How to reference pound sign (#) in jQuery?

I've been trying a new way to set up a website using jQuery to dynamically get the content when a link is clicked. Here is the jQuery code:

$(document).ready(function() {

 var content_loader = $('#content-loader');

 $('#nav ul li a').click(function () {
  $(this).closest('ul').find('li.active').removeClass('active');
  $(this).parent().addClas开发者_StackOverflow社区s('active');
  content_loader.load('content/' + $(this).attr('data-name') + '.html'); 
  });

 content_loader.load('content/home.html');

});

I've been doing it this way since I have a song in the background of my site that I want to play all the time and not start over every time a link is clicked.

The whole thing works pretty good, except for 2 issues I'm having.

1. Let's say I click the contact us link. I would now see #contactus at the end of the url. If I then refresh the page, I see my home page content again.
2. Same problem if I try linking someone to my contact us page.

I was wondering if jQuery can somehow find out what comes after the # sign in the url. In that case, I can change the last line of my jQuery code to load that instead of the home data all the time.

window.location.hash will contain the value after the hash (if there is one). (This is when there's a hash in the current url, eg. current page, in the browser's address bar.)

Otherwise, if you're reading a link from an href, you'll need to use indexOf('#') and a bit of parsing.

Thanks for your answers guys. This is how I did it now:

$(document).ready(function() {

    var content_loader = $('#content-loader');

    $('#nav ul li a').click(function () {
        $(this).closest('ul').find('li.active').removeClass('active');
        $(this).parent().addClass('active');
        content_loader.load('content/' + $(this).attr('href').slice(1) + '.html');  
        });

    var initial = 'home';
    if (window.location.hash) {
        initial = window.location.hash.slice(1);
        }

    $('#nav').find('a[href="#' + initial + '"]').parent('li').addClass('active');
    content_loader.load('content/' + initial + '.html');

    });
