google-maps - 细节级别调整（Google Maps API）

Question

是否有可能更改地图上不同缩放级别上显示的名称（标签）/边界的方式？

例如，我有 17 个缩放级别。我想仅在缩放级别 10 上开始显示详细信息（国家名称）。

换句话说：地图上的详细程度如何与缩放级别相关联以及如何对其进行调整？

function show_map(lat, lng) {
    var labelsOff = [{
        featureType: "administrative",
        elementType: "labels",
        stylers: [{
            visibility: "off"
        }]
    }, {
        featureType: "poi",
        elementType: "labels",
        stylers: [{
            visibility: "off"
        }]
    }, {
        featureType: "water",
        elementType: "labels",
        stylers: [{
            visibility: "off"
        }]
    }, {
        featureType: "road",
        elementType: "labels",
        stylers: [{
            visibility: "off"
        }]
    }];

    var labelsOn = [{
        featureType: "administrative",
        elementType: "labels",
        stylers: [{
            visibility: "on"
        }]
    }, {
        featureType: "poi",
        elementType: "labels",
        stylers: [{
            visibility: "on"
        }]
    }, {
        featureType: "water",
        elementType: "labels",
        stylers: [{
            visibility: "on"
        }]
    }, {
        featureType: "road",
        elementType: "labels",
        stylers: [{
            visibility: "on"
        }]
    }];

    latlng = new google.maps.LatLng(51.477391, -0.000853);
    myOptions = {
        zoom: 3,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map"), myOptions);
    map.setOptions({
        styles: labelsOff
    });

    google.maps.event.addListener(map, 'zoom_changed', function () {
        google.maps.event.addListenerOnce(map, 'tilesloaded', function () {
            if (map.getZoom() >= 10) {
                map.setOptions({
                    styles: labelsOn
                });
            } else {
                map.setOptions({
                    styles: labelsOff
                });
            }
        });
    });

}


show_map();

希望这就是你要找的。显然你可以编辑这些特征类型来隐藏不同的东西。

对不起，不得不编辑。忘了小提琴！
