Best way to make Twitter Bootstrap tabs persistent

Question

What is the best way of making these tabs persist?

http://twitter.github.com/bootstrap/javascript.html#tabs

To add some context, this is for a Ruby on Rails application. I'm passing an array [tab1, tab2] to my view, rendering both tabs and using the Bootstrap tab plugin to toggle their visibility.

This code selects the right tab depending on the #hash and adds the right #hash when a tab is clicked. (this uses jQuery)

In CoffeeScript:

$(document).ready ->
    if location.hash != ''
         $('a[href="'+location.hash+'"]').tab('show')

    $('a[data-toggle="tab"]').on 'shown', (e) ->
        location.hash = $(e.target).attr('href').substr(1)

Or in JavaScript:

$(document).ready(function() {
    if (location.hash !== '') $('a[href="' + location.hash + '"]').tab('show');
    return $('a[data-toggle="tab"]').on('shown', function(e) {
      return location.hash = $(e.target).attr('href').substr(1);
    });
});
