How can I select the current DIV ?

How can I select the current DIV ?

Hi,
I need to use a lot of progressbar in a html page,
to handle each progressbar I am using a bar_id (each progressbar has a different bar_id):

<div class="progressbar<%= bar_id %> "></div>

<script type='text/javascript'>
  $("div .progressbar<%= bar_id %>").progressbar({value: <%= val %>});
</script>

Are there some other way to do that ?
I'd like to remove the bar_id,
and use the "THIS" selector to select the current div:

<div class="progressbar">
      <script type='text/javascript'>
              $(this).progressbar({value: <%= val %>});
      </script>
</div>

but it doesn't work.
Do you have any idea how I can accomplish that ?

thank you,
Alessandro
