bootstrap导航菜单做active判断

  <div class="container">
        <ul class="nav nav-pills">
            <li><a href="index.html">Home</a></li>
            <li><a href="about.html">About</a></li>
        </ul>
        <h1>Home Page</h1>
    </div>

 $(‘.nav-pills‘).find(‘a‘).each(function () {
            if (this.href == document.location.href || document.location.href.search(this.href) >= 0) {
                $(this).parent().addClass(‘active‘); // this.className = ‘active‘;
            }
        });
