问题描述
有没有办法限制淘汰世界的优势?在这张照片上,棕色是世界,灰色是空虚。我想让它无法像这样平息。
Is there a way to limit panning out of the world's edge? On this picture, brown is the world, grey is emptiness. I want to make it impossible to pan like this.
推荐答案
Leaflet允许你用<$控制地图抵抗被拖出边界的程度c $ c> maxBoundsViscosity 选项(值:0到1)。将其设置为最大值会禁用完全拖出边界。
Leaflet allows you to control how much the map resists being dragged out of bounds with the maxBoundsViscosity
option (value: 0 to 1). Setting it to maximum disables dragging out of bounds entirely.
var map = new L.Map('map', {
center: bounds.getCenter(),
zoom: 5,
layers: [osm],
maxBounds: bounds,
maxBoundsViscosity: 1.0
});
This feature is available in 1.0.0. The relevant pull request includes a working example:
var osmUrl = 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
osmAttrib = '© <a href="http://openstreetmap.org/copyright">OpenStreetMap</a> contributors',
osm1 = L.tileLayer(osmUrl, {
maxZoom: 18,
attribution: osmAttrib
}),
osm2 = L.tileLayer(osmUrl, {
maxZoom: 18,
attribution: osmAttrib
}),
bounds = new L.LatLngBounds(new L.LatLng(49.5, -11.3), new L.LatLng(61.2, 2.5));
var map1 = new L.Map('map1', {
center: bounds.getCenter(),
zoom: 5,
layers: [osm1],
maxBounds: bounds,
maxBoundsViscosity: 0.75
});
var map2 = new L.Map('map2', {
center: bounds.getCenter(),
zoom: 5,
layers: [osm2],
maxBounds: bounds,
maxBoundsViscosity: 1.0
});
var latlngs = L.rectangle(bounds).getLatLngs();
L.polyline(latlngs[0].concat(latlngs[0][0])).addTo(map1);
L.polyline(latlngs[0].concat(latlngs[0][0])).addTo(map2);
