Load multiple files

[sinanerdem]

Hello, I have multiple geojsons to add to a map. I want to load each of them one by one. But after loading all of them, I will add them to a featuregroup and then do some operations like centering the map, etc. I want to use data:loaded. It is ok if I load only one file. But I dont know how if there are multiple loads.

I found a method by jQuery: http://api.jquery.com/deferred.done/
But it does not work for Leaflet Ajax.

Any ideas?
