Navbar not staying fixed

Question

Hi guys I am trying to follow this Example and do exactly the same for my site, however I cant get my nav bar to work and follow the screen down. I have tried a lot and not sure what is going on.

}
.navbar-inverse .navbar-collapse,
.navbar-inverse .navbar-form {
    border-color: transparent;
}
    
    .section{
        background-color:Red;
        height: 1000px;
        margin: 0;
    }
    
    .section h1 {
        margin: 0;
    }
    
    .section2{
        background-color:blue;
        height: 1000px;
            margin: 0;
    }
    
    .section3{
        background-color:Black;
        height: 1000px;
            margin: 0;
    }

If I change var navHeight = $( window ).height() - 70; to 277 it works fine however if I make the screen smaller it snaps straight up without waiting so its really weird.

Any help on this matter would be great.

Thanks

Apologies. I tried to fix your code instead of giving you a different solution. This works without the jumping.

var $window = $(window),
        $el = $('nav'),
        elTop = $el.offset().top;

      $window.scroll(function() {
        $el.toggleClass('navbar-fixed-top', $window.scrollTop() > elTop);
      });
