Been on this one for a while now. Basically, I need to check where a `href` on an anchor tag with the class `.pdf-download` is empty, and if it is, hide it.

I have attempted a few options but with no luck. This is what i have so far:

```
$("a.pdf-download").each(function (i) {
  if ($('[href]:empty',this).length == 1) { 
    $(this).hide();
  } else {
    $(this).show();
  }
});

```
