Using twitter bootstrap, and I need to initiate active class to the li portion of the main nav. Automagically. We use php not ruby.
Sample nav :
<ul class="nav">
    <li><a href="/">Home</a></li>
    <li><a href="/forums">Forums</a></li>
    <li><a href="/blog">Blog</a></li>
    <li><a href="/faqs.php">FAQ's</a></li>
    <li><a href="/item.php">Item</a></li>
    <li><a href="/create.php">Create</a></li>
</ul>
Bootstrap code is as follows:
<li class="active"><a href="/">Home</a></li>
So just need to figure out how to append the class active to the current page. Have looked thru nearly every answer on Stack, with no real joy.
I had played with this:
/*menu handler*/
$(function(){
    var url = window.location.pathname;  
    var activePage = url.substring(url.lastIndexOf('/')+1);
    $('.nav li a').each(function(){  
        var currentPage = this.href.substring(this.href.lastIndexOf('/')+1);
        if (activePage == currentPage) {
            $(this).parent().addClass('active'); 
        } 
    });
})
But no joy.
