How to intercept window.location change
提问by epitka
I need a way to attach some pre-processing to each assignment of the window.location. Is there a way to do this. I basically need to serialize some info, that will be used in the new location.
我需要一种方法来为 window.location 的每个分配附加一些预处理。有没有办法做到这一点。我基本上需要序列化一些信息，这些信息将在新位置使用。

You can use the beforeunloadevent to trigger your code to run prior to navigation... If you need something more specific (e.g., only navigations initiated in your code), then I recommend that you factor out code changing window.locationinto a separate function, and add a hook for your custom logic.
您可以使用该beforeunload事件触发您的代码在导航之前运行...如果您需要更具体的内容（例如，仅在您的代码中启动导航），那么我建议您将代码更改window.location为单独的函数，并添加自定义逻辑的钩子。

You may want to look at Ben Nadel's post in regard to doing this, it may be exactly what you're looking for

His example in the post talks about creating an event handler that triggers a change event when window.locationchanges
他在关于创建一个事件处理程序触发change事件时，后会谈例如window.location改变
