Question

我正在使用自举媒体滑块轮播。但是，如果项目小于4，则重复项目。我想每次点击一个项目。

请参阅下面的代码

JQUERY

    $(document).ready(function(){
          $('#media').carousel({
            pause: true,
            interval: false
          });
          $('.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));
            }
          });
     });

已经尝试改变[for（var i = 0; i＆lt; 2; i ++）{] i＆lt; 4＆i＆lt; 6而不是i＆lt; 2

CSS：

/* carousel */
    .carousel-pack{height:40px; margin:0; padding:0;}
    .carousel-pack-inner{width:252px; margin: 0 auto;}
    .media-carousel 
    {
      margin-bottom: 0;
      margin-top: 20px;
    }
    .carousel-control{line-height: 24px;}
    /* Previous button  */
    .media-carousel .carousel-control.left 
    {
        left: -37px;
        background-image: none;
        background: none repeat scroll 0 0 #222222;
        border: 2px solid #FFFFFF;
        height: 32px;
        width: 32px;
        margin-top: 4px;
    }
    /* Next button  */
    .media-carousel .carousel-control.right 
    {
        right: -37px;
        background-image: none;
        background: none repeat scroll 0 0 #222222;
        border: 2px solid #FFFFFF;
        height: 32px;
        width: 32px;
        margin-top: 4px;
    }
    /* Changes the position of the indicators */
    .media-carousel .carousel-indicators 
    {
      right: 50%;
      top: auto;
      bottom: 0px;
      margin-right: -19px;
    }
    /* Changes the colour of the indicators */
    .media-carousel .carousel-indicators li 
    {
      background: #c0c0c0;
    }
    .media-carousel .carousel-indicators .active 
    {
      background: #333333;
    }
    .thumbnail
    {
      width: 48px !important;
      height: 40px!important;
      border-radius:0;
      border-radius: 8px !important;
    }
    .thumbs{
        margin-right: 15px;
        padding: 0;
        float: left;
    }
    .thumbs:first-child{margin-left: 7px;}
    .thumbs:last-child{margin-right: 7px;}

通过使用 array_chunk（）和 foreach 将数组拆分为块来解决此问题。

<强> HTML

 <div class="carousel-pack">
   <div class="carousel-pack-inner">
     <div class="carousel slide media-carousel" data-ride="carousel" data-wrap="true" id="media">
       <div class="carousel-inner">
         <?php 
           $active = 'active';

            $pages = array_chunk($file_array,3);

            foreach ($pages as $key => $data) { ?>
              <div class="item <?php echo $active; ?>">
                 <?php foreach ($data as $key => $value) { ?>
                   <div class="row-new">
                     <div class="thumbs">
                        <a class="thumbnail" href="#" target="_blank"><?php echo $value; ?></a>
                     </div>
