Question

当我根据此stackoverflow question将preserveViewport:true添加到kmlLayer选项时，Google地图开始抛出'未捕获的TypeError：无法读取属性'lat'为'错误'。

HTML：

<div id="map"></div>

的javascript：

function initialize() {
            var mapOptions = {
                scrollwheel: false,
                zoom: 11,
                center: google.maps.LatLng(41.875696,-87.624207),
                styles: [{"featureType":"administrative","elementType":"all","stylers":[{"visibility":"on"},{"saturation":-100},{"lightness":20}]},{"featureType":"road","elementType":"all","stylers":[{"visibility":"on"},{"saturation":-100},{"lightness":40}]},{"featureType":"water","elementType":"all","stylers":[{"visibility":"on"},{"saturation":-10},{"lightness":30}]},{"featureType":"landscape.man_made","elementType":"all","stylers":[{"visibility":"simplified"},{"saturation":-60},{"lightness":10}]},{"featureType":"landscape.natural","elementType":"all","stylers":[{"visibility":"simplified"},{"saturation":-60},{"lightness":60}]},{"featureType":"poi","elementType":"all","stylers":[{"visibility":"off"},{"saturation":-100},{"lightness":60}]},{"featureType":"transit","elementType":"all","stylers":[{"visibility":"off"},{"saturation":-100},{"lightness":60}]}],
                zoomControlOptions: {
                    style: google.maps.ZoomControlStyle.SMALL
                }
            }

            var map = new google.maps.Map(document.getElementById('map'), mapOptions);

            var ctaLayer = new google.maps.KmlLayer(
                'https://maps.google.com/maps/ms?msa=0&msid=209537462410499505635.0004d278fb32588bd6da3&ie=UTF8&t=h&ll=48.985492,18.191269&spn=0.27644,0.427604&output=kml',
                {
                    suppressInfoWindows: true,
                    map: map,
                    preserveViewport: true
                }
            );
            ctaLayer.setMap(map);
        }

        google.maps.event.addDomListener(window, 'load', initialize);

没关系，地图停止使用KML的中心并转到mapOptions，它是

center: google.maps.LatLng(41.875696,-87.624207),

必须将其更改为

center: new google.maps.LatLng(41.875696,-87.624207),

将“preserveViewport：true”添加到kmlLayer选项时，Google地图会引发错误
