javascript - localStorage.clear();从 PC 清除所有？

Question

如果我调用以下内容:

window.onbeforeunload = function() {
  localStorage.clear();
};

这会清除用户机器上的所有本地存储还是只清除我网站设置的内容？

Answer 1

来自 the spec for clear :

The clear() method must atomically cause the list associated with the object to be emptied of all key/value pairs, if there are any. If there are none, then the method must do nothing.

在上文中，此上下文中的“对象”将是 localStorage。什么是 localStorage？来自 the spec :

The localStorage object provides a Storage object for an origin.

因此，它只会清除您的来源或域的数据。
