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.

Answer 1

I had the same problem on angular when switching page. I had to add this code before leaving the page to make it works:

    $scope.$on('$locationChangeStart', function( event ) {
    if(map != undefined)
    {
      map.remove();
      map = undefined
      document.getElementById('mapLayer').innerHTML = "";
    }
});

Without document.getElementById('mapLayer').innerHTML = "" the map was not displayed on the next page.
