Question

I have searched similar questions and have not found an answer for my case. I would like to work with 3 leaflet maps, each one will have different content. Two problems arise:

Only the first one is displayed.
Scale and zoom controls are only displayed in the third.

I attached a jsfiddle in case you can help.

const mapbox = L.tileLayer(mapboxUrl, {
    id: 'mapbox.streets',
    token: mapboxToken,
    attribution: mapboxAttribution,
});

mapbox.addTo(mapOne);
mapbox.addTo(mapTwo);
mapbox.addTo(mapThree);

Thank you :)

创建可重用的mapbox函数并每次传递地图实例：

const mapbox = (map) => {
  return L.tileLayer(mapboxUrl, {
    id: 'mapbox.streets',
    token: mapboxToken,
    attribution: mapboxAttribution,
  }).addTo(map)
};

[mapOne, mapTwo, mapThree].forEach(mapInstance => mapbox(mapInstance));

const mapOne = L.map('mapOne', {
  zoomControl: false,
  maxZoom: 18,
  minZoom: 6,
}).setView([40, -4], 6);

const mapTwo = L.map('mapTwo', {
  zoomControl: false,
  maxZoom: 18,
  minZoom: 6,
}).setView([40, -4], 6);

const mapThree = L.map('mapThree', {
  zoomControl: false,
  maxZoom: 18,
  minZoom: 6,
}).setView([40, -4], 6);

// Add a tile layer to the map (Mapbox Streets tile layer)
const mapboxToken = 'pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpejY4NXVycTA2emYycXBndHRqcmZ3N3gifQ.rJcFIG214AriISLbB6B5aw';
const mapboxUrl = 'https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token={token}';
const mapboxAttribution = [
  'Map data &copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors,',
  '<a href="http://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>,',
  'Imagery © <a href="http://mapbox.com">Mapbox</a>',
].join(" ");

const mapbox = (map) => {
  return L.tileLayer(mapboxUrl, {
    id: 'mapbox.streets',
    token: mapboxToken,
    attribution: mapboxAttribution,
  }).addTo(map)
};

[mapOne, mapTwo, mapThree].forEach(mapInstance => mapbox(mapInstance));


// Add a zoom control to the map
const zoomControl = new L.Control.Zoom({
  position: 'topleft'
});
zoomControl.addTo(mapOne);
zoomControl.addTo(mapTwo);
zoomControl.addTo(mapThree);

// Add a scale
const scaleControl = L.control.scale({
  maxWidth: 200,
  metric: true,
  imperial: false,
  position: 'bottomright'
});
scaleControl.addTo(mapOne);
scaleControl.addTo(mapTwo);
scaleControl.addTo(mapThree);

// Add a fullscreen control to the map (plugin)
mapOne.addControl(new L.Control.Fullscreen());
mapTwo.addControl(new L.Control.Fullscreen());
mapThree.addControl(new L.Control.Fullscreen());

#mapOne,
#mapTwo,
#mapThree {
  width: 80%;
  height: 500px;
  margin-top: 10px;
}
