Ajax pageview of Google Analytics

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.
notice 1: ajaxSetup is better writeen within $( document ).ready() to be sure the google analytics api is loaded.
notice 2: the opts.url is the ajax url you write, to record corect pageview, the best way is use fullpath, such as '/folder_name/filename.php'

$(function () {
$.ajaxSetup({
    beforeSend: function (xhr, opts) {
      //avoid cache of the iOS6 Safari
      if (opts.url.indexOf('?') > 0) {
        opts.url += '&_t=' + (new Date()).getTime();
      } else {
        opts.url += '?_t=' + (new Date()).getTime();
      }
      //google analytics
      if (opts.data != undefined) {
        if (typeof (_gaq) != 'undefined') {
          _gaq.push(['_trackPageview', opts.url + '&' + opts.data]);
        }
      } else {
        if (typeof (_gaq) != 'undefined') {
          _gaq.push(['_trackPageview', opts.url]);
        }
      }
    }
  });
});

the way 2. setting in every ajax function
notice 1: to be sure the google analytics api is loaded
notice2: the beforeSend function will overwrite the beforeSend function of ajaxSetup

function JobIndexData(p) {
  var url = location.href;
  var qs = url.substr(url.indexOf('?'));
  url='job-index-data.asp' + qs + '&page=' + p;
  $.ajax({
    url: url,
    type: "POST",
    success: function (data) {
      $('#recordMore_' + p).parent().append(data);
      $('#recordMore_' + p).remove();
    },
    beforeSend: function () {
      if (typeof (_gaq) != 'undefined') {
        _gaq.push(['_trackPageview', '/mobileweb/' + url]);
      }
      if (p > 1) {
        $('#recordMore_' + p).html('loading...');
      }
    }
  });
}
