使用jQuery tablesorter对mm/yy日期进行排序

$(document).ready(function() {
  $.tablesorter.addParser({
    id: 'mm-yy',
    is: function(s) {
      return false;
    },
    format: function(s) {
      var date = s.match(/(\d{2})\/(\d{2})/);
      return parseInt(date[1], 10) * 100 + parseInt(date[2], 10);
    },
    type: 'numeric'
  });

  $('table').tablesorter({
    headers: {
      2: {
        sorter: 'mm-yy'
      }
    }
  });
});
