There you can see, that it somehow does not work. BUT I don't get any errors in my console. So I am left clueless.
你可以看到，它在某种程度上不起作用。但是我的控制台没有任何错误。所以我变得毫无头绪。
Does anyone know why it does not work with bootstrap 4 and what I would need to change?
有人知道为什么它不能使用bootstrap 4吗?我需要改变什么?

在Bootstrap4 carousel中，代码中有一个小的更改。所有的旋转木马项目类都应该从项目改为旋转木马项目。看一下代码
<div class="item">
should changed to
应该更改为
<div class="carousel-item">
$(document).ready( function() {
$('#myCarousel').carousel({
interval: 4000
});
var clickEvent = false;
$('#myCarousel').on('click', '.nav a', function() {
clickEvent = true;
$('.nav li').removeClass('active');
$(this).parent().addClass('active');
}).on('slid.bs.carousel', function(e) {
if(!clickEvent) {
var count = $('.nav').children().length -1;
var current = $('.nav li.active');
current.removeClass('active').next().addClass('active');
var id = parseInt(current.data('slide-to'));
if(count == id) {
$('.nav li').first().addClass('active');

}
clickEvent = false;
});
});body { padding-top: 20px; }
