Preventing map move on zoom in Leaflet?

Question

How to prevent the map from moving when a user zooms in with scrollwheel?

I would like the center to be preserved in any case.

var mymap = L.map('spotmap', {
   dragging: false
}).setView(spot_LatLng, 18);

var marker = L.marker(spot_LatLng).addTo(mymap);

Answer 1

Set scrollWheelZoom option to 'center' when defining map:

var mymap = L.map('spotmap', {
   dragging: false,
   scrollWheelZoom: 'center'
}).setView(spot_LatLng, 18);
