Toggle the Bootstrap navbar class based on the current scroll position

I'm currently working on the development of a website that includes a feature where a static navbar transforms into a fixed navbar after scrolling down 500px. The transition from "navbar-static-top" to "navbar-fixed-top" is functioning properly. However, I am looking for assistance in implementing a functionality that changes the navbar back to static when the user scrolls back to the top of the page. I have searched online for solutions and attempted to use the jQuery 'hasClass()' function without success. Do you have any suggestions or ideas on how to achieve this?

This is the current code snippet that I am working with:

   $(window).scroll(function() {
    $('#navbarMain').each(function(){
    var imagePos = $(this).offset().top;

    var topOfWindow = $(window).scrollTop();

        if (imagePos > topOfWindow-500) {
            $(this).removeClass("navbar-static-top");
            $(this).addClass("navbar-fixed-top");
        }

    });
});

Answer №1

i have implemented the following code snippet in my project:

$(window).scroll(function() {
    var nav = $('#navbarMain');
    var top = 200;
    if ($(window).scrollTop() >= top) {

        nav.addClass('fixed');

    } else {
        nav.removeClass('fixed');
    }
});

Answer №2

let navTop = $('#navbarMain').offset().top + $('#navbarMain').height();

$(window).on('scroll',function(){ 
  let stopPosition = Math.round($(window).scrollTop()); 
  if (stopPosition > navTop) { 
     $('.navbar-static-top').addClass('navbar-fixed-top'); 
  } else { 
     $('.navbar-static-top').removeClass('navbar-fixed-top'); 
  } 
});

Answer №3

Have you attempted modifying the classes within an else statement once more? Perhaps something along these lines will resolve the issue:

if (imagePos > topOfWindow-500) {
    $(this).removeClass("navbar-static-top");
    $(this).addClass("navbar-fixed-top");
} else {
    $(this).addClass("navbar-static-top");
    $(this).removeClass("navbar-fixed-top");
}
