Javascript variable value in a class of an element?

Question

I want to put the value of javascript variable inside a class of </a>.

<script type="text/javascript">
    $('#sp-pt-151').countdown('2016/09/02', function(event) {
        $(this).html(event.strftime('%n'));
        var dd = event.strftime('%n');
    });
</script>

HTML

<a href="#"class="avatar-container p-dd personal">
     <img src="images/train.png" alt="" width:"100px" hieght:"100px" class="avatar"/>
</a>

As you can see in the "a" element class p-dd. I want the value of dd in it.

You can do it with:

$('#sp-pt-151').countdown('2016/09/02', function(event) {
    $(this).html(event.strftime('%n'));
    var dd = event.strftime('%n');

    $('a.p-dd').removeClass('p-dd').addClass('p-'+dd);

});

I suppose you have either single a element with that class, or you want to update class of all as with p-dd class.
