Trying to figure out how to use jQuery index() buried in parent elements

I want to get the index of a group of elements (in this example, the a tags with the class myLink). They are nested within parent elements. All my efforts thus far produce a 0 index for the first item, but a -1 index for the second. An example of the structure I'm looking at is:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="containerOne">
  <ul class="listOne">
    <li>
      <a class="myLink" href="blah">Link Text</a>
    </li>
    <li>
      <a class="myLink" href="moreBlah">More Link Text</a>
    </li>
  </ul>
</div>
<script>
    $('.myLink').on('click', function(){
        alert($(this).index($('.myLink')));
        alert($(this).index($('.containerOne .listOne a')));
        alert($(this).index($('.containerOne .listOne li a')));
        alert($(this).index($('.containerOne .listOne .myLink')));
        alert($(this).index($('.containerOne .listOne li .myLink')));
        alert($(this).index($('.containerOne .listOne a.myLink')));
        alert($(this).index($('.containerOne .listOne li a.myLink')));
        alert($(this).index());
        return false;
    })
</script>

You should call .index() on a collection of items (such as $('.myLink')), and pass this as an argument - then you'll get the index of this within the collection

// GeekInTheBox - please fill this out
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="containerOne">
  <ul class="listOne">
    <li>
      <a class="myLink" href="blah">Link Text</a>
    </li>
    <li>
      <a class="myLink" href="moreBlah">More Link Text</a>
    </li>
  </ul>
</div>
<script>
    $('.myLink').on('click', function(){
        alert($('.myLink').index(this));
        return false;
    })
</script>
