jQuery's One - Fire once with multiple event types

Question

Is there a way to fire a single function once when any event is raised?

For example, if I have the following function: (demo in jsfiddle)

Answer 1

Instead of using .one, use .on and remove the binding manually with .off.

$('input').on('mouseup keyup', function(e){
    console.log(e.type);
    $(this).off('mouseup keyup');
});

This can be done a little more elegantly with namespaces:

$('input').on('mouseup.foo keyup.foo', function(e){
    console.log(e.type);
    $(this).off('.foo');
});

This allows us to use a single identifier (foo) to remove any number of bindings, and we won't affect any other mouseup or keyup bindings the element may have.
