it's not necessarily must implement a looping but you can try use jQuery selector

jQuery Selectors

Try to use jQuery:
$("span").each(function( index ) {
  /*do stuff to current $( this ) here*/

Open in new window

If you want to or have use pure JavaScript:
var spans = document.getElementsByTagName('span');
var l = spans.length;
for (var i=0;i<l;i++) {
        /*do stuff to current spans[i] here*/

Open in new window
