CSS and jQuery links navigation: how to update the <li> class

Question

I have this jQuery code that retrieves external content using ajax without linking to the page, and I also have navigation links that have a different background color when the user is on the current page.

JQuery Code:

function loadPage(url)  //the function that loads pages via AJAX
{
    url=url.replace('#page','');    //strip the #page part of the hash and leave only the page number

    //$('#loading').css('visibility','visible');    //show the rotating gif animation
        $('.counter').html('<img src="img/ajax_load.gif" width="16" height="16" style="padding:12px" alt="loading" />');

    $.ajax({    //create an ajax request to load_page.php
        type: "POST",
        url: "load_page.php",
        data: 'page='+url,  //with the page number as a parameter
        dataType: "",   //expect html to be returned
        success: function(msg){

            if(parseInt(msg)!=0)    //if no errors
            {
                $('#change-container').html(msg);   //load the returned html into pageContet


            }
        }

    });
}

html navigation code:

<ul>
   <li class="current"><a href="#page1">Home</a></li>
   <li><a href="#page3">Replies</a></li>
   <li><a href="#page4">Favorites</a></li>
</ul>

Therefore, when someone clicks on the answer link, I want the class to lichange to the current one to indicate that you are on this page.

Answer 1

Example: http://jsfiddle.net/4cs9h/

$('ul > li > a').click(function() {
    var $th = $(this).parent();
    if( !$th.hasClass('current') ) {
        $th.addClass('current')
               .siblings('.current').removeClass('current');
        loadPage(this.href);
    }
    return false;
});

The variable $threfers to the parent <li> <a>that was clicked.

<li> current, , , loadPage(), href <a>.
