如何使用(或可能)使用MutationObserver监视window.location.pathname的更改? [英] How to use (or is it possible) MutationObserver to monitor window.location.pathname change?

问题描述

我想知道是否可以使用MutationObserver监视window.location.pathname(或window.location.hash)中的更改.

I wonder if it is possible to use MutationObserver to monitor change in window.location.pathname (or window.location.hash).

推荐答案

否-您不能使用MutationObservers

No - you cannot use MutationObservers

新的EcmaScript 7(预览，草稿)将具有 Object.observe ，它将允许您监视任何对象.但是，这就是无法使用:观察全局对象存在安全风险，我怀疑是否有任何浏览器会允许这样做(

The new EcmaScript 7 (in preview, draft) is going to have Object.observe which will allow you to monitor any object. However, that is in not going to work: observing global objects is a security risk and I doubt that any browser will allow that (Chromium issue 494574).

此外，正如其他人指出的那样，window.location是一个系统对象(属于Location Object类型)，因此它不在 Object.observe 范围内.

Also, as other pointed out, window.location is a system object (of type Location Object) so it is not covered by Object.observe.

您可以使用已经支持Object.observe的Chrome 43进行测试: kangax.github.io/compat-table/es7/#Object.observe

You can test that with Chrome 43 which already supports Object.observe: kangax.github.io/compat-table/es7/#Object.observe

因此，唯一的解决方案是使用超时机制或使用 window.onpopstate (如果仅需要监视哈希)来监视更改.

So the only solution is to watch changes using timeout mechanism or use window.onpopstate (if you need to monitor only hash).
