i implemented leaflet and leafletDraw in my Angular6 app, it works fine and i can trigger the create event and add the polygon to my map, but when i try to delete or edit my polygon i can't find which shape is deleted or edited:
ngOnInit() {
const myMap = this.mapElement.nativeElement;
const map = L.map(myMap).setView([35.6892, 51.3890], 5);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: 'Data © OpenStreetMap',
maxZoom: 18,
}).addTo(map);
const editableLayers = new L.FeatureGroup();
map.addLayer(editableLayers);
if (this.type === 'marker') {
this.marker = MarkerOptions;
if (this.data) {
L.marker(this.data, MarkerOptions).addTo(editableLayers).bindPopup('I am popup');
}
} else if (this.type === 'polygon') {
this.polygon = {
allowIntersection: false,
drawError: {
message: '<strong>Oh snap!<strong> you can\'t draw that!'
},
shapeOptions: {}
};
if (this.data) {
L.polygon(this.data).addTo(editableLayers);
}
}
const drawPluginOptions: LeafletControls.Control.DrawConstructorOptions = {
position: 'topright',
draw: {
polyline: false,
polygon: this.polygon,
circle: false,
rectangle: false,
circlemarker: false,
marker: this.marker
},
edit: {
featureGroup: editableLayers,
remove: {},
edit: {
selectedPathOptions: {
stroke: false ,
color : '#e10010',
weight : 500
}
}
}
};
const drawControl = new L.Control.Draw(drawPluginOptions);
map.addControl(drawControl);
map.once(L.Draw.Event.CREATED, (e: any) => {
console.log('lia e' , e);
this.layer = e.layer;
// if (type === 'marker') {
// layer.bindPopup('A popup!');
// }
editableLayers.addLayer(this.layer);
});
map.on('draw:edited', (e: any) => {
console.log('lia edit' , e , this.layer); //unable to trigger which shape is.
});
map.on('draw:deleted', (e: any) => {
console.log('lia delete' , e ); //unable to trigger which shape is.
console.log(this.layer);
});
}
The draw:edited and draw:deleted events pass you a LayerGroup which contains the layers that were edited/deleted.
map.on('draw:edited', (e: any) => {
var editedlayers = e.layers;
editedlayers.eachLayer(function(layer) { // Do something with the edited layer
});
});

I am trying to create a cluster map with multiple locations in the same area. Now, I have this pop-up with data which is coming from my API. I have a click event that toggles the pop-up on click for each location. But the problem is even when I specified the click unique ID to toggle it still opens all the pop-ups. Also, the zoom is not working for the clusters count circles.
This is my code:

tempMarker.push(v.getLatLng())
})
console.log({tempMarker});
**for (let i in map._layers) {

i'm trying to get touchstart or touchmove events working in leaflet with polygon, on mobile, i need something very responsive like mousedown in pc's browser.
this wasn't working :
L.Map.mergeOptions({
touchExtend: true
});
L.Map.TouchExtend = L.Handler.extend({
initialize: function (map) {
this._map = map;
this._container = map._container;
this._pane = map._panes.overlayPane;
},
addHooks: function () {
L.DomEvent.on(this._container, 'touchstart', this._onTouchStart, this);
L.DomEvent.on(this._container, 'touchend', this._onTouchEnd, this);
},
removeHooks: function () {
L.DomEvent.off(this._container, 'touchstart', this._onTouchStart);
L.DomEvent.off(this._container, 'touchend', this._onTouchEnd);
},
_onTouchStart: function (e) {
if (!this._map._loaded) { return; }
var type = 'touchstart';
var containerPoint = this._map.mouseEventToContainerPoint(e),
layerPoint = this._map.containerPointToLayerPoint(containerPoint),
latlng = this._map.layerPointToLatLng(layerPoint);
this._map.fire(type, {
latlng: latlng,
layerPoint: layerPoint,
containerPoint: containerPoint,
originalEvent: e
});
},
_onTouchEnd: function (e) {
if (!this._map._loaded) { return; }
var type = 'touchend';
this._map.fire(type, {
originalEvent: e
});
}
});
L.Map.addInitHook('addHandler', 'touchExtend', L.Map.TouchExtend);
and this neither :
L.Map.mergeOptions({
touchExtend: true
});
L.Map.TouchExtend = L.Handler.extend({
initialize: function (map) {
this._map = map;
this._container = map._container;
this._pane = map._panes.overlayPane;
},
addHooks: function () {
L.DomEvent.on(this._container, 'touchstart', this._onTouchStart, this);
},
removeHooks: function () {
L.DomEvent.off(this._container, 'touchstart', this._onTouchStart);
},
_onTouchStart: function (e) {
if (!this._map._loaded) { return; }
var type = 'touchstart';
var containerPoint = this._map.mouseEventToContainerPoint(e),
layerPoint = this._map.containerPointToLayerPoint(containerPoint),
latlng = this._map.layerPointToLatLng(layerPoint);
this._map.fire(type, {
latlng: latlng,
layerPoint: layerPoint,
containerPoint: containerPoint,
originalEvent: e
});
}
});
L.Map.addInitHook('addHandler', 'touchExtend', L.Map.TouchExtend);
var map = L.map('map', { zoomControl:false }).setView([50.594412, 5.863625], 15);
L.tileLayer('https://cartodb-basemaps-{s}.global.ssl.fastly.net/dark_all/{z}/{x}/{y}.png', {
maxZoom: 22, minZoom: 5, zoomControl:false ,
id: 'mapbox.streets'
}).addTo(map);
map.on('touchstart', function() {
alert('touchmove');
});
with the 2 solutions above, no error, but it's just not triggering touch events on mobile...
i also tried to reduce the contextmenu delay, but i didn't find how.
i think about using html element insteed of leaflet's polygons but
it will not be so nice
Am using vue and have installed the vue-mapbox component located here: https://soal.github.io/vue-mapbox/#/quickstart
I have updated the js and css to the latest versions also that gets added to the index.html:
<!-- Mapbox GL CSS -->
<link href="https://api.tiles.mapbox.com/mapbox-gl-js/v0.51.0/mapbox-gl.css" rel="stylesheet" />
<!-- Mapbox GL JS -->
<script src="https://api.tiles.mapbox.com/mapbox-gl-js/v0.51.0/mapbox-gl.js"></script>
I am trying to utilize this component to set the default view of the map bounds using either center or bounds or fitBounds to a list of Lng,Lat coordinates. So, basically, how to plug in lng,lat coordinates and have the map default to centering these coordinates inside of the container?
Here's a Component I created, called Map in vue to output the mapbox using the component vue-mapbox listed above:
<template>
<b-row id="map" class="d-flex justify-content-center align-items-center my-2">
<b-col cols="24" id="map-holder" v-bind:class="getMapType">

</b-col>
</b-row>
</template>
<script>
import { MglMap } from 'vue-mapbox'
export default {
components: {
MglMap
},
data () {
return {
accessToken: 'pk.eyJ1Ijoic29sb2dob3N0IiwiYSI6ImNqb2htbmpwNjA0aG8zcWxjc3IzOGI1ejcifQ.nGL4NwbJYffJpjOiBL-Zpg',
mapStyle: 'mapbox://styles/mapbox/streets-v9', // options: basic-v9, streets-v9, bright-v9, light-v9, dark-v9, satellite-v9
zoom: 9,
map: {}, // Holds the Map...
fitBounds: [[-79, 43], [-73, 45]]
}
},
props: {
interactive: {
default: true
},
resizeMap: {
default: false
},
mapType: {
default: ''
},
center: {
type: Array,
default: function () { return [4.899, 52.372] }
}
},
computed: {
getMapType () {
let classes = 'inner-map'
if (this.mapType !== '') {
classes += ' map-' + this.mapType
}
return classes
}
},
watch: {
resizeMap (val) {
if (val) {
this.$nextTick(() => this.$refs.mapbox.resize())
}
},
fitBounds (val) {
if (this.fitBounds.length) {
this.MoveMapCoords()
}
}
},
methods: {
loadMap () {
if (this.map === null) {
this.map = event.map // store the map object in here...
}
},
MoveMapCoords () {
this.$refs.mapbox.fitBounds(this.fitBounds)
}
}
}
</script>
<style lang="scss" scoped>
#import '../../styles/custom.scss';
#map {
#map-obj {

#map-holder {

#map-obj {

}
}

}
}
</style>
So, I'm trying to use fitBounds method here to get the map to initialize centered over 2 Lng,Lat coordinates here: [[-79, 43], [-73, 45]]
How to do this exactly? Ok, I think I might have an error in my code a bit, so I think the fitBounds should look something like this instead:
fitBounds: () => {
return { bounds: [[-79, 43], [-73, 45]] }
}
In any case, having the most difficult time setting the initial location of the mapbox to be centered over 2 or more coordinates. Anyone do this successfully yet?
Ok, so I wound up creating a filter to add space to the bbox like so:
Vue.filter('addSpaceToBBoxBounds', function (value) {
if (value && value.length) {
var boxArea = []
for (var b = 0, len = value.length; b < len; b++) {
boxArea.push(b > 1 ? value[b] + 2 : value[b] - 2)
}
return boxArea
}
return value
})
This looks to be good enough for now. Than just use it like so:
let line = turf.lineString(this.markers)
mapOptions['bounds'] = this.$options.filters.addSpaceToBBoxBounds(turf.bbox(line))
return mapOptions
setting the initial location of the map to be centered over 2 or
more coordinates
You could use Turf.js to calculate the bounding box of all point features and initialize the map with this bbox using the bounds map option:
http://turfjs.org/docs#bbox
https://www.mapbox.com/mapbox-gl-js/api/#map
I created a few simple functions to calculate a bounding box which contains the most southwestern and most northeastern corners of the given [lng, lat] pairs (markers). You can then use Mapbox GL JS map.fitBounds(bounds, options?) function to zoom the map to the set of markers.
Always keep in mind:
lng (lon): longitude (London = 0, Bern = 7.45, New York = -74)
→ the lower, the more western
lat: latitude (Equator = 0, Bern = 46.95, Capetown = -33.9)
→ the lower, the more southern
getSWCoordinates(coordinatesCollection) {
const lowestLng = Math.min(
...coordinatesCollection.map((coordinates) => coordinates[0])
);
const lowestLat = Math.min(
...coordinatesCollection.map((coordinates) => coordinates[1])
);
return [lowestLng, lowestLat];
}
getNECoordinates(coordinatesCollection) {
const highestLng = Math.max(
...coordinatesCollection.map((coordinates) => coordinates[0])
);
const highestLat = Math.max(
...coordinatesCollection.map((coordinates) => coordinates[1])
);
return [highestLng, highestLat];
}
calcBoundsFromCoordinates(coordinatesCollection) {
return [
getSWCoordinates(coordinatesCollection),
getNECoordinates(coordinatesCollection),
];
}
To use the function, you can just call calcBoundsFromCoordinates and enter an array containing all your markers coordinates:
calcBoundsFromCoordinates([
[8.03287, 46.62789],
[7.53077, 46.63439],
[7.57724, 46.63914],
[7.76408, 46.55193],
[7.74324, 46.7384]
])
// returns [[7.53077, 46.55193], [8.03287, 46.7384]]
Overall it might even be easier to use Mapbox' mapboxgl.LngLatBounds() function.
As mentioned in the answer from jscastro in Scale MapBox GL map to fit set of markers you can use it like this:
const bounds = mapMarkers.reduce(function (bounds, coord) {
return bounds.extend(coord);
}, new mapboxgl.LngLatBounds(mapMarkers[0], mapMarkers[0]));
And then just call
map.fitBounds(bounds, {
padding: { top: 75, bottom: 30, left: 90, right: 90 },
});
If you don't want to use yet another library for this task, I came up with a simple way to get the bounding box, here is a simplified vue component.
Also be careful when storing your map object on a vue component, you shouldn't make it reactive as it breaks mapboxgl to do so
import mapboxgl from "mapbox-gl";
export default {
data() {
return {
points: [
{
lat: 43.775433,
lng: -0.434319
},
{
lat: 44.775433,
lng: 0.564319
},
// Etc...
]
}
},
computed: {
boundingBox() {
if (!Array.isArray(this.points) || !this.points.length) {
return undefined;
}
let w, s, e, n;
// Calculate the bounding box with a simple min, max of all latitudes and longitudes
this.points.forEach((point) => {
if (w === undefined) {
n = s = point.lat;
w = e = point.lng;
}
if (point.lat > n) {
n = point.lat;
} else if (point.lat < s) {
s = point.lat;
}
if (point.lng > e) {
e = point.lng;
} else if (point.lng < w) {
w = point.lng;
}
});
return [
[w, s],
[e, n]
]
},
},
watch: {
// Automatically fit to bounding box when it changes
boundingBox(bb) {
if (bb !== undefined) {
const cb = () => {
this.$options.map.fitBounds(bb, {padding: 20});
};
if (!this.$options.map) {
this.$once('map-loaded', cb);
} else {
cb();
}
}
},
// Watch the points to add the markers
points: {
immediate: true, // Run handler on mount (not needed if you fetch the array of points after it's mounted)
handler(points, prevPoints) {
// Remove the previous markers
if (Array.isArray(prevPoints)) {
prevPoints.forEach((point) => {
point.marker.remove();
});
}
//Add the new markers
const cb = () => {
points.forEach((point) => {
// create a HTML element for each feature
const el = document.createElement('div');
el.className = 'marker';
el.addEventListener('click', () => {
// Marker clicked
});
el.addEventListener('mouseenter', () => {
point.hover = true;
});
el.addEventListener('mouseleave', () => {
point.hover = false;
});
// make a marker for each point and add to the map
point.marker = new mapboxgl.Marker(el)
.setLngLat([point.lng, point.lat])
.addTo(this.$options.map);
});
};
if (!this.$options.map) {
this.$once('map-loaded', cb);
} else {
cb();
}
}
}
},
map: null, // This is important to store the map without reactivity
methods: {
mapLoaded(map) {
this.$options.map = map;
this.$emit('map-loaded');
},
},
}
It should work fine as long as your points aren't in the middle of the pacific juggling between 180° and -180° of longitude, if they are, simply adding a check to invert east and west in the return of the bounding box should do the trick

New2Dis,
Here is your example running in a jsfiddle.
computed: {
events: function () {
return this.store.events;
}
},
watch: {
events: function (val) {
this.removeEvents();
this.addEvents(val);
}
},
methods: {
addEvents(events) {
console.log("hoi")
const map = this.map;
const markers = L.markerClusterGroup();
const store = this.$store;
events.forEach(event => {
let marker = L.marker(event.latlng, { draggable: true })
.on("click", el => {
//store.commit("locationsMap_center", event.latlng);
})
.bindPopup(`<b> ${event.id} </b> ${event.name}`)
.addTo(this.map);
markers.addLayer(marker);
});
map.addLayer(markers);
this.markers = markers;
},
removeEvents() {
if (this.markers != null) {
this.map.removeLayer(this.markers);
this.markers = null;
}
}
},
I did replace some things to make it works, like the $store as I don't have it, and removeEvent was not written correctly, so I'm not sure what I actually fixed...
I have also created a plugin to make it easy to use Leaflet with Vue.
You can find it here
You will also find a plugin for Cluster group here
Give it a try and let me know what you think.
