jquery create a unique id
<pre><code>$(document).ready(function() {
  $('a.menuitem').click(function() {
      var arr = 0;
      var link = $( this ), url = link.attr( "href" );
      var newDiv = $( document.createElement( 'div' ) )
      $( "#content_pane" ).append( newDiv );
      newDiv.load( url );
      return false;
  });
});
</code></pre>

<p>As you can see I am creating a <code>div</code> and adding some content to it, how would I give each <code>div</code> that is created a unique id, something like section1, section2, section3, etc?</p>
