        e.preventDefault();
        e.stopPropagation();

推荐答案

您不能完全阻止用户离开页面(这将导致垃圾邮件/广告网站上的大量滥用，这些网站试图让您留在网站上页)，但您可以显示诸如会引起用户确认提示的窗口之类的内容.看看防止网页使用JavaScript导航 a>可以引导您朝着正确的方向前进.

You can't outright prevent a user from leaving the page (This would lead to much abuse on spam/advertisement sites who try to get you to stay on a page), but you can show things such as a window which causes a confirm prompt to the user. Have a look at Prevent a webpage from navigating away using JavaScript which can lead you to the right direction of what you're trying to accomplish.
