    javascript - Leaflet.Draw edit and delete button not working - Stack Overflow

    programmeradmin1浏览0评论

    I'm using Leaflet Draw to let users draw a polyline in a map in order to measure sections. First step is to use Leaflet.Draw to let users draw the line. Leaflet.Draw includes a delete and edit button. These buttons are, however not working.

    I've (re)used working code from other projects to create the draw control and pass it a FeatureGroup and editable layers.

    // My draw Toolbar
var drawnItems = new L.FeatureGroup()
map.addLayer(drawnItems)
var drawControl = new L.Control.Draw({
  draw:{polygon: false,
        marker: false,
        circlemarker: false,
        rectangle: false,
        circle: false,
    },
  edit: {
    featureGroup: drawnItems
  }
});

map.addControl(drawControl);
map.on(L.Draw.Event.CREATED, function (e) {
   var layer = e.layer;
   map.addLayer(layer);
});

    Seems like I'm linking the feature group correctly, but for some reason the delete and edit are not working :(

    Reset to default 5

    You're adding the drawn items to map but they should be added to the layer pointed by edit.featureGroup if you want to edit them, i.e drawnItems:

    map.on(L.Draw.Event.CREATED, function (e) {
    var layer = e.layer;
    drawnItems.addLayer(layer);
});

    Here's a demo https://jsfiddle/4g5u071r/
