Confirmer 介绍
Confirmer implements a novel approach to the process of confirming an action.
normally this is achieved via a yes/no dialog Box or a button with a “confirm”
checkBox next to it. The Confirmer plugin instead sets up a single button
which changes to a “confirm the action” state if it is clicked one time. If
the button is clicked again within a specified time then the action is
confirmed, otherwise it times out and returns to its initial state.
