waypoints: waypoints,
reverseWaypoints: false,
lineOptions: {
styles: [{color: 'red', opacity: 1, weight: 3}]
},
geocoder: L.Control.Geocoder.nominatim({
serviceUrl: 'http://localhost:8084/'
}),
createMarker: function(i, wp, nWps) {
console.log(wp)
let custom_icon = L.divIcon({
iconSize: [100, 20],
popupAnchor: [-30, -18],
shadowUrl: '',
html: '<div class="notification '+wp.name+'" data-pathid="'+(i+1)+'" style="color: #000;background-color: transparent;"><img src="img/blue.png"><span class="city-name">' + latlng[i].name + '</span></div>'
})
marker = L.marker(
[wp.latLng.lat, wp.latLng.lng],
{
icon: custom_icon
})
.bindPopup(latlng[i].name)
.openPopup()
.addTo(map);
// marker.on('click', onMarkerClick);
