Inspired by https://github.com/tinuzz/leaflet-messagebox
Leaflet.MessageboxV2 is a simple control inspired by https://github.com/tinuzz/leaflet-messagebox. It does the same thing but with added functionality like defining your own class and making the message box permanent.
According to the original author @tinuzz
There are two ways to define the message box
var options = { timeout: 5000 }
var box = L.control.messagebox(options).addTo(map);
and
var map = L.map( 'mapdiv', {'messagebox': true, ...} );
map.messagebox.options.timeout = 5000;
To show the message:
box.show( 'This is the message' );
or, when implicitly used with the map:
map.messagebox.show( 'This is the message' );
SetClass: (string) you can define your class without altering your CSS code. It also work if you are using custom frameworks such as Bootstrap.
timeout: (int) you can now disable the timeout (disappearing messagebox) by setting the value to 0. This will make the message box permanent.
