refresh leaflet map: map container is already initialized

Question

I have a page where given a select to the user he can switch the leaflet map I show.

After a initial leaflet map load, my problem is when i want to refresh the map.

When you just remove a map, it destroys the div id reference, so, after remove() you need to build again the div where the map will be displayed, in order to avoid the "Uncaught Error: Map container not found".

if(map != undefined || map != null){
    map.remove();
   $("#map").html("");
   $("#preMap").empty();
   $( "
" ).appendTo("#preMap");
}
