Active side menu on "INSPINIA" admin theme

I want to highlight the active page on the side bar menu using JavaScript. I am using INSPINIA theme.

I've tried using JavaScript and it's working fine for normal menus. But it's not working for submenus. I want to display in class instead of active class for submenus. Please check my code and help me.

HTML

<nav class="navbar-default navbar-static-side" role="navigation">
   <div class="sidebar-collapse">
      <ul class="nav metismenu" id="side-menu">
         <li>
            <a href="dashboard.html"><i class="fa fa-th-large"></i><span class="nav-label">Dashboards</span></a>
         </li>
         <li>
            <a href="#"><i class="fa fa-building"></i><span class="nav-label">Company</span><span class="fa arrow"></span></a>
            <ul class="nav nav-second-level collapse">
               <li><a href="addcompany.html">Add Company</a></li>
               <li><a href="#">View Company</a></li>
            </ul>
         </li>
         <li>
            <a href="mailbox.html"><i class="fa fa-envelope"></i><span class="nav-label">Person</span><span class="fa arrow"></span></a>
            <ul class="nav nav-second-level collapse">
               <li><a href="addperson.html">Add Person</a></li>
               <li><a href="#">View Person</a></li>
            </ul>
         </li>
      </ul>
   </div>
</nav>

JavaScript

$(document).ready(function () {
    var url = window.location;
    // for sidebar menu but not for metismenu submenu
    $('ul.metismenu a').filter(function () {
        return this.href == url;
    }).parent().siblings().removeClass('active').end().addClass('active');
    // for metismenu which is like a submenu
    $('ul.nav-second-level a').filter(function () {
        return this.href == url;
    }).parentsUntil(".metismenu > .nav-second-level").siblings().removeClass('active').end().addClass('active');
});

Expected output

<li class="active">
   <a href="#"><i class="fa fa-building"></i><span class="nav-label">Company</span><span class="fa arrow"></span></a>
   <ul class="nav nav-second-level collapse in">
      <li><a href="addcompany.html">Add Company</a></li>
      <li><a href="#">View Company</a></li>
   </ul>
</li>

Actual Output

<li class="active">
   <a href="#"><i class="fa fa-building"></i><span class="nav-label">Company</span><span class="fa arrow"></span></a>
   <ul class="nav nav-second-level collapse active">
      <li><a href="addcompany.html">Add Company</a></li>
      <li><a href="#">View Company</a></li>
   </ul>
</li>

I found the answer.

$(function() {
    setNavigation();
});

function setNavigation() {
    var path = window.location.pathname;
    path = path[0] == '/' ? path.substr(1) : path; //it will remove the dash in the URL

    $("ul.metismenu a").each(function() {
        var href = $(this).attr('href');
        if (path.substring(0, href.length) === href) {
            $(this).closest('li').addClass('active');
        }
    });

    $("ul.metismenu .nav-second-level a").each(function() {
        var href = $(this).attr('href');
        if (path.substring(0, href.length) === href) {
            $(this).parent().parent().closest('li').addClass('active');
            $(this).closest('ul').addClass('in');
        }
    });
}
