javascript - How to change currency by changing the URL?

I have a list of items on my website with prices on it. Is it possible to change the currency prices by changing the URL content?

Is it possible if e.g. website.com/?currency=usd then if you change it to website.com/?currency=aud, it'll also change currency displayed and convert the price based on the currency on the URL? All the pages on my website are all in HTML format.

I apologize for a noob question because I have no idea how to do it. I found some answers on the internet, but I couldn't understand them. Hope you could help me out. Thanks in advance.
