How to achieve seamless left and right sliding switching effect of images in JavaScript while limiting them to the container?

<div id="container">
  <ul id="imageList">
    <li><img src="image1.jpg"/></li>
    <li><img src="image2.jpg"/></li>
    <li><img src="image3.jpg"/></li>
    ...
  </ul>
</div>

var container = document.getElementById('container');
var imageList = document.getElementById('imageList');
var images = imageList.getElementsByTagName('img');
var currentIndex = 0; // 当前显示的图片索引

// 设置imageList的宽度，保证所有图片水平排列
imageList.style.width = images.length * 100 + '%';

// 设置每张图片的宽度
for (var i = 0; i < images.length; i++) {
  images[i].style.width = 100 / images.length + '%';
}

function slideTo(index) {
  // 计算需要滑动的距离
  var distance = -index * container.offsetWidth;

  // 设置imageList的动画效果
  imageList.style.transition = 'transform 0.5s ease';
  imageList.style.transform = 'translate(' + distance + 'px, 0)';
}

function reset() {
  // 当滑动到最后一张图时，切换到第一张图
  if (currentIndex === images.length) {
    currentIndex = 0;
  }

  // 当滑动到第一张图之前时，切换到最后一张图
  if (currentIndex < 0) {
    currentIndex = images.length - 1;
  }

  // 移除过渡效果，快速切换到目标位置
  imageList.style.transition = 'none';
  imageList.style.transform = 'translate(' + (-currentIndex * container.offsetWidth) + 'px, 0)';
}

function slideNext() {
  currentIndex++;
  slideTo(currentIndex);
}

function slidePrev() {
  currentIndex--;
  slideTo(currentIndex);
}

// 监听容器的滑动事件
container.addEventListener('touchstart', function (event) {
  var startTouchPos = event.touches[0].clientX;
  var lastTouchPos = startTouchPos;

  // 监听容器的滑动过程
  container.addEventListener('touchmove', function (event) {
    var currentTouchPos = event.touches[0].clientX;
    var diff = currentTouchPos - lastTouchPos;

    // 判断滑动方向
    if (diff > 0) {
      slideNext();
    } else {
      slidePrev();
    }

    lastTouchPos = currentTouchPos;
  });

  // 监听容器的滑动结束事件
  container.addEventListener('touchend', function (event) {
    reset();
    container.removeEventListener('touchmove', onTouchMove);
    container.removeEventListener('touchend', onTouchEnd);
  });
});
