If an event listener was already registered for the same type on the selected element, the existing listener is removed before the new listener is added. To register multiple listeners for the same event type, the type may be followed by an optional namespace, such as “click.foo” and “click.bar”. To remove a listener, pass null as the listener.<\/p><\/blockquote>\n
