Wikipedia为防止误关闭或误刷新,编辑页离开时,有一个确认框:

This page is asking you to confirm that you want to leave
information you've entered may not be saved.

希望本论坛离开编辑页时可以有确认框,以防止误关闭或误刷新.

W3Schools HTML onbeforeunload Event Attribute
This event allows you to display a message in a confirmation dialog box to inform the user whether he/she wants to stay or leave the current page.
