javascript - 传送带上每个四个项目不工作

Question

当我在本地文件中尝试以下代码时，我无法正确获取它，请参阅代码笔 4 items per Carousel 。我已在问题中插入了代码。请看下面

我只想为每个轮播制作 4 个项目，单击“下一步”，应添加一个项目

请看下面的代码，我需要它是水平的而不是垂直的

$(document).ready(function(){

$('#recipeCarousel').carousel({
  interval: 10000
})

$('.carousel .carousel-item').each(function(){
    var next = $(this).next();
    if (!next.length) {
    next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));
    
    for (var i=0;i<2;i++) {
        next=next.next();
        if (!next.length) {
        	next = $(this).siblings(':first');
      	}
        
        next.children(':first-child').clone().appendTo($(this));
      }
});

})

.carousel-inner .carousel-item-right.active,
.carousel-inner .carousel-item-next {
  transform: translateX(25%);
}

.carousel-inner .carousel-item-left.active, 
.carousel-inner .carousel-item-prev {
  transform: translateX(-25%)
}
  
.carousel-inner .carousel-item-right,
.carousel-inner .carousel-item-left{ 
  transform: translateX(0);
}
