我只想在无限轮播中一次滚动一个 Logo 。下面是我的代码。任何帮助，将不胜感激。我尝试将 singleWidth 定义为 190px，这是 Logo 的大小。尽管我仍然想念如何在末尾划分负空间以创建循环效果。

      <html>
      <head>
      <style type="text/css" media="screen">
      .infiniteCarousel {
      position: relative;
      width: 1354px;
      }

      .infiniteCarousel .carousel_wrapper {
      width: 1354px;
      overflow: auto;
      height: 162px;
      margin: 0 auto;
      top: 0;
      }

      .infiniteCarousel ._carousel_wrapper ul {
      width: 1252px; /* single item * n */
      list-style-image:none;
      list-style-position:outside;
      list-style-type:none;
      margin:0;
      padding:0;
      top: 0;
      }

      .infiniteCarousel ul li {
      display:block;
      float:left;
      padding: 10px;
      height: 162px;
      width: 190px;
      }

      .infiniteCarousel .arrow {
      display: block;
      height: 18px;
      width: 19px;
      background: url(hospitality_img/right_arrow.png) no-repeat 0 0;
      text-indent: -999px;
      position: absolute;
      top: 100px;
      cursor: pointer;
      outline: 0;
      right: 0;
      }

      .infiniteCarousel .forward {
      background-position: 0 0;
      right: 0;
      }

      .infiniteCarousel .back {
      display: block;
      height: 18px;
      width: 19px;
      background: url(hospitality_img/left_arrow.png) no-repeat 0 0;
      text-indent: -999px;
      position: absolute;
      top: 100px;
      cursor: pointer;
      outline: 0;
      left: 0;
      }
      </style>

最佳答案

好吧，我花了几个小时研究代码，它似乎是为了同时获取所有图标并在屏幕上运行它们而编写的。我试图修改代码以只抓取一个图标，但这是一个非常丑陋的拼凑。所以我重新编写了代码，您可以在 div 中放置任意数量的图标，更改它在屏幕上花费的时间并随时停止。

这是 FIDDLE .

它可能不适合你，但它很有趣而且我学到了很多东西。

JS

var divwidth = $('.sliderdiv').width();
var firstmove = (divwidth * 0.5);
var firsttime = 600;
var lagtime = 1200;
var secondmove = (divwidth * 0.5)-50;
var secondtime = 600;
var numberimg = $('.holder img').length;
var n = 0;
animate( n );

$('#stopme').click(function(){
      $( '.sliderdiv img' ).stop(true);
});

function animate( n )
{
  var $moveimage = $('.holder img');
  $( $moveimage[n] ).clone().appendTo('.sliderdiv');
  var $slideimage = $('.sliderdiv img');  
  $( $slideimage ).animate(
                     { left: '+=' + firstmove }, firsttime,
             function() {
                         $( $slideimage ).animate(
                                            { left: '+=1' }, 
                                             lagtime,
             function() {
                         $( $slideimage ).animate(
                                            { left: '+=' + secondmove }, 
                                            secondtime,
             function()  {
                           $('.sliderdiv').html('');
                           n = n + 1;
                           if(n > numberimg - 1){ n = 0; }
                           animate( n );
                          }
                                             );}
                                             );}
                      );
}
