I know this question was asked before and answered in the following post:

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

However, given my limited knowledge of scripting, I have not been able to get this to work on my website. After putting the code in my html page the tabs still go to the first and active one on page reload.

Please can someone share a working example of the solution presented in the link above.

My code looks like this:

<div class="tabbable" style="margin-bottom: 8px;">
        <ul class="nav nav-tabs">
          <li class="active"><a href="#tab1" data-toggle="tab">My Career Centre</a></li>
          <li class=""><a href="#tab2" data-toggle="tab">Hiring Companies</a></li>
          <li class=""><a href="#tab3" data-toggle="tab">Training Providers</a></li>
          <li class=""><a href="#tab4" data-toggle="tab">Advertise</a></li>
          <li class=""><a href="#tab5" data-toggle="tab">Graduate Opportunities</a></li>
          <li class=""><a href="#tab6" data-toggle="tab">Career Forum</a></li>
        </ul>           
        <script type="text/javascript">
                  $(function() 
                    { 
                      $('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');
                      }
                    });
            </script>

        <div class="tab-content" style="padding: 0 5px;">
           <div class="tab-pane active" id="tab1">

Can you share your code or a link to an example? The code you linked uses localstorage which is not available in all browsers. – Adam Heath
@AdamHeath, Hi, Thanks for your response. I've just updated my question with the code I'm using – Grand Masta D
Try printing the $(e.target).attr('id') in console? I'm not too familiar with bootstrap tabs, but seems like e.target could be your a elements and thus the attribute to look up would be href (or data-target) – Tommi Komulainen

As Tommi Komulainen wrote: e.target contains the full url including the hash. You only need the hash. So use e.target.toString().split('#')[1]); or even better $(this).attr('href') $('#'+lastTab).tab('show'); applies the .tab() on the div with id = #{lastTab} while you need to apply on the link (a tag) with data-toggle. So use: $('a[href=#' + lastTab + ']').tab('show'); here.

The complete function to use:

                  $(function() 
                    { 
                      $('a[data-toggle="tab"]').on('shown', function () {
                        //save the latest tab; use cookies if you like 'em better:
                        localStorage.setItem('lastTab', $(this).attr('href'));
                       });

                      //go to the latest tab, if it exists:
                      var lastTab = localStorage.getItem('lastTab');
                      if (lastTab) {
                         $('a[href=' + lastTab + ']').tab('show');
                      }
                      else
                      {
                        // Set the first tab if cookie do not exist
                        $('a[data-toggle="tab"]:first').tab('show');
                      }
                  });

update: see https://stackoverflow.com/a/16016592/1596547 so remove the active class from your source and set the first tab active when lastTab is not set.

I prefer to use a pushstate.

It seems more like "The web way..." to me and it allows me to have external links pointing right to the tab I want to show.

This is my function:

function setBootstrapTabs()
{
    var activeTab = "#" + getParameterByName("submenu");

    $('a[data-toggle="tab"]').on('shown', function () {
        //save the latest tab;
        var new_url = updateUrlParam("submenu",
            $(this).attr('href').replace("#",""));
        window.history.replaceState({
                turbolinks: true, position: Date.now()
            }, document.title, new_url
        );
    });

    if (activeTab.length > 0) {
        $('a[href=' + activeTab + ']').tab('show');
    }
};
