once()

Just like on, but causes the bound callback to only fire once before being moved. Handy for saying "the next time that X happens, do this".

Arguments

    Name of the event that you want to stop listening to
  • eventCallback callback
    If no callback is provided, all event handlers for the eventName will be removed.
  • context object
    If no context is provided, all event bindings for the eventName, eventCallback combination will be removed

Return value

None (undefined).
