The ariaCurrent property of the Element interface reflects the value of the aria-current attribute, which indicates the element that represents the current item within a container or set of related elements.
A string with one of the following values:
"page"Represents the current page within a set of pages.
"step"Represents the current step within a process.
"location"Represents the current location, for example the current page in a breadcrumbs hierarchy.
"date"Represents the current date within a collection of dates.
"time"Represents the current time within a set of times.
"true"Represents the current item within a set.
"false"Does not represent the current item within a set.
In this example a set of links are used for site navigation. The aria-current attribute indicates the current page. The value page is incorporated into the screen reader announcement. Using ariaCurrent we can update that value.
<nav>
<ul>
<li><a id="link-home" href="/" aria-current="page">Home</a></li>
<li><a href="/">About</a></li>
<li><a href="/">Contact</a></li>
</ul>
</nav>let el = document.getElementById("link-home");
console.log(el.ariaCurrent); // "page"
el.ariaCurrent = "tab";
console.log(el.ariaCurrent); // "tab"
