More Examples

A <address> with a unique id.
Clicking the button displays the address content.

<footer>
  <address id="myaddress">
    Contact author: <a href="mailto:debbie@company.com">Debbie Anderson</a>,
    @debbie_anderson
  </address>
</footer>

<button onclick="show();">Show address</button>

     let element = document.getElementById("myaddress");
     alert("Address = " + element.innerHTML);

Code explanation

The id attribute assigns a unique identifier for the <address>.

When the button is clicked, JavaScript locates the <address> through the id.

It extracts the content and displays it in an alert box.
