As far as I get it, you want to know the value of the "id" search param when accessing the "details.html" page. As stated in this answer to the question "How can I get query string values in JavaScript?", you can use URLSearchParams which is simple and has good browser support.

const urlParams = new URLSearchParams(window.location.search);
const id = urlParams.get('id'); // for a search "&id=2", the value of "id" will be 2.

This will create an URLSearchParams object which parses the window.location.search string and is able to return one specific param, like "id".
