How to detect a page change, for example through a chrome extension?

Question

JavaScript

Using the extension, I add code to the page, but when you go to internal links, the site probably uses content loading, and my code in this case does not work, only if you reload the page, you need to determine that the page has changed in certain criteria, how to do this?

Answer 1

There are Mutation Events, and you can also work not at the page level, but at the HTTP level, including AJAX.
