I have a piece of jQuery code that, when the user changes the value of a select, it copies the value selected down to other similar selects (same CSS class) that follow the one changed, if they don't have a value already. Is there a more efficient way to do the following? It runs a bit sluggishly, at least in IE7.

```
$('.selectclass').change(function() {
  if ($(this).val() != '') {
    var baseElem = $(this);
    $('.selectclass:gt(' + $('.selectclass').index(this) + ')').each(function (i) {
      if ($(this).val() == '') {
        $(this).val(baseElem.val());
     } 
    });
  }
}); 

```
