Make anchor links refer to the current page when using

I found a solution on this site: using-base-href-with-anchors that doesn’t require jQuery, and here is a working snippet:

<base href="https://example.com/">

<a href="http://stackoverflow.com/test">/test</a>
<a href="javascript:;" onclick="document.location.hash="test";">Anchor</a>

Or without inline JavaScript, something like this:

document.addEventListener('DOMContentLoaded', function(){
  var es = document.getElementsByTagName('a')
  for(var i=0; i<es.length; i++){
    es[i].addEventListener('click', function(e) {
      e.preventDefault()
      document.location.hash = e.target.getAttribute('href')
    })
  }
})
