javascript - 图像在轮播中组合

Question

图像在轮播中组合。我用 html 写成

$(function(){
    $('#carousel').each(function(){
        var slideTime = 200;
        var delayTime = 2000;

        var carouselWidth = $(this).width();
        var carouselHeight = $(this).height();
        $(this).append('<div id="carousel_prev"></div><div id="carousel_next"></div>');
        $(this).children('ul').wrapAll('<div id="carousel_wrap"><div id="carousel_move"></div></div>');

        $('#carousel_wrap').css({
            width: (carouselWidth),
            height: (carouselHeight),
            position: 'relative',
            overflow: 'hidden'
        });

        var listWidth = parseInt($('#carousel_move').children('ul').children('li').css('width'));
        var listCount = $('#carousel_move').children('ul').children('li').length;

        var ulWidth = (listWidth)*(listCount);

        $('#carousel_move').css({
            top: '0',
            left: -(ulWidth),
            width: ((ulWidth)*3),
            height: (carouselHeight),
            position: 'absolute'
        });

        $('#carousel_wrap ul').css({
            width: (ulWidth),
            float: 'left'
        });
        $('#carousel_wrap ul').each(function(){
            $(this).clone().prependTo('#carousel_move');
            $(this).clone().appendTo('#carousel_move');
        });

        carouselPosition();

        $('#carousel_prev').click(function(){
            clearInterval(setTimer);
            $('#carousel_move:not(:animated)').animate({left: '+=' + (listWidth)},slideTime,function(){
                carouselPosition();
            });
            timer();
        });

        $('#carousel_next').click(function(){
            clearInterval(setTimer);
            $('#carousel_move:not(:animated)').animate({left: '-=' + (listWidth)},slideTime,function(){
                carouselPosition();
            });
            timer();
        });

        function carouselPosition(){
            var ulLeft = parseInt($('#carousel_move').css('left'));
            var maskWidth = (carouselWidth) - ((listWidth)*(listCount));
            if(ulLeft == ((-(ulWidth))*2) || ulLeft == ((-(ulWidth))*2)+1) {
                $('#carousel_move').css({left:-(ulWidth)});
            } else if(ulLeft == 0) {
                $('#carousel_move').css({left:-(ulWidth)});
            };
        };

        timer();

        function timer() {
            setTimer = setInterval(function(){
                $('#carousel_next').click();
            },delayTime);
        };

    });
});

    <li><a href="#"><img src="photo2.jpg" alt=""></a></li>
  </ul>
</div>

<script src="carousel.js"></script>

但是现在当我运行我的网站时，就像

我想制作一个旋转木马，首先显示 photo1，其次显示 photo2，然后再次显示下一张 photo1 ...。但现在首先『photo1 和 photo2 同时显示』其次』它们同时再次显示，接下来它们又是...。为什么我的代码是错误的？我应该如何解决这个问题？我想把 carousel 放在浏览器剩余的区域中，并且 carousel 的图像大小在该区域调整 100%。

我不知道你为什么有这么多代码，如果你使用的是 Bootstrap ，你可以使用你的轮播，这里有一个简单明了的例子。

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Carousel Example</h2>  
  <div id="myCarousel" class="carousel slide" data-ride="carousel">
    <!-- Indicators -->
    <ol class="carousel-indicators">
      <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
      <li data-target="#myCarousel" data-slide-to="1"></li>
      <li data-target="#myCarousel" data-slide-to="2"></li>
    </ol>

    <!-- Wrapper for slides -->
    <div class="carousel-inner">
      <div class="item active">
        <img src="https://placeimg.com/640/480/arch" alt="Arch" style="width:100%;">
      </div>

      <div class="item">
        <img src="https://placeimg.com/640/480/nature" alt="Nature" style="width:100%;">

        <img src="https://placeimg.com/640/480/tech" alt="Tech" style="width:100%;">
      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" data-slide="next">
