Jquery Bootstrap 3：在页面刷新时保持选定的选项卡

我试图用Bootstrap 3刷新keep selected tab active.try 并判断了一些已经被问到的问题，但对我来说没有任何效果.不知道我错在哪里.这是我的密码

HTML

<!-- tabs link -->
<ul class="nav nav-tabs" id="rowTab">
    <li class="active"><a href="#personal-info" data-toggle="tab">Personal Information</a></li>
    <li><a href="#Employment-info" data-toggle="tab">Employment Information</a></li>
    <li><a href="#career-path" data-toggle="tab">Career Path</a></li>
    <li><a href="#warnings" data-toggle="tab">Warning</a></li>
</ul>
<!-- end: tabs link -->

<div class="tab-content">
    <div class="tab-pane active" id="personal-info">
        tab data here...
    </div>

    <div class="tab-pane" id="Employment-info">
        tab data here...
    </div>

    <div class="tab-pane" id="career-path">
        tab data here...
    </div>

    <div class="tab-pane" id="warnings">
        tab data here...
    </div>
</div>

Javascript:

// tab
$('#rowTab a:first').tab('show');

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

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