el-carousel和el-image组合实现swiper左右滑动图片，点击某张图片放大预览的效果

<template>
    <el-carousel 
        class="image-swiper" 
        :height="'100%'" 
        :indicator-position="swiperItems.length <= 1 ? 'none' : ''"
        :arrow="swiperItems.length <= 1 ? 'never' : ''">
        <el-carousel-item v-for="(a, $i) in swiperItems" :key="$i">
            <el-image 
                style="width: 100%; height: 100%" 
                :src="a.sm" 
                :preview-src-list="swiperItems.map(v => v.lg)" 
                :initial-index="$i"
                :fit="'cover'">
            </el-image>
        </el-carousel-item>
    </el-carousel>
</template>
<script>
export default {
    data() {
        return {
            swiperItems: [
                {
                    sm: "static/img/sm/1.jpg",
                    lg: "static/img/lg/1.jpg",
                },
                {
                    sm: "static/img/sm/2.jpg",
                    lg: "static/img/lg/2.jpg",
                },
                {
                    sm: "static/img/sm/3.jpg",
                    lg: "static/img/lg/3.jpg",
                },
            ],
        };
    },
};
</script>
<style lang="scss" scoped>
.image-swiper {
    position: absolute;
    width: 400px;
    height: 300px;
    position: absolute;
    margin: auto;
    top: 0;
