推荐答案

正确，你不能准确地做到这一点。您可以使用 WindowEventHandlers.onunload - Web API | MDN [ ^ ]并且可能得到你需要的东西。一般来说，何时或谁登录到网络应用程序无关紧要，因此您可以考虑重新考虑您要完成的工作。

Correct, you cannot do it accurately. You can use the WindowEventHandlers.onunload - Web APIs | MDN[^] and possibly get enough of what you need. Generally speaking it should not matter when or who is logged into a web app so you may consider rethinking what it is you are trying to accomplish.
