How to Active nav bar in bootstrap with jquery

Question

I want make the navbar active when i click it,,

Here is the jquery i use

$(document).ready(function () {
        $('.navbar li').click(function(e) {
            $('.navbar li').removeClass('active');
            var $this = $(this);
            if (!$this.hasClass('active')) {
                $this.addClass('active');
            }
        e.preventDefault();
        });         
    });

But because the preventDefault i can't go to the link that i want. It just make the navbar active, but it's not go to the link that i choose.

And here is the link code :

<div class="nav-collapse collapse">
    <ul class="nav">
        <li><a href='<?php echo site_url(' tampilan ') ?>'>Knowledge Base</a>
        </li>
        <li><a href='<?php echo site_url(' ticketing/browse_ticketing ') ?>'>Ticketing</a>
        </li>
        <li><a href='<?php echo site_url(' user/logout ') ?>'>Logout</a>
        </li>
    </ul>
</div> 

if i dont use preventDefault() the navbar won't active, but if i use it i can't go to the link i want..

Solution

Change the jQuery script to this:

<script type="text/javascript">
    $(document).ready(function () {
        var url = window.location;
        $('ul.nav a[href="'+ url +'"]').parent().addClass('active');
        $('ul.nav a').filter(function() {
             return this.href == url;
        }).parent().addClass('active');
    });
</script>
