javascript - Bootstrap 轮播并显示多个元素

Question

我正在使用@paulalexandru( https://stackoverflow.com/users/3522687/paulalexandru ) 解决方案在 Bootstrap slider 上显示多个元素。不幸的是，我的 javascript 不够先进，无法显示 4 个元素(或更多或更少)，而不是当前的 3 个。有人可以分解以下代码，这样我就可以理解从哪里开始理解脚本的内容一次只显示 3 个？这是 Paul 作品的一个功能正常的 JS fiddle 。 http://fiddle.jshell.net/paulalexandru/at606jpe/light/

我对 CSS 的理解还不错，但我知道轮播并不仅仅依赖于 CSS 在这里显示。我试图让它根据屏幕尺寸显示 x 个元素

Answer 1

我改变了所有:

• 33% 到 25%。
• col-md-4 到 col-md-3

结果如下:

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

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

    if (next.next().length>0) {
        next.next().children(':first-child').clone().appendTo($(this));
    }
    else {
        $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
    }
});

.carousel-inner .active.left  { left: -25%;             }
.carousel-inner .active.right { left: 25%;              }
.carousel-inner .next         { left: 25%               }
.carousel-inner .prev         { left: -25%              }
.carousel-control.left        { background-image: none; }
.carousel-control.right       { background-image: none; }
.carousel-inner .item         { background: white;      }
