Try using the [id] selector string inside the .closest, so that closest returns the element with an ID. Note that the selector string shouldn't have "s around the id:

$('span').on('click', function() {
  var id = $(this).closest("[id]").attr("id");
  console.log(id);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="outer">outer
  <div>inner
    <span>click here</span>
  </div>
</div>
