Javascript – Trigger click on leaflet marker

javascript, jquery, leaflet

I have a bunch of leaflet markers on the map. Each marker is held in array markers. The markers are created dynamically (during an ajax call).

var markers = [];..var marker = L.marker([, mar.lng], {  // the marker...}marker._leaflet_id =; // give the marker an id corresponding to the id of its corresponding divvar myHoverIcon = L.icon({  iconUrl: mar.imgUrl,  iconSize: [40, 40],  popupAnchor: [0, 0]});marker.on('click', function(e) {  alert('Marker clicked!');  marker.setIcon(myHoverIcon);});..markers.push(marker);

Each marker has an id corresponding to a particular div (stored in data-mess_id on the div). The plan is to change the marker's icon when its corresponding div in the feed is clicked on.

$('#feed').on('mouseover', '.message', function() {  var cssid = $(this).attr('data-mess_id').toString();  var baz = $.grep(markers, function(m) {    return (m._leaflet_id == cssid);  });  baz[0].trigger('click');   // doesn't work   alert(baz[0].getLatLng()); // does work  // this also does not work:  var myHoverIcon = L.icon({    iconUrl: baz[0].imgUrl,    iconSize: [40, 40],    popupAnchor: [0, 0]  });  baz[0].setIcon(myHoverIcon);});

It's all working fine except for the final bit. I just can't trigger a click event on the marker. I definitely have the correct marker because baz[0].getLatLng() is working. But baz[0].trigger('click') doesn't work.

I tried creating a new icon dynamically (myHoverIcon) but it doesn't work.

How do I trigger a click event on the marker?

Is there another way to change the marker icon?

Best Solution

To emulate a mouse click, you can use the fire method (inherited from on the marker :'click');

And a demo

var map ='map').setView([0, 0], 12);var icon = L.icon({  iconUrl: ''});var marker = L.marker([0, 0], {icon: icon})  .addTo(map);    var myHoverIcon = L.icon({  iconUrl: ''});    marker.on('click', function(e) {  marker.setIcon(myHoverIcon);});document.querySelector('button').addEventListener('click', function() {'click');});
