我正在使用reactJS开发一个网络应用程序，并且我正在使用本地存储来存储临时数据，如果从本地存储中删除了任何这些数据，我想将用户注销。

来自MDN

Responding to storage changes with the StorageEvent

The StorageEvent is fired whenever a change is made to the Storage object (note that this event is not fired for sessionStorage changes). This won't work on the same page that is making the changes — it is really a way for other pages on the domain using the storage to sync any changes that are made. Pages on other domains can't access the same storage objects.

在事件页面(see events.js)唯一的 JavaScript 如下:

window.addEventListener('storage', function(e) {  
  .....
});
