title: jquery create a unique id
body: <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>
