for a small project I am working on, I need to be able to place a marker on a leaflet.js powered image-map and update the position of this marker, if it gets dragged. I use the following code to try this, but it fails. I get the error 'marker not defined'. I don't know why it's not working - maybe you guys could help me out? ;)
function onMapClick(e) {
gib_uni();
marker = new L.marker(e.latlng, {id:uni, icon:redIcon, draggable:'true'};
map.addLayer(marker);
};
marker.on('dragend', function(event){
var marker = event.target;
var position = marker.getLatLng();
alert(position);
marker.setLatLng([position],{id:uni,draggable:'true'}).bindPopup(position).update();
});
In the code snippet above, marker is not defined at the time the event handler is added. Try the following where the dragend listener is added immediately following the creation of the Marker:
function onMapClick(e) {
gib_uni();
marker = new L.marker(e.latlng, {id:uni, icon:redIcon, draggable:'true'});
marker.on('dragend', function(event){
var marker = event.target;
var position = marker.getLatLng();
console.log(position);
marker.setLatLng(position,{id:uni,draggable:'true'}).bindPopup(position).update();
});
map.addLayer(marker);
};
You were also missing a bracket at the end of your new L.Marker() line.
You also put position
into an array in the call to setLatLng
but it is already a LatLng
object.
