How can I add text from a DIV to a textarea?

I have this now:

    $('.oquote').click(function() { 
      $('#replyBox').slideDown('slow', function() {
      var quote = $('.container').text();   
         $('#replyBox').val($('#replyBox').val()+quote);   
        // Animation complete.
      });    
    });

Just append() the text nodes:

$('#replyBox').append(quote);
