I am currently using L.Routing.Control to get directions between 2 waypoints, draw and route with custom DivIcons and display the directions in a box. It works great however it will be used on mobile devices and when in portrait mode the directions take up most of the display. I would like to either just display the next 1 or 2 directions or get the value of the next direction and display it in a somewhere else.
The code I have to load and display it is :
myroutewithout = L.Routing.control({
waypoints: [
L.latLng(window.my_lat, window.my_lng),
L.latLng(window.job_p_lat, window.job_p_lng)
],show: true, units: 'imperial',
router: L.Routing.mapbox('KEY-HERE'),
createMarker: function(i, wp, nWps) {
if (i === 0 || i === nWps + 1) {
// here change the starting and ending icons
return mymarker = L.marker(wp.latLng, {
icon: window.operatorIcon
});
} else {
// here change all the others
return job_start = L.marker(wp.latLng, {
icon: window.jobIcon
});
}
}
}).addTo(map);
And the image of it running in both portrait and landscape

I am interested in showing the tooltip only for a specific zoom range (>=12) at any time. With the help of this other article I could manage to almost get there but I still have the problem that the tooltip come to appear when I activate the layer in my OverlayMaps-menu, disregarding the current zoom level.
In my leaflet map I have implemented a OverlayMaps-menu, in which almost all layers are deactivated from the start. For one of these deactivated layers, my aim is to show the tooltips for all features only from a zoom level of 12 or bigger. The code is as follows:
Declaration of the variable from a geoJSON object:
var vibro_offshore = L.geoJson (vbc_offshore, {
pointToLayer: function (feature, latlng) {
return new L.Circle (latlng, {
color:'#a13c02',
})
},
onEachFeature: enCadaVBC
});
In the onEachFeature function, beside some other code regarding popup, I also have defined the tooltips:
function enCadaVBC (feature, layer) {
//declaramos un tooltip
var tooltip = L.tooltip({
content: feature.properties.Location,
permanent: true,
direction:'right',
className:'tooltip'
});
//introducimos un tooltip
layer.bindTooltip(tooltip);
Finally, I have managed to govern the visibility of the tooltips depending on the zoom level with the code suggested in the article referred above:
var lastZoom;
map.on('zoomend', function() {
var zoom = map.getZoom();
console.log(zoom);
if (zoom < 12 && (!lastZoom || lastZoom >= 12)) {
map.eachLayer(function(l) {
if (l.getTooltip) {
var toolTip = l.getTooltip();
if (toolTip) {
this.map.closeTooltip(toolTip);
}
}
});
} else if (zoom >= 12 && (!lastZoom || lastZoom < 12)) {
map.eachLayer(function(l) {
if (l.getTooltip) {
var toolTip = l.getTooltip();
if (toolTip) {
console.log(toolTip);
this.map.addLayer(toolTip);
}
}
});
}
lastZoom = zoom;
})
All this works pretty good, but when I activate the layer via mouseclick on the OverlayMaps-menu, lets say when the zoom level is 9, all the tooltips suddenly appear. I want to avoid this.
I have tried to add a closeTooltip() command right after the bindTooltip-command, but this hasnt have any effect. A consol.log for Is Tooltipopen leads to an undefined...(?)
I also tried to relocate the layer.bindTooltip command into the if-loop, but here I do get some other error related to Mercator projection and latlng, which I do not really understand...
I'm working on Mapbox Studio Tutorial and practicing adding interactivity on POIs on map.
https://docs.mapbox.com/help/tutorials/add-points-pt-3/
map.on('click', (event) => {
// If the user clicked on one of your markers, get its information.
const features = map.queryRenderedFeatures(event.point, {
layers: ['layer1',"layer2","layer3"]
});
if (!features.length) {
return;
}
const feature = features[0];
/*
Create a popup, specify its options
and properties, and add it to the map.
*/
const popup = new mapboxgl.Popup({ offset: [0, -15] })
.setLngLat(feature.geometry.coordinates)
.setHTML(
`<h3>${feature.properties.title}</h3><p>${feature.properties.description}</p>`
)
.addTo(map);
});
The error I get is that the title of POIs from layer2 and layer3 is shown as "undefined" while layer1's title can be shown when clicking it on the map.
I think "undefined" comes because the title is not stored in the feature property but have no clear idea how to do that correctly.
I tried some codes I got from the internet such as below:
if (features.length > 0) {
// Loop feature and concatenate property as HTML strings
let propertiesHTML = '';
features.forEach(feature => {
Object.entries(feature.properties).forEach(([key, value]) => {
propertiesHTML += `<p><strong>${key}:</strong> ${value}</p>`;
});
});
// Create and add a popup
const popup = new mapboxgl.Popup({ offset: [0, -15] })
.setLngLat(features[0].geometry.coordinates)
.setHTML(propertiesHTML)
.addTo(map);
With code at least map is shown, but there is no interactive popup shown when I click it.
I am using leaflet and routing.control to show a route. I have it working fine, but I would like one of the markers to move with the users location using watch.position. But for now I a just trying to move the marker when I click a button. Again this works fine but when the marker moves I would like the route to update automatically. Its possible if you drag the marker so surely its possible when marker is moved in a different way? I can it if I remove the control and add a new one but this flickers too much. Any advice?
The code for the routing.control is
myroute = L.Routing.control({
waypoints: [
L.latLng(window.my_lat, window.my_lng),
L.latLng(window.job_p_lat, window.job_p_lng)
],show: true, units: 'imperial',
router: L.Routing.mapbox('API KEY HERE'),
createMarker: function(i, wp, nWps) {
if (i === 0 || i === nWps + 1) {
return mymarker = L.marker(wp.latLng, {
icon: redIcon
});
} else {
return job_start = L.marker(wp.latLng, {
icon: greenIcon
});
}
}
}).addTo(map);
and the code for moving the marker is
function movemarker() {
var lat = "52.410490";
var lng = "-1.575950";
var newLatLng = new L.LatLng(lat, lng);
mymarker.setLatLng(newLatLng);
// I assume I call something here?
}
Sorted, I did it with this, which removes first point and replaces it with new data
myroutewithout.spliceWaypoints(0, 1, newLatLng);
I build a simple js app:
var markers = L.markerClusterGroup({
spiderfyOnMaxZoom: true,
showCoverageOnHover: false,
zoomToBoundsOnClick: true,
removeOutsideVisibleBounds:true
});
for (var i = 0; i < randomGeoPoints.length; i++) {
var a = randomGeoPoints[i];
var title = "pippo";
var marker = L.marker(new L.LatLng(a[0], a[1]), { title: title,icon:lightIcon });
marker.bindPopup(title);
markers.addLayer(marker);
}
map.addLayer(markers);
With these two
and a demo
When I exit full screen mode my cluster points layer disappears. But when I return the layer is there.
I'm using Safari desktop browser, in Safari mobile (iPad) it does not happen.
I test with no cluster but with simple points layer and it's OK.
The Plunker demo instead works.
Are there any bugs about this ?
I just starting to learn about Leaflet.js for my upcoming project.
What i am trying to accomplish:
I need to make a list of marker which displayed on the map, and when the list item is being hovered (or mouseover) it will show where the position on the map (for single marker, it should change its color. For Clustered marker, it should display Coverage Line like how it behave when we hover it.. and perhaps change its color too if possible).
The map should not be changed as well as the zoom level, to put it simply, i need to highlight the marker/ Cluster on the map.
What i have accomplished now : I am able to do it on Single Marker.
what i super frustrated about : I failed to find a way to make it happen on Clustered Marker.
I use global var object to store any created marker.
function updateMapMarkerResult(data) {
markers.clearLayers();
for (var i = 0; i < data.length; i++) {
var a = data[i];
var myIcon = L.divIcon({
className: 'prop-div-icon',
html: a.Description
});
var marker = L.marker(new L.LatLng(a.Latitude, a.Longitude), {
icon: myIcon
}, {
title: a.Name
});
marker.bindPopup('<div><div class="row"><h5>Name : ' + a.Name + '</h5></div><div class="row">Lat : ' + a.Latitude + '</div><div class="row">Lng : ' + a.Longitude + '</div>' + '</div>');
marker.on('mouseover', function(e) {
if (this._icon != null) {
this._icon.classList.remove("prop-div-icon");
this._icon.classList.add("prop-div-icon-shadow");
}
});
marker.on('mouseout', function(e) {
if (this._icon != null) {
this._icon.classList.remove("prop-div-icon-shadow");
this._icon.classList.add("prop-div-icon");
}
});
markersRef[a.LocId] = marker; // <-- Store Reference
markers.addLayer(marker);
updateMapListResult(a, i + 1);
}
map.addLayer(markers);
}
But i don't know which object or property to get the Clustered Marker reference.
And i trigger the marker event by my global variable (which only works on single marker).
...
li.addEventListener("mouseover", function(e) {
jQuery(this).addClass("btn-info");
markersRef[this.getAttribute('marker')].fire('mouseover'); // --> Trigger Marker Event "mouseover"
// TODO : Trigger ClusteredMarker Event "mouseover"
});
...
This is my current https://jsfiddle.net/oryza_anggara/2gze75L6/, any lead could be a very big help. Thank you.
Note: the only js lib i'm familiar is JQuery, i have no knowledge for others such as Angular.js
You are probably looking for markers.getVisibleParent(marker) method, to retrieve the containing cluster in case your marker is clustered.
Unfortunately, it is then not enough to fire your event on that cluster. The coverage display functionality is set on the Cluster Group, not on its individual clusters. Therefore you need to fire your event on that group:
function _fireEventOnMarkerOrVisibleParentCluster(marker, eventName) {
var visibleLayer = markers.getVisibleParent(marker);
if (visibleLayer instanceof L.MarkerCluster) {
// In case the marker is hidden in a cluster, have the clusterGroup
// show the regular coverage polygon.
markers.fire(eventName, {
layer: visibleLayer
});
} else {
marker.fire(eventName);
}
}
var marker = markersRef[this.getAttribute('marker')];
_fireEventOnMarkerOrVisibleParentCluster(marker, 'mouseover');
Updated JSFiddle: https://jsfiddle.net/2gze75L6/5/
That being said, I think another interesting UI, instead of showing the regular coverage polygon that you get when "manually" hovering a cluster, would be to spiderfy the cluster and highlight your marker. Not very easy to implement, but the result seems nice to me. Here is a quick try, it would probably need more work to make it bullet proof:
Demo: https://jsfiddle.net/2gze75L6/6/
function _fireEventOnMarkerOrVisibleParentCluster(marker, eventName) {
if (eventName === 'mouseover') {
var visibleLayer = markers.getVisibleParent(marker);
if (visibleLayer instanceof L.MarkerCluster) {
// We want to show a marker that is currently hidden in a cluster.
// Make sure it will get highlighted once revealed.
markers.once('spiderfied', function() {
marker.fire(eventName);
});
// Now spiderfy its containing cluster to reveal it.
// This will automatically unspiderfy other clusters.
visibleLayer.spiderfy();
} else {
// The marker is already visible, unspiderfy other clusters if
// they do not contain the marker.
_unspiderfyPreviousClusterIfNotParentOf(marker);
marker.fire(eventName);
}
} else {
// For mouseout, marker should be unclustered already, unless
// the next mouseover happened before?
marker.fire(eventName);
}
}
function _unspiderfyPreviousClusterIfNotParentOf(marker) {
// Check if there is a currently spiderfied cluster.
// If so and it does not contain the marker, unspiderfy it.
var spiderfiedCluster = markers._spiderfied;
if (
spiderfiedCluster
&& !_clusterContainsMarker(spiderfiedCluster, marker)
) {
spiderfiedCluster.unspiderfy();
}
}
function _clusterContainsMarker(cluster, marker) {
var currentLayer = marker;
while (currentLayer && currentLayer !== cluster) {
currentLayer = currentLayer.__parent;
}
// Say if we found a cluster or nothing.
return !!currentLayer;
}
