生成一个信息窗口,此信息窗口将根据反向地理编码显示所单击地点的地址。
