添加一个标记点后，拖动该标记点后，如何获取此标记点的经度和纬度呢？

[强]

//拖动
var marker1 = new GMarker(point, {draggable: true});
GEvent.addListener(marker1, "dragstart", function() {
map.closeInfoWindow();
});
GEvent.addListener(marker1, "dragend", function() {
marker1.openInfoWindowHtml("Just bouncing along...");
});
map.addOverlay(marker1);

           var marker1 = new GMarker(point, {draggable: true});
        GEvent.addListener(marker1, "dragstart", function() {

//           map.closeInfoWindow();

        });
         GEvent.addListener(marker1, "dragend", function() {

//          marker1.openInfoWindowHtml("Just bouncing along...");
var LatLng=marker1.getLatLng();
alert(LatLng);
        });
        map.addOverlay(marker1);
