谷歌地图在拖动标记后获取新地址信息

Question

我已创建了一个自动完成表单，因此用户无需输入所有地址字段。在底部，我包含了他从autoComplete中选择的位置的地图和街道视图，但是在用户拖动标记后我想更新所有字段以显示更新的标记位置但我只能获得更新纬度/经度不是新的地名，城市，邮政编码等，请查看我的代码（我需要帮助的代码位于底部）并感谢您的帮助。

//autocomplete address functionality
    function initMap() {
        var input = document.getElementById('searchTextField');
        var autocomplete = new google.maps.places.Autocomplete(input);
        google.maps.event.addListener(autocomplete, 'place_changed', function () {
            var place = autocomplete.getPlace();
            //auto fill the address fields
            document.getElementById('city2').value = place.name;
            document.getElementById('cityLat').value = place.geometry.location.lat();
            document.getElementById('cityLng').value = place.geometry.location.lng();
            document.getElementById('city').value = (place.address_components[3].long_name);
            document.getElementById('state').value = (place.address_components[5].long_name);
            document.getElementById('zip').value = (place.address_components[7].short_name);
            loadMaps();
        });
    }
google.maps.event.addDomListener(window, 'load', initMap);
