先看效果

編寫組件代碼 CarouselChart.vue

<template><div class='img-box'><el-button @click='previousImages' v-if='props.showBtn'>←</el-button><div class='img'><div style='display: flex;gap: 20px' id='move'><imgclass='img-item' v-for='(item) in props.imgList':key='item.src':src='item.src'alt='' /></div></div><el-button @click='nextImages' v-if='props.showBtn'>→</el-button><div class='spots' v-if='props.showSpot'><divclass='spot'v-for='(item,index) in props.imgList.length / 2':key='index':class="{'active':index*2 === currentIndex}"@click='setCurIndex(index)'></div></div></div>
