I know this post is old but use

    $(document).ready(function () {

    var url = window.location;
    $('ul.nav li a').each(function () {
        if (this.href == url) {
            $("ul.nav li").each(function () {
                if ($(this).hasClass("active")) {
                    $(this).removeClass("active");
                }
            });
            $(this).parents().addClass('active');
        }

    });

});

Since you also wants to active the all the parents.

Actually Reynaldo, almost had it... At least for me, this works pretty good, on activing the current option and deactiving the previous one, based on his example.

$(document).ready(function() {
    var url = window.location;                
    $('ul.nav li a').each(function () {
         if (this.href == url) {
              $("ul.nav li").each(function () {
                   if ($(this).hasClass("active")) {
                        $(this).removeClass("active");
                   }
              });
              $(this).parent().addClass('active');
         }
    });
});

I have created a sample which full fill your requirement you need to modify the code according to your need. Use this jquery on master page

 <script type="text/javascript">
        $(function () {
            $('[id*=submenu]').addClass('sub-menu open');
            $('[id*=Master_Pages]').attr("aria-expanded", true);

            $('.subMenus').click(function () {
                localStorage.setItem('lastTab', $(this).attr('id'));
            });
        });
        function pageLoad() {
            var isActiveLink = false;
            $.each($('.subMenus'), function () {
                if ($(this).attr('id') == localStorage.getItem('lastTab')) {
                    $(this).closest('li').addClass('active');
                    localStorage.removeItem('lastTab');
                    isActiveLink = true;
                }
                else {
                    $(this).closest('li').removeClass('active');
                }
            });
            if (!isActiveLink) {
                $('[id*=Master_Designation]').closest('li').addClass('active');
            }
        }
    </script>

Use this:

<div class="navbar">
    <div class="navbar-inner">
        <div class="container">
            <ul class="nav">
                <li class="active"><a href="/Default.aspx">Default</a></li>
                <li><a href="/Clients.aspx">Clients</a></li>
                <li><a href="/_display/">Display</a></li>
            </ul>
        </div>
    </div>
</div>

$(document).ready(function () {
        var url = window.location;
        $('.navbar .nav').find('.active').removeClass('active');
        $('.navbar .nav li a').each(function () {
            if (this.href == url) {
                $(this).parent().addClass('active');
            }
        }); 
    });

Example: http://jsfiddle.net/yUdZx/3/

And, in the "href" use "Page.ResolveUrl"

<a href="<%= Page.ResolveUrl("~/Clients.aspx") %>">Clients</a>

It's better...

following code works if I have subpages:

 $(document).ready(function () {

        $('.navbar .nav').find('.active').removeClass('active');

        var url = window.location.toString();
        var u = url.substring(0, url.lastIndexOf("/")).toString();

        $('.navbar .nav li a').each(function () {

            var hr = this.href.substring(0, this.href.lastIndexOf('/')).toString();

            if ((u == hr) || (u.indexOf(hr) > -1))
            {
                $(this).parent().addClass('active');
                return false;
            }
        });
        // Deactivation to manually add items you have with href = "#" example:
        $('#liSalir').removeClass('active');
});

I've placed this in each one of my content pages, changing the id of the nav item for each page (this uses JQuery selectors). So for this to work for you you'll need to give your list items an Id. I don't add the "active" class to the master page because all we need to do is highlight the appropriate one when the content loads.

<script language="javascript" type="text/javascript">
    $(document).ready(function () {
        $("[id$=yourNavItemId]").addClass("active");
    });
</script>

Note: if you're using ASP.NET controls instead of list items inside of your nav bar, they might be getting prefixed at runtime causing your javascript not to find the Id you think you're looking for.
