javascript - How to prevent window.onhashchange?

Question

window.onhashchange will be triggered when the event is fired.

Can I ask client whether to change before onhashchange?

Something like onbeforeunload.

Thanks in advance.

你可以模拟一下。您将当前值存储window.location.hash在某个变量 H 中。在处理程序中onhashchange弹出您想要的任何警报，然后根据用户的响应，将新值保存到 H（如果用户确认）或将其重置为 H 中的先前值（如果用户取消）。你想要这样的行为吗？
