I'm trying to locate the user when the website is fully loaded. I'm using the newest MapBox API (JavaScript)
Is it possible to do that without requiring the user to click on the top right button on the map?
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v11',
center: [0,0],
zoom: 15 // starting zoom
});
// Add geolocate control to the map.
map.addControl(new mapboxgl.GeolocateControl({
positionOptions: {
enableHighAccuracy: true
},
trackUserLocation: true
}));

Reset to default 4Yes, you have to use trigger() to activate the tracking in a programmed way.
// Initialize the geolocate control.
var geolocate = new mapboxgl.GeolocateControl({
positionOptions: {
enableHighAccuracy: true
},
trackUserLocation: true
});
// Add the control to the map.
map.addControl(geolocate);
map.on('load', function() {
geolocate.trigger(); //<- Automatically activates geolocation
});

try with this example, it's work for me
