目标 - 我想在滚动一下后实现向下滑动（对于导航栏）效果。我实际上达到了我想要的，但我遇到了问题。如何在导航菜单中实现平滑滑下效果
问题 - 滚动到顶部时，导航栏变得粘滞而没有任何效果，它有种魅力。任何人都可以帮我解决这个问题吗？
你可以在这里看到我的代码Codepen。
// Sticky Header
$(window).scroll(function() {
if ($(window).scrollTop() > 100) {
$('#header').addClass('sticky-header');
$('#header .mo-row').removeClass('sticky-border');
} else {
$('#header').removeClass('sticky-header');
$('#header .mo-row').addClass('sticky-border');
}
});
var sidebarBox = document.querySelector('#box');
var sidebarBtn = document.querySelector('#btn');
var pageWrapper = document.querySelector('#main-content');
sidebarBtn.addEventListener('click', function(event) {
if (this.classList.contains('active')) {
this.classList.remove('active');
sidebarBox.classList.remove('active');
} else {
this.classList.add('active');
sidebarBox.classList.add('active');
}
});
// accordion js
$(document).ready(function() {
function close_accordion_section() {
$('.accordion .accordion-section-title').removeClass('active2');
$('.accordion .accordion-section-content').slideUp(300).removeClass('open');
}
$('.accordion-section-title').click(function(e) {
// Grab current anchor value
var currentAttrValue = $(this).attr('href');
if($(e.target).is('.active2')) {
close_accordion_section();
}else {
close_accordion_section();
// Add active class to section title
$(this).addClass('active2');
// Open up the hidden content panel
$('.accordion ' + currentAttrValue).slideDown(300).addClass('open');
}
e.preventDefault();
});

好了，我们不能，实际上，你的链接无法正常工作。而且在实际问题中也需要发布代码。 – Roberrrt
我已更新链接@Roberrrt –
因此，您希望导航栏在滚动时滑入？ – Roberrrt
