Why attach an event handler/listener to a document’s beforeunload event?
Attaching an event handler/listener to window or document’s beforeunload event prevents browsers from using in-memory page navigation caches, like Firefox’s Back-Forward cache or WebKit’s Page Cache. The HTML specification states that calls to window.alert(), window.confirm(), and window.prompt() methods may be ignored during this event.
