scrollWheelZoom set as false, map is still zoomable with mouse wheel

[Oxonium]

Hey ! :)

I have a hard time disabling the scroll wheel zoom on my map. The scrollWheelZoom option is set as false, but the map is still zoomable :

Code :

_map.leafletMap.options.scrollWheelZoom = false;

Result in console :

Do you have any idea about this issue ?

Thanks a lot in advance !

The right way is map.scrollWheelZoom.disable().

Great !

I thought this option was to be set like minZoom and maxZoom. Anyway.

Thanks ;)

@mourner Why is it listed as an option then if it doesn't work? http://leafletjs.com/reference.html#map-scrollwheelzoom

@timblakely it works; if you set scrollWheelZoom: false when creating your map, it will not let you zoom with the scroll wheel.

Although not entirely apparent from the question, the issue is if you want to disable scroll wheel zoom after the map is instantiated. You can't do it by just overwriting the option, Leaflet has no way of knowing that you changed the option. Instead, you need to disable the scrollWheelZoom handler as described by @mourner above.

@perliedman Ah, sorry for the confusion.
All makes sense now, thanks.

map.scrollWheelZoom.disable(). is not working for my case.
I have initialised map earlier like :
map = new L.Map('container',
{
center: [20, 0],
zoom: 2,
attributionControl: false,
scrollWheelZoom: false
});

now on ctrl+scroll need to set scrollWheelZoom: true. Can anyone please help , how to update the leaflet properties?

@snehakamble if you want to enabled the scroll wheel again, simply use map.scrollWheelZoom.enable() instead.

I'm trying to disable an existing map scrollWheelZoom as per the above

document.addEventListener("DOMContentLoaded", function () { var existingMap = L.DomUtil.get('map-edit-field-geo-location-0-value'); existingMap.scrollWheelZoom.disable(); });

but am getting a TypeError: Cannot read properties of undefined (reading 'disable'). What am I missing?
