Is getActiveOverlayLayers() asynchronous? about leaflet.activelayers HOT 9 CLOSED

Thanks for the report! I will have time for this only on the weekend =(

@petemills I have now only one map overlay configuration. The Clouds from TestLayers.js. Can you please share with me the Overlay map configurations that you use? It would be very nice to have them in the format of TestLayers.js as the Clouds are:

  this.clouds = {
    name: 'Clouds',
    layer: L.tileLayer(
        'http://{s}.tile.openweathermap.org/map/clouds/{z}/{x}/{y}.png', {
          attribution: 'Map data &copy; <a href="http://openweathermap.org">OpenWeatherMap</a>'
          , opacity: 0.5
        }
    )
  }

Hey, unfortunately, I can't share the layers I'm working with as they're confidential, sorry :(. This should occur with any set of overlay layers though. If it's any consolation; I've managed to do what I was trying to do without having to use this functionality and what I was trying to do might be an incorrect use of the plugin, rather than a bug/issue!

Hi! Sorry that I returned so lately to the issue. There are still some thing to clarify. Please explain to me what the onadd event did you mean? As I can see now there are only two places in Leaflet that can fire such event: L.Marker and L.Path.
How can I attach to the event, that you've meant?

Hi, sorry for not responding. I completely forgot! I found a way around this in the end (using a completely different method) and can't remember exactly what I was doing! I believe the onadd was fired simply when I added a marker to the map. I then wanted to push that new layer (marker) into an array to store it's position relative to other layers.

Thing is, every time I added a marker and the onadd function fired, getActiveLayers() was called. My question was: is that function asynchronous because it seemed that the rest of the function (pushing the layer into the array) carried on without the getActiveLayers() function returning. Not a problem anymore though let me know if you need any clarification.

Cheers.

I'm having a very similar problem:
I'm using a map with several overlay layers and saving the selected ones in the url. I have something like this:

map.on('overlayadd', function () {
    console.log(control.getActiveOverlayLayers());
});

The problem is that when you see the output of console.log, it's always on the previous state. I think it may be because the variable _activeOverlayLayers is being updated after the event's call. By the moment, my workaround is as follows:

map.on('overlayadd', function () {
    setTimeout(function () {
        console.log(control.getActiveOverlayLayers());
    }, 1);
});
