缩放以适合Mapbox或Leaflet中的所有标记

如何在 MapboxLeaflet 中设置视图以查看 Map 上的所有标记?像Google Maps API一样 bounds

例如:

var latlngbounds = new google.maps.LatLngBounds();
for (var i = 0; i < latlng.length; i++) {
  latlngbounds.extend(latlng[i]);
}
map.fitBounds(latlngbounds);

var group = new L.featureGroup([marker1, marker2, marker3]);

 map.fitBounds(group.getBounds());

有关详细信息,请参阅here .

“答案”对我来说不起作用 . 所以这就是我最终做的事情:

////var group = new L.featureGroup(markerArray);//getting 'getBounds() not a function error.
////map.fitBounds(group.getBounds());
var bounds = L.latLngBounds(markerArray);
map.fitBounds(bounds);//works!

var markerArray = [];
markerArray.push(L.marker([51.505, -0.09]));
...
var group = L.featureGroup(markerArray).addTo(map);
map.fitBounds(group.getBounds());

Leaflet也有LatLngBounds甚至具有扩展功能,就像谷歌 Map 一样 .

http://leafletjs.com/reference.html#latlngbounds

所以你可以简单地使用:

var latlngbounds = new L.latLngBounds();

其余的完全相同 .

对于Leaflet,我正在使用

map.setView(markersLayer.getBounds().getCenter());

您还可以找到FeatureGroup或所有featureGroup中的所有功能,看看它是如何工作的!

//Group1
m1=L.marker([7.11, -70.11]);
m2=L.marker([7.33, -70.33]);
m3=L.marker([7.55, -70.55]);
fg1=L.featureGroup([m1,m2,m3]);

//Group2
m4=L.marker([3.11, -75.11]);
m5=L.marker([3.33, -75.33]);
m6=L.marker([3.55, -75.55]);
fg2=L.featureGroup([m4,m5,m6]);

//BaseMap
baseLayer = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png');
var map = L.map('map', {
  center: [3, -70],
  zoom: 4,
  layers: [baseLayer, fg1, fg2]
});

//locate group 1
function LocateOne() {
    LocateAllFeatures(map, fg1);
}

function LocateAll() {
    LocateAllFeatures(map, [fg1,fg2]);
}

//Locate the features
function LocateAllFeatures(iobMap, iobFeatureGroup) {
		if(Array.isArray(iobFeatureGroup)){			
			var obBounds = L.latLngBounds();
			for (var i = 0; i < iobFeatureGroup.length; i++) {
				obBounds.extend(iobFeatureGroup[i].getBounds());
			}
			iobMap.fitBounds(obBounds);			
		} else {
			iobMap.fitBounds(iobFeatureGroup.getBounds());
		}
}
