How do I programatically change layers in Leaflet?

Question

I don't want to the show the layers control on the map, but I want to put some buttons somewhere else to change between layers. Is this possible to change the layer programmatically?

Answer 1

Suppose you have a map:

var map = L.map('worldmap-map').setView([37.8, -96], 4);

To remove a layer, layer1:

map.removeLayer(layer1)

To remove a control layer, ctrlLayer,

map.removeControl(ctrlLayer)

Or you want to add a layer1 to map:

layer1.addTo(map)

For an example, there is a Leaflet example : http://leafletjs.com/examples/choropleth-example.html

You could use firebug or chrome dev tools to see its source.
