javascript - jQuery: Why can't my script remove the class? -


jquery won't remove class after scrolling

this script:

$(window).scroll(function(){     if($(window).scrolltop() >= $("#white").offset().top -70) {         $('.burger-menu').addclass('white');     } else {         $('.burger-menu').removeclass('white');     } });  $(window).scroll(function(){     if($(window).scrolltop() >= $("#color-main").offset().top -70) {         $('.burger-menu').addclass('color-main');     } else {         $('.burger-menu').removeclass('color-main');     } });  $(window).scroll(function(){     if($(window).scrolltop() >= $("#yellow").offset().top -70) {         $('.burger-menu').addclass('yellow');     } else {         $('.burger-menu').removeclass('yellow');     } });

this html:

<section class="home-page" id="white">blablabla</section> <section class="wrap" id="color-main">blablabla</section> <section class="wrap" id="yellow">blablabla</section>

but <div>

<div class="burger-menu white color-main yellow">

still has classes "white" , "color-main", should removed. :(

i made codepen see it.

there 2 fixes recommed try:

  1. don't multiple .scroll(function(){...}) calls, overwrite each other.
  2. use $("body").scroll(function(){...}), because that's element (usally) scroll in
