The below code will work -

var links = document.querySelectorAll('a.className');
for (i = 0; i < links.length; i++) {
  links[i].innerHTML = '<span data-hover="' + links[i].innerHTML + '">' + links[i].innerHTML + '</span>'
}
<a href="#">Paris</a>
<a href="#" class="className">London</a>
<a href="#">Berlin</a>
