GUI 常用元素中英对照表 / 7. Action Popup

• To Sum up:
  Acknowledgement Popup: Let the user know the action has been completed or something just happened;
  Confirmation Popup: Let the user verify the action they want to proceed;
  Action Popup: Let the user take action and verify；

• Action Popup 是用户主动发起的新的任务流分支，所以称不上对之前操作的打断，样式上也有全覆盖的扩展。

• 在 Action Popup 中，操作是必须的，但确认不是必须的；比如 iOS 上的 Action Sheets 和 Material 上的 Simple Dialogs。

• 注，Persistent Bottom Sheets 是特殊形式；不同于 Popup 临时性本质 —— 操作完毕后弹层即消失 —— PBS 是永久存在的，“To display content equal in value to the primary content”。PBS 并非操作性控件，而更接近于 layout structure，类似两栏结构。

• 对应译名：
  Action Popup —— 动作弹层
