Vue 实现定时无缝滚动轮播图 - 带按钮、圆点控制及鼠标悬停停止

<template>
  <div class='carousel' @mouseover='stopTimer' @mouseout='startTimer'>
    <div class='carousel-container' :style="{ transform: 'translateX(' + (-currentIndex * 100) + '%)' }">
      <div class='carousel-item' v-for='(item, index) in items' :key='index'>
        <img :src='item.imgSrc' alt=''>
      </div>
    </div>
    <div class='carousel-controls'>
      <button class='carousel-control' @click='prev'><i class='fas fa-chevron-left'></i></button>
      <button class='carousel-control' @click='next'><i class='fas fa-chevron-right'></i></button>
    </div>
    <div class='carousel-dots'>
      <span class='carousel-dot' v-for='(item, index) in items' :key='index' :class="{ 'active': index === currentIndex }" @click='goTo(index)'></span>

<p>该轮播图组件使用 Vue 实现，具备以下特点：</p>
<ul>
<li>使用 flex 布局实现图片水平排列</li>
<li>使用 transform 属性实现图片滚动效果</li>
<li>使用 setInterval 函数实现定时滚动</li>
<li>使用 clearInterval 函数实现滚动停止</li>
<li>使用 左右按钮 和 底部圆点 实现用户控制图片的滚动</li>
<li>鼠标悬停在轮播图上时，滚动会停止，鼠标移开后继续滚动</li>
</ul>
<p>通过以上实现，我们就可以得到一个基于 Vue 的定时无缝滚动的轮播图，并具备用户控制和交互的功能。</p>
