Javascript如何在iOS上的Safari中确认浏览器关闭
[英]Javascript how to confirm browser close in Safari on iOS
问题描述
Is there a way in javascript to show a confirmation alert and give the user an opportunity to cancel before closing browser/tab in mobile safari? 
有没有办法在javascript中显示确认提醒并让用户有机会在关闭移动版Safari中的浏览器/标签之前取消？ Since onbeforeunload is not supported I'm wondering if there's another way to interrupt the process? 由于不支持onbeforeunload，我想知道是否有另一种方法来中断进程？

Have you looked at Apple's Documentation? 你看过Apple的文档吗？

document.unload should work but is deprecated. document.unload应该可以工作但不推荐使用。 document.pagehide is recommended. 建议使用document.pagehide 。
