我在这个问题上需要帮助,请

我正在尝试将Google Map 缩放级别设置为 15 ,但这会导致地图无法完全呈现,而是呈现为灰色区域

这是地图的截图,以明白我的意思

enter image description here

这是我的代码

<script type="text/javascript">
    var geocoder;
    var map;
    var markersArray = [];

    function initialize() {
        geocoder = new google.maps.Geocoder();

        var zoomLevel = 6;
        //(38.5923884129755, 31.0229229927063)39.86619, 35.44768
        var latlng = new google.maps.LatLng(38.5923884129755, 31.0229229927063);

        var mapOptions = {
            zoom: zoomLevel,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }

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

        google.maps.event.addListener(map, 'click', function(event) {
            addMarker(event.latLng);
        });

        var hdnZoom = $("input[id$='hdnZoom']")[0];
        var hdnLocation = $("input[id$='hdnLocation']")[0];
        if (hdnZoom && hdnLocation) {
            setMarker(hdnZoom.value, hdnLocation.value);
        }            
    }

    function setMarker(zoom, location) {

        if (zoom && zoom != '' && location && location != '') {

            var loc = location.split(",");
            var latlng = new google.maps.LatLng(loc[0].substring(1), loc[1].substring(0, (loc[1].length - 1)));
            if (latlng) {
                addMarker(latlng)
            }

            map.setZoom(parseInt(zoom)); //zoom = 15
        }
    }

    function addMarker(location) {
        clearOverlays();

        var hdnZoom = $("input[id$='hdnZoom']")[0];
        if (hdnZoom) {
            hdnZoom.value = map.getZoom();
        }

        var hdnLocation = $("input[id$='hdnLocation']")[0];
        if (hdnLocation) {
            hdnLocation.value = location;
        }

        marker = new google.maps.Marker({
            position: location,
            map: map
        });

        markersArray.push(marker);
    }

如果缩放级别小于或等于8,此代码可以正常工作。

未完全渲染的地图不是由缩放级别引起的,请检查您的latlng
