Wordpress change active class on bootstrap nav while hovering

Question

I'm building a website using Wordpress. Most of the nav menu links, link to an id on the homepage. So when I load my site all the links that link to a place on the homepage are currently active. I removed the script in Wordpress that checks to see if its active. I figured I could use bootstrap scrollspy to get this done or even this JSFiddle https://jsfiddle.net/cse_tushar/Dxtyu/141/

The problem I'm having is since the navigation is being spit out by Wordpress I don't have the ability to go in and actually hard code "active" to the first li element and then do a add class and remove class. How would I alter the above JSFiddle so it does a hash target. So whenever I scroll and hit a div with the same ID as a nav item it triggers the active class and stays active until I hit another one or change pages. Here is what my nav looks like on wordpress.

<nav class="collapse navbar-collapse" role="navigation">
        <ul id="menu-primary-navigation" class="nav navbar-nav">
            <li class="current-menu-item current_page_item menu-about"><a href="/#about">About</a></li>
            <li class="current-menu-item current_page_item menu-team"><a href="/#team">Team</a></li>
            <li class="current-menu-item current_page_item menu-services"><a href="/#services">Services</a></li>
            <li class="menu-services"><a href="/blog">Blog</a></li>
            <li class="current-menu-item current_page_item menu-contact-us"><a href="/#contact">Contact Us</a></li>
        </ul>      
</nav>  

<div id="about">
    Something Here
</div>

<div id="team">
    Something Here
</div>

You can accomplish that by adding the following line at the beginning of page load:

$("ul li a:first").addClass('active');

$(document).ready(function () {
    $(document).on("scroll", onScroll);
    $("ul li a:first").addClass('active');
    
    //smoothscroll
    $('a[href^="#"]').on('click', function (e) {
        e.preventDefault();
        $(document).off("scroll");
        
        $('a').each(function () {
            $(this).removeClass('active');
        })
        $(this).addClass('active');
      
        var target = this.hash,
            menu = target;
        $target = $(target);
        $('html, body').stop().animate({
            'scrollTop': $target.offset().top+2
        }, 500, 'swing', function () {
            window.location.hash = target;
            $(document).on("scroll", onScroll);
        });
    });
});

function onScroll(event){
    var scrollPos = $(document).scrollTop();
    $('#menu-center a').each(function () {
        var currLink = $(this);
        var refElement = $(currLink.attr("href"));
        if (refElement.position().top <= scrollPos && refElement.position().top + refElement.height() > scrollPos) {
            $('#menu-center ul li a').removeClass("active");
            currLink.addClass("active");
        }
        else{
            currLink.removeClass("active");
        }
    });
}
