window.location.href发生变化时的事件

问题描述

我正在为一个站点编写一个Greasemonkey脚本，该站点在某些时候修改 location.href 。

I'm writing a Greasemonkey script for a site which at some point modifies location.href.

当 window.location.href 更改时，如何获取事件（通过 window.addEventListener 或类似的东西）页？我还需要访问指向新/修改的URL的文档的DOM。

How can I get an event (via window.addEventListener or something similar) when window.location.href changes on a page? I also need access to the DOM of the document pointing to the new/modified url.

我看过其他涉及超时和轮询的解决方案，但我想如果可能的话避免这种情况。

I've seen other solutions which involve timeouts and polling, but I'd like to avoid that if possible.

推荐答案

：

所以，使用<$ c时，听 popstate 事件并发送 popstate 事件$ c> history.pushState（）应该足以在 href 更改：

So, listening to popstate event and sending a popstate event when using history.pushState() should be enough to take action on href change:

window.addEventListener('popstate', listener);

const pushUrl = (href) => {
  history.pushState({}, '', href);
  window.dispatchEvent(new Event('popstate'));
};
