index.js

function sortList() {
  var list, i, switching, b, shouldSwitch;
  list = document.getElementById("[id of the ul tag or the list you want to sort]");
  switching = true;
  /* Make a loop that will continue until no switching has been done: */
  while (switching) {
    // Start by saying: no switching is done:
    switching = false;
    b = list.getElementsByTagName("LI");
    // Loop through all list items:
    for (i = 0; i < (b.length - 1); i++) {
      // Start by saying there should be no switching:
      shouldSwitch = false;
      /* Check if the next item should switch place with the current item: */
      if (b[i].innerHTML.toLowerCase() > b[i + 1].innerHTML.toLowerCase()) {
        /* If next item is alphabetically lower than current item, mark as a switch and break the loop: */
        shouldSwitch = true;
        break;
      }
    }
    if (shouldSwitch) {
      /* If a switch has been marked, make the switch and mark the switch as done: */
      b[i].parentNode.insertBefore(b[i + 1], b[i]);
      switching = true;
    }
  }
