location: hash property

The hash property of the Location interface returns a string containing a '#' followed by the fragment identifier of the URL — the ID on the page that the URL is trying to target.

The fragment is not URL decoded. If the URL does not have a fragment identifier, this property contains an empty string, "".

<a id="myAnchor" href="/en-US/docs/Location.href#Examples">Examples</a>
<script>
  const anchor = document.getElementById("myAnchor");
  console.log(anchor.hash); // Returns '#Examples'
</script>
