The typenames is a string containing one or more typename separated by whitespace. Each typename is a type, optionally followed by a period (.) and a name, such as zoom.foo and zoom.bar; the name allows multiple listeners to be registered for the same type.
but I can't get zoom.on('zoom.foo', () => { ... }) to work...
zoom.on('zoom', () => { ... }) seems to work but is problematic because it remove listeners previously registered with the same typename.
from the doc for
zoom.on(typenames[, listener]):but I can't get
zoom.on('zoom.foo', () => { ... })to work...zoom.on('zoom', () => { ... })seems to work but is problematic because it remove listeners previously registered with the same typename.
