JS + PHP $ _GET ['example']现在不工作了

So I have made a JS system to load pages, into a default div named PageContent, now I am needed to use the PHP $_GET function and it seems that my JS is making it so the URL variables do not get set.

The Pageload.js https://hastebin.com/idazuwovoz.js

The issue is when I add a variable to a URL such as example/pages/email?id=10

and then use $_GET['id'] on that page it is blank and saying it is not set, I need to keep the JS as it is a big part of the site and required, but I also need the PHP $_GET to work, can anyone help me solve this issue, please.

Try including

let newUrl='inc/pages' +url+'.php'; alert(newUrl) ;

after one of your url.replace lines to see the actual url you are getting
