Original-markerIcon = leaflet/images/marker-icon-2x.png
current-markerIcon = leaflet/images/map-marker.png
I have many markers and I want to change marker icon of the current clicked marker.If I click again on another marker change all marker Icon to original marker and current marker with current Icon.
I also have label attached with each marker.
When I click on current Icon I want to change also the label of that marker or remove the label.
How can I achieve this ?
thank you.
Image with marker visible with original-markerIcon
EDIT-1
L.Icon.Change = L.Icon.Default.extend({
options: {
iconUrl: 'leaflet/images/map-marker.png',
iconSize: new L.Point(150, 75),
}
});
var changeIcon = new L.Icon.Change();
L.Icon.Original = L.Icon.Default.extend({
options: {
iconUrl: 'leaflet/images/marker-icon-2x.png',
iconSize: new L.Point(45, 81),
}
});
var originalIcon = new L.Icon.Original();
marker.on('click',function(e){
for(var i = 0 ; i < $scope.markers.length ; i++){
$scope.markers[i].setIcon(originalIcon);
}
})
// marker click event to show the center pano
$scope.markers[index].on('click',function(e){
$scope.markers[index].setIcon(changeIcon);
});
If i am not mistaking there is a function named as "eachLayer" in map. I think when you create a marker, leaflet gives an automatic ID for that. So you have to give that ID in "eachLayer" function. And when it finds appropriate marker, there should be a function "popupclose". To add it will be better if you show your code...!

I am working with mapbox markers and I have created multiple markers as follows:
var cord = [{lng:,lat:},{lng:,lat:}]
function createMarker(){
for(var i = 0; i < cord.length; i++){
var marker = new mapboxgl.Marker({})
.setLngLat([cord[i].lng, cord[i].lat])
.addTo(map);
}
}
I wanted each marker to detect the click but I am unable to figure out how to do it?
Is it possible to detect click on each marker ?
You can add a click event handler like this:
marker.element.addEventListener('click', event => alert('click'));
My function is supposed to display a marker over an existing icon (US Cities) when clicked/selected. The marker is an image file. Then when the user clicks on another icon, the previous marker should disappear.
It seems to work fine at first. The first marker is created when the icon is clicked. When the second icon is clicked, the marker is created and the original marker disappears. When a third icon is clicked, the marker does not appear. The console says "marker is not defined".
Here is my code:
map.on('click', 'usa_cities', function(highlightMarker) {
var markerCoordinates = highlightMarker.features[0].geometry.coordinates.slice();
var markerElement = document.createElement('div');
markerElement.id = 'marker';
// create the marker
new mapboxgl.Marker(markerElement)
.setLngLat(markerCoordinates)
.addTo(map);
map.on('click', 'usa_cities', function() {
marker.remove()
});
}),
Thank you
You don't need to create a new marker each time the user clicks. You can simply call marker.setLngLat(markerCoordinates).
I am using leaflet plugin to show the marker. When I click on the current marker the icon should change the current marker only.
Again when I click on another marker change that marker to new icon and keep all other marker icon original.
Like I have 2 marker Icon
1- original Icon which I am setting when showing the marker on map
2- new marker - I want this marker icon should be set when click on marker.Only current Marker Icon should be changed and keep all other Icon Original Icon.
you can try this.
When you click the marker1, its icon will change to the one you set.
let marker1 = L.marker([e.latitude, e.longitude], { icon: greenIcon }).on('click', ()=>{
marker1.setIcon(redIcon)
}).addTo(map)
Do you have a marker layer? If yes you could first create a new icon
var customIcon = L.Icon.extend({
options: {
iconSize: [40.4, 44],
iconAnchor: [20, 43],
popupAnchor: [0, -51]
}
});
var myCustomIcon = new CustomIcon({ iconUrl: '../images/marker.png' });
After that you should get clicked marker's index inside the Layer and update the icon like this:
markersLayer[markersIndex].setIcon(myCustomIcon);
How to add a custom icon in mapbox?
var map = L.mapbox.map('map', 'mapbox.streets').setView([0, 0], 1);
var geojson = { type: 'LineString', coordinates: value};
var start = value[0];
var end = value[value.length-1];
geojson.coordinates.push((start,end).slice());
// Add this generated geojson object to the map.
L.geoJson(geojson).addTo(map);
// Create a marker and add it to the map.
var marker = L.marker(end, {
icon: L.mapbox.marker.icon({
"iconUrl": "https://www.mapbox.com/mapbox.js/assets/images/astronaut2.png"
})
}).addTo(map);
});
I can't able to add a custom icon in above code. Please help me..
Thanks.
First you will have to create a var, for example 'myIcon', then simply replace the iconUrl with a path that specifies the custom marker you want to use.
You can use the iconSize option to specify the size of your marker
You can use the iconAnchor option to specify which part of your masker should be placed on the latlng.
myIcon=L.icon({
iconUrl:'img/custom-marker.png',
iconSize: [25,30]
});
Then create the marker, set the lat lng where you want your marker to be placed. And specify the icon you want to use.
var Marker = new L.Marker ( latlng, {icon:myIcon});
Finally add your market to the map:
map.addlayer(Marker);
I've an issue with the leaflet openPopup method.
showMap = function(elements) {
var jsonp = 'http://a.tiles.mapbox.com/v3/blahblahblah.jsonp';
var m = new L.Map("my_map").setView(new L.LatLng(51.5, -0.09), 15);
var geojsonLayer = new L.GeoJSON();
var PlaceIcon = L.Icon.extend({
iconSize: new L.Point(25, 41),
shadowSize: new L.Point(40, 35),
popupAnchor: new L.Point(0, -30)
});
var icon = new PlaceIcon(__HOME__ + '/images/leaflet/marker.png');
var marker;
for (var i = 0; i < elements.length; i++) {
var address = $("<div/>").html(elements[i].address).text();
var latlng = new L.LatLng(elements[i].latitude, elements[i].longitude);
marker = new L.Marker(latlng, {icon: icon}).bindPopup(address);
if (i == 0) {
marker.openPopup();
}
m.addLayer(geojsonLayer).addLayer(marker);
}
// Get metadata about the map from MapBox
wax.tilejson(jsonp, function(tilejson) {
m.addLayer(new wax.leaf.connector(tilejson));
});
}
When I click on a marker I have the popup open. But I would like to have the first popup open when the map is loaded. (and open other popups on markers click)
AnNy ideas ?
Put openPopup call after you add the marker to the map and you should be fine.
I'm assuming that when you click on a marker you see the popup but you're not getting the popup of the first marker to show automatically when the map is loaded?
First, it doesn't look like you're actually using GeoJSON so a GeoJSON layer isn't necessary (you can just use a FeatureLayer) but that shouldn't cause any issues. Whatever layer group you use you should only be adding it to the map once and then adding all child layers to the LayerGroup. You're currently adding the geojsonLayer multiple times in your "for" loop which you don't want to do.
Second, you have to call marker.openPopup() after the marker is added to the map.
Try changing your code around to looks something like this:
var layerGroup = new L.FeatureGroup();
layerGroup.addTo( m );
for (var i = 0; i < elements.length; i++) {
var address = $("<div/>").html(elements[i].address).text();
var latlng = new L.LatLng(elements[i].latitude, elements[i].longitude);
marker = new L.Marker(latlng, {icon: icon}).bindPopup(address);
//You don't add the marker directly to the map. The layerGroup has already
//been added to the map so it will take care of adding the marker to the map
layerGroup.addLayer( marker );
if (i == 0) {
marker.openPopup();
}
}
I had this issue and fixed it with adding a timeout right after I added the marker on the map.
marker.addTo(this.map).bindPopup('Info');
setTimeout(() => {
marker.openPopup();
}, 500);
I don't know why but on some page, I need to apply timeout. In any case it's my workaround, hope this works for some of you too.
First add your map then put openPopup():
L.marker([lat, long]).bindPopup('Your message').addTo(map).openPopup();
