When I clear all marker I have error
Uncaught TypeError: Cannot read property 'lng' of undefined
My code:
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v9',
});
var marker = new mapboxgl.Marker().addTo(map);
marker.remove();
You need to place the marker somewhere by lng and lat. Which you didn't set.
Here's an example from MapBox Documentation Page.
var marker = new mapboxgl.Marker()
.setLngLat([30.5, 50.5])
.addTo(map);

I have a web site to displaying historic maps. The maps have been tiled and are loaded as a tilelayer. Is there a way to getBound so I can set the map with fitBound. By default tilelayer does not have a getBounds method. I have tried making a featureGroup of the layer but that just raises an error. Am I missing something? Thanks.
// Initiate map
var map = new L.Map('map', {minZoom: 8, maxZoom: 18, zoom: 10});
// Display and set boundary
var layer = new L.TileLayer('../../maps/1866/{z}/{x}/{y}.png',{maxNativeZoom: 17});
//create featuregroup
var fgroup = new L.featureGroup([layer]);
fgroup.addTo(map);
map.fitBounds(fgroup.getBounds());
How to check cursor is moved outside the map in mapbox?
I want an event that will check cursor is moved outside the map.
Please take a look at the mouseleave event.
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v11',
center: [-74.5, 40],
zoom: 9
});
var mouseTarget = document.getElementById('map');
mouseTarget.addEventListener('mouseleave', e => {
console.log('mouseleave');
});
I am a beginner in mapbox JS GL. I am looking for a way to give the user the opportunity to change visibility of layer in mapbox on button click.
In MapBox studio I add to Basic style visible layer "regions". I tried to do so :
<script> ...
var mapp = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/terentev/ck2so0c4h1q5x1cqow0aj9nh8',
center: [34.047, 63.779],
zoom: 5.41
});
mapp.setLayoutProperty('regions','visibility','none');
But the layer does not disappear.
And when I try get layers from style:
var v = mapp.getStyle().layers;
I can't. How to do it right?
Thanks in advance!
This is layer 'regions', added to Basic style :
layer 'regions' in mapbox studion
I tried like this:
var v = mapp.getLayoutProperty('regions', 'visibility');
alert('visibility '+ v );
mapp.setLayoutProperty('country-label','visibility','visible');
v = mapp.getLayoutProperty('regions', 'visibility');
alert('visibility '+ v );
On first alert I get "visibility undefined"
but there is no result on second alert at all
Try this:
var mapp = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/terentev/ck2so0c4h1q5x1cqow0aj9nh8',
center: [34.047, 63.779],
zoom: 5.41
});
mapp.on('load', () => {
mapp.setLayoutProperty('regions','visibility','none');
})
It just looks like you're invoking setLayoutProperty before the map has properly loaded
I am working on a Nuxt, Leaflet, Mapboxgl project.
This is how I init my map:
let mapOptions = {
container: 'map',
style: 'http://linkToMapStyle.com',
attributionControl: false,
center: [13.404954, 52.520008],
zoom: 5,
minZoom: 1,
preserveDrawingBuffer: true
};
_this.map = new mapboxgl.Map(mapOptions);
I'll be loading marker data from my REST endpoint on every map moveend event. So I'll be loading and deleting markers quite a lot. That's why I wanted to use layerGroup to group all my markers so I can remove them easier.
On the map.load event I'm trying to add the layerGroup and the markers to my layerGroup:
var marker1 = L.marker([13.404954, 52.520008]);
var marker2 = L.marker([14.404954, 51.520008]);
var markers = L.layerGroup();
markers.addLayer(marker1);
markers.addLayer(marker2);
markers.addTo(_this.map)
And it's giving my errors:
Error: layers.undefined: either "type" or "ref" is required
...
Error: layers.undefined: missing required property "source"
...
Error: layers.undefined: missing required property "id"
..
All the examples I found where without specifying any type of layer options so I don't understand why this is not working for me.
I have draw direction to more then 2 park in gl mapbox.
I have try this code but not work perfectly.

there was a breaking change in a recent update of mapbox-gl-js that caused the mapbox-gl-directions plugin to error.
Here is a working jsfiddle of your code with the new versions (v2.2.0 of mapbox-gl-directions plugin and v0.22.1 of mapbox-gl-js)
