Let's say I have this URL in the address bar:
Also I have an anchor that links to
<a id="lang" href="https://www.example.com/en.html">Change Language</a>
What I wanted to archive is to append to that anchor the #myhash tag but only if it's present in the current URL. If not, don't append anything.
Check if window.location.hash
is set and that it isn't just a '#'
then apply to the anchor
// for demo only set hash
history.pushState(null, null, '#someVal')
const urlHash = location.hash,
langLink = document.querySelector('#lang');
if (urlHash && urlHash !== '#') {
langLink.hash = urlHash;
}
console.log('New href=',langLink.href)
<a id="lang" href="https://www.example.com/en.html">Change Language</a>
