这让我发疯。请参见《 Leaflet》教程,以向地图添加图层控件:
L.Icon.Default.imagePath = "Scripts/images";
var mapUrl = 'http://{s}.tile.openstreetmap.se/hydda/full/{z}/{x}/{y}.png';
var secondMap = 'http://{s}.tile.osm.org/{z}/{x}/{y}.png';
var littleton = L.marker([39.61, -105.02]).bindPopup('This is Littleton, CO.'),
denver = L.marker([39.74, -104.99]).bindPopup('This is Denver, CO.'),
aurora = L.marker([39.73, -104.8]).bindPopup('This is Aurora, CO.'),
golden = L.marker([39.77, -105.23]).bindPopup('This is Golden, CO.');
var cities = L.layerGroup([littleton, denver, aurora, golden]);
var grayscale = L.tileLayer(mapUrl, { id: mapUrl }),
streets = L.tileLayer(secondMap, { id: secondMap });
var map = L.map('map', {
center: [39.73, -104.99],
zoom: 10,
layers: [grayscale, cities]
});
var baseMaps = {
"Grayscale": grayscale,
"Streets": streets
};
var overlayMaps = {
"Cities": cities
};
L.control.layers(baseMaps, overlayMaps).addTo(map);
现在,如何使用removeLayer函数通过map.on('click')事件从控件中删除“ GrayScale”地图?该代码将是:
map.on('click', function(){
//remove GrayScale
});
您是否希望用户能够通过按钮删除灰度?还是要由于其他事件而将其动态删除?还是只希望地图开始时根本没有灰度层?

让我们说说最简单的解决方案:动态地影响事件。例如,map.on('click',function(){})。我将相应地编辑我的帖子。
