jQuery core tabs script - multiple instances?

Question

I have the following jQuery script on my site to switch tabs without reloading the page. I'm using jQuery core v1.3.2 (NOT jQuery UI)

<!-- JS -->
<script type="text/javascript">
    $(function() {
        var tabify = function () {
            var id = $('#content > div').hide().attr('aria-hidden', 'true').filter(window.location.hash || ':first').show().attr('aria-hidden', 'false').attr('id');
            $('#content > ul > li').removeClass('selected').find('a[href=#' + id + ']').parent().addClass('selected');
        }
        setInterval(tabify, 100);
        tabify();
    });
</script>

<!-- HTML -->
<div id="content">

  <ul>
    <li><a href="#blog" role="tab">Blog</a></li>
    <li><a href="#videos" role="tab">Videos</a></li>
    <li><a href="#photos" role="tab">Photos</a></li>
  </ul>            

  <div id="blog" role="tabpanel" aria-labelledby="tab1" aria-hidden="false">Blog Content</div>
  <div id="videos" role="tabpanel" aria-labelledby="tab2" aria-hidden="true">Videos Content</div>
  <div id="photos" role="tabpanel" aria-labelledby="tab3" aria-hidden="true">Photos Content</div>                       

</div>

I want to add another instance of this script on the same page, but just copy/pasting this with different variable names doesn't work. Any ideas?

EDIT: Here is my HTML and JS for the second instance. The problem is when I click on a tab in the second instance, it hides all the content divs in the first instance, and vice versa. I want them to be independent of one another.

<!-- JS -->
<script type="text/javascript">
    $(function() {
        var tabifyplayer = function () {
            var idplayer = $('#discography > div').hide().attr('aria-hidden', 'true').filter(window.location.hash || ':first').show().attr('aria-hidden', 'false').attr('idplayer');
            $('#discography > ul > li').removeClass('selected').find('a[href=#' + idplayer + ']').parent().addClass('selected');
        }
        setInterval(tabifyplayer, 100);
        tabifyplayer();
    });
</script>

<!-- HTML -->
<div id="discography">
  <ul>
    <li><a href="#cor-player" role="tab">Chance of Rain (2009)</a></li>
    <li><a href="#debutcd-player" role="tab">Debut CD (2007)</a></li>
  </ul>

  <div id="cor-player" role="tabpanel" aria-labelledby="tab1" aria-hidden="false">Content Goes Here</div>
  <div id="debutcd-player" role="tabpanel" aria-labelledby="tab2" aria-hidden="true">Content Goes Here</div>
</div>

Answer 1

You have a number of regions in your code where you've hard-coded elements. I imagine you intend to use another container for the new tabs set, so you'll want to make sure that you change those parts of the code if you're going for a minimum amount of alteration.

<script type="text/javascript">
  $(function() {
    var tabify = function () {
      var id = $('#content > div') // Hard Coded content container.
                .hide()
                .attr('aria-hidden', 'true')
                .filter(window.location.hash || ':first')
                .show()
                .attr('aria-hidden', 'false')
                .attr('id');
      $('#content > ul > li') // Hard Coded tab elements.
        .removeClass('selected')
        .find('a[href=#' + id + ']')
        .parent()
        .addClass('selected');
    }
    setInterval(tabify, 100);
    tabify();
  });
</script>

Really though, you're probably better served by adjusting everything a little bit so that you're not relying on an interval.

$(function () {
  var mine = $('#content > ul > li > a').click(function () {
    $(this)
      .parent()
      .addClass('selected')
      .siblings('li')
      .removeClass('selected');

    $('#content > div')
      .filter($(this).attr('href') || ':first')
      .show().attr('aria-hidden', 'false')
      .siblings('div')
      .hide().attr('aria-hidden', 'true');
  });

  if (window.location.hash != undefined) {
    mine.filter('[href=' + window.location.hash + ']').click();
  } else {
    mine.filter(':first').click();
  }
});

I believe that second example should come close to achieving the same (though seeing your HTML Structure would help me to verify that) and will be easier to adapt for another set of elements.

I found a good solution on this page: http://stackoverflow.com/questions/2942563/jquery-tabs-multiple-sets-on-on-page

There's less code duplication this way, too. (Only thing it doesn't do is let you use the back button, but I can live with that.)

jQuery.fn.minitabs = function(speed,effect) {
  var id = "#" + this.attr('id')
  $(id + ">div:gt(0)").hide();
  $(id + ">ul>li>a:first").addClass("selected");
  $(id + ">ul>li>a").click(
    function(){
      $(id + ">ul>li>a").removeClass("selected");
      $(this).addClass("selected");
      $(this).blur();
      var re = /([_\-\w]+$)/i;
      var target = $('#' + re.exec(this.href)[1]);
      var old = $(id + ">div");
      old.hide();
      target.show()
      return false;
    }
 );
}
$('#tabset1').minitabs();
$('#tabset2').minitabs();
