Using hashchange to load dynamic pages not working with secondary nav

Question

Any ideas on why this won't work. I am using the tutorial from CSS-Tricks using AJAX to load pages dynamically. This works fine up until I introduced a secondary navigation on some pages which caused pages to load normally.

This is the code I am using. I am using classes to style the different nav areas.

$(function() {

var newHash      = "",
    $mainContent = $("#main-content"),
    $pageWrap    = $("#page-wrap"),
    baseHeight   = 0,
    $el;

$pageWrap.height($pageWrap.height());
baseHeight = $pageWrap.height() - $mainContent.height();

$("nav").delegate("a", "click", function() {
    window.location.hash = $(this).attr("href");
    return false;
});

$(window).bind('hashchange', function(){

    newHash = window.location.hash.substring(1);

    if (newHash) {
        $mainContent
            .find("#guts")
            .fadeOut(200, function() {
                $mainContent.hide().load(newHash + " #guts", function() {
                    $mainContent.fadeIn(200, function() {
                        $pageWrap.animate({
                            height: baseHeight + $mainContent.height() + "px"
                        });
                    });
                    $("nav a").removeClass("current");
                    $("nav a[href="+newHash+"]").addClass("current");
                });
            });
    };

});

$(window).trigger('hashchange');

});

Those new created links do not have any events bound to them because u set delagate function on the the object which is not changed. New added objects with the same tag ("nav" here) won't get delagation.

Use:

$('#page').delegate("nav a", "click", function() {
  window.location.hash = $(this).attr("href");
  return false;
});

Also I recommend you to upgrade jQuery to the newest version and replace delegate() with on()
