Question

您好我正在尝试制作一个可以一次滑动一个项目的多项目引导程序轮播。正是这个bootply正在做什么。 http://www.bootply.com/94452 当我复制粘贴代码在编辑器中，当然链接jquery和bootstrap cdn时，轮播不会逐项滑动。

知道为什么吗？这是我的HTML：

CSS：

.carousel-inner .active.left { left: -25%; }
.carousel-inner .next        { left:  25%; }
.carousel-inner .prev        { left: -25%; }
.carousel-control            { width:  4%; }
.carousel-control.left,.carousel-control.right {margin-left:15px;background-image:none;}

JS：

$('#myCarousel').carousel({
  interval: 4000
})

$('.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));
  }
});

代码与Bootply中显示的相同，除了html中的bootstrap和jquery cdn和stylesheet链接。

为什么它只适用于Bootply？

我终于想出了如何让旋转木马在普通浏览器上一次滑动一个项目。

1）从html文件中删除＆＃34; slide＆＃34;来自，所以它只是。这将阻止bootstrap的默认轮播幻灯片

2）包括来自https://daneden.github.io/animate.css/的animate.css。 <link rel="stylesheet" href="animate.css">这将为您提供许多很酷的动画效果来定制您的轮播。 3）在css文件中添加：

.item {
  animation-name: slideInRight;
  animation-duration: 1s;
}

4）在animate.css文件中，将transform：translate3d（100％，0,0）更改为25％

你可以从animate.css中选择你想要的任何动画效果！

CSS：

.carousel-inner .active.left { left: -25%; }
.carousel-inner .next        { left:  25%; }
.carousel-inner .prev        { left: -25%; }

.carousel-control            { width:  4%; }

JS：

$(document).ready(function(){
$('#myCarousel').carousel({
  interval: 2000

});

$(document).ready(function(){
  $('.carousel .item').each(function(){
    var next = $(this).next();
    if (!next.length) {
      next = $(this).siblings(':first');

        next = $(this).siblings(':first');
        }

      next.children(':first-child').clone().appendTo($(this));
    }
  });
});

animate.css：

将现有代码更改为：

@-webkit-keyframes slideInRight {
  from {
    -webkit-transform: translate3d(25%, 0, 0);
    transform: translate3d(25%, 0, 0);
    visibility: visible;
  }

  to {
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
  }
}

@keyframes slideInRight {
  from {
    -webkit-transform: translate3d(25%, 0, 0);
    transform: translate3d(25%, 0, 0);
    visibility: visible;
  }

  to {
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
  }
}

.slideInRight {
  -webkit-animation-name: slideInRight;
  animation-name: slideInRight;
}

看起来BootstrapJS CDN出现了问题。我在Chrome中看到了这个错误：

无法在资源“https://maxcdn.bootstrapcdn.com/bootstrap/3.1.0/js/bootstrap.min.js”的“完整性”属性中找到有效的摘要，其中包含计算出的SHA-256完整性'A783Hjykc5z + a + ph8BJrfLuU5HE + lwZR + azVrLPZ45k ='。资源已被阻止。

因此它不知道$（...）。carousel在test.js中是什么。从CDN尝试最新版本的Bootstrap：

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>

bootstrap multi item carousel在bootply上工作但在浏览器上不工作
