How to keep the current tab active with twitter bootstrap after a page reload?

Answer

$(function() { 
  //for bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line
  $('a[data-toggle="tab"]').on('shown', function (e) {
    //save the latest tab; use cookies if you like 'em better:
    localStorage.setItem('lastTab', $(e.target).attr('id'));
  });

  //go to the latest tab, if it exists:
  var lastTab = localStorage.getItem('lastTab');
  if (lastTab) {
      $('#'+lastTab).tab('show');
  }
});
