有没有办法在Mobile Safari for iOS设备上使用window.onbeforeunload？ [英] Is there any way to use window.onbeforeunload on Mobile Safari for iOS devices?

问题描述

看起来Apple已禁用iOS设备（iPhone，iPad，iPod Touch）的window.onbeforeunload事件。遗憾的是，我找不到任何关于此事件在Mobile Safari中不起作用的文档。

Looks like Apple has disabled the window.onbeforeunload event for iOS devices (iPhone, iPad, iPod Touch). Unfortunately I can't find any documentation as to why this event doesn't work in Mobile Safari.

有没有人知道这个函数是否有可靠的替代方案？ Android的浏览器似乎支持它很好，Safari桌面应用程序也支持onbeforeunload事件而没有问题。

Does anyone know if there's a reliable alternative to this function? Android's browser appears to support it just fine, and the Safari desktop application also supports the onbeforeunload event without issue.

推荐答案

我看到了这是一个老问题，但我最近遇到了这个问题。

I see that it's an old question, but i faced this problem recently.

我正在使用 window.unload 并且它有效在ios浏览器中很好（尽管如果你看看 Apple文档似乎已被弃用，他们建议使用 document.pagehide ）

I'm using window.unload and it works fine in ios browsers (although if you look at Apple documentation it seems to be deprecated and they recommend to use document.pagehide)
