How to&Answers:

The jQuery selector is wrong: $('#myTab a[href="' + activeTab + '"]'), it should be…

$('.nav-tabs a[href="' + activeTab + '"]').tab('show');

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
    localStorage.setItem('activeTab', $(e.target).attr('href'));
});

var activeTab = localStorage.getItem('activeTab');
if(activeTab){
    $('.nav-tabs a[href="' + activeTab + '"]').tab('show');
}
