first, to be sure the google analytics api is new version, such as

var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-xxxxxx-x']);
  _gaq.push(['_trackPageview']);

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();

the way 1. use ajaxSetup for all calls to $.ajax.

$(document).ready(function () {
  $('[placeholder]').focus(function () {
    var input = $(this);
    if (input.val() == input.attr('placeholder')) {
      input.val('');
      input.removeClass('placeholder');
    }
  }).blur(function () {
    var input = $(this);
    if (input.val() == '' || input.val() == input.attr('placeholder')) {
      input.addClass('placeholder');
      input.val(input.attr('placeholder'));
    }
  }).blur();

  $('[placeholder]').parents('form').submit(function () {
    $(this).find('[placeholder]').each(function () {
      var input = $(this);
      if (input.val() == input.attr('placeholder')) {
        input.val('');
      }
    })
  });
});
