如何在 html 的链接中嵌入源站地址？

Question

Assume there is a link like <a href="mysite.com">click here</a> in a footer of a website. is there any way to change this link somehow that the admin of mysite.com website could detect from which site this user is coming from?

Thank you.

You can do this

 <a href="https://example.com" onclick="this.href = 'https://example.com/?ref='+encodeURIComponent(location.host)">click here</a>
