I have one function called loadmap(){} where im creating map.Im loading this function with
ionViewDidEnter() {
this.loadmap();
}
Inside loadmap i have
this.map = leaflet.map("map").fitWorld();
thats how i initialize map
This is how i remove map when user changes tab.
ionViewDidLeave(){
this.map.remove();
}
This is my .locate function:
var usermarker;
this.map.locate({
setView: true,
maxZoom: 120,
watch:true,
enableHighAccuracy:true
}).on("locationfound", e => {
if (!usermarker) {
usermarker = new L.marker(e.latlng).addTo(this.map);
} else {
usermarker.setLatLng(e.latlng);
}
}).on("locationerror", error => {
if (usermarker) {
this.map.removeLayer(usermarker);
usermarker = undefined;
}
});
The problem is in first time .locate function works.but if i change tab and go back to map tab .locate function doesnt work.if i remove watch option it works.
Thanks
You have to call map.stopLocate()
besides map.remove()
:
Stops watching location previously initiated by
map.locate({watch: true})
Live demo: https://plnkr.co/edit/PKMPjfX3zD3QdWmEI0iX?p=preview (use the "Toggle map" button to simulate your changing tabs)
That being said, it is true that Leaflet could automatically do this when using the remove
map method. => Merged in PR Leaflet/Leaflet#5893
