Bootstrap Navbar Dropdown on Hover if not mobile

I am trying to make bootstrap dropdown from navbar appear on hover, but stop hover effect when minimized (mobile). This is what I mean, but when I add an if statement, the whole effect fails: HTML:

  <nav class="navbar navbar-default navbar-fixed-top">
    <div class="container">
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand vaos" href="../index.html">VAOS</a>
      </div>
      <div id="navbar" class="collapse navbar-collapse navbar-right">
        <ul class="nav navbar-nav">
          <li class="active"><a class="trans" href="../index.html">Home</a></li>
          <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">What is VAOS <span class="caret"></span></a>
            <ul class="dropdown-menu" role="menu">
              <li><a href="options.html">VAOS & Other Options</a></li>
              <li><a href="candidate.html">Am I a Candidate</a></li>
              <li><a href="surgeon.html">Find a Surgeon</a></li>
              <li><div class="ArrowUp1"></div></li>
            </ul>
         </li>

          <li><a href="experience.html">Testimonials</a></li>
          <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Resources <span class="caret"></span></a>
            <ul class="dropdown-menu" role="menu">
              <li><a href="clinical-support.html">Clinical Support</a></li>
              <li><a href="videos.html">Procedural Videos</a></li>
              <li><a href="resources.html">Other Links & Resources</a></li>
              <li><div class="ArrowUp2"></div></li>
            </ul>
          </li>
        </ul>
      </div><!--/.nav-collapse -->
    </div>

      

        
        
        
      

    

CSS:

@media (min-width: 768px) {
  .navbar-nav .open ul {
    display: none;
  }
  .navbar-default .navbar-nav > .open > a,
  .navbar-default .navbar-nav > .open > a:hover,
  .navbar-default .navbar-nav > .open > a:focus {
    color: #555;
    background: none;
  }
  .navbar-default .navbar-nav > li:hover {
    background: #e7e7e7;
  }
  .navbar-inverse .navbar-nav > .open > a,
  .navbar-inverse .navbar-nav > .open > a:hover,
  .navbar-inverse .navbar-nav > .open > a:focus {
    color: #969696;
    background: none;
  }
  .navbar-nav > li:hover {
    background: transparent !important;
  }
  .navbar-nav .hovernav:hover > .dropdown-menu {
    display: block;
  }
}

      

        
        
        
      

    

JavaScript:

'use strict';

$('ul.nav li.dropdown').hover(function() {
  if(window.width > 767) {
    $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
    $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
  }   
});
