I'm not sure why your script is working in Chrome, all browsers should behave in the same way with this. Is it possible, that the code block where you remove the event listener, is for some reason executed only in Chrome?
我不确定为什么您的脚本在 Chrome 中工作，所有浏览器的行为方式都应该与此相同。您删除事件侦听器的代码块是否可能出于某种原因仅在 Chrome 中执行？
Anyway, if you set window.onbeforeunload = someFunction;you can nullify it with window.onbeforeunload = null. However, if you set window.addEventListener('beforeunload', someFunction);, this event listener can't be removed with window.onbeforeunload = null. It can be removed only with removeEventListener('beforeunload', someFunction);.
无论如何，如果你设置了window.onbeforeunload = someFunction;你可以用window.onbeforeunload = null. 但是，如果您设置了window.addEventListener('beforeunload', someFunction);，则无法使用 删除此事件侦听器window.onbeforeunload = null。它只能用 删除removeEventListener('beforeunload', someFunction);。
If this answer doesn't help, please post all relevant code, like the snippet when assigning event listener, and also when trying to remove it.
如果此答案没有帮助，请发布所有相关代码，例如分配事件侦听器时以及尝试删除它时的代码段。
