title: ajax does not work with opera
body: <p>My ajax code won't work in opera, however, it works with all other major browsers:</p>
  
  <pre><code>$(function() {  
  $("a").on('click', function(e) {
      var href = $(this).attr('href');
      $.ajaxSetup({
          beforeSend:function(xhr) { $('div.imagePlace').animate({height:      '10px'}); },
      });
      $.ajax();
      e.preventDefault();
  
      setTimeout(function() {
      $.ajax({
          url: href,
          dataType: "html",
          success:function(result) {
              $('.imagePlace').html(result)
              $('.imagePlace').animate({height: '500px'})
          }
      });
          }, 400);
  });
  
  
      });
  </code></pre>
  
  <p>Could anyone see what the problem is in opera ? Thanks in advance!</p>
