el-image实现点击哪张图片就预览哪张（element-plus）

<div v-for="(item,index) in url_list" :key="index" style="margin-right: 10px;">
      <el-image
         style="width: 100px; height: 100px"
         :src="item"
         fit="fill"
         :preview-src-list="getPrivewImages(index)">
      </el-image>
</div>

其中url_list就是你要展示的图片列表

const url_list = [
    'https://fuss10.elemecdn.com/a/3f/3302e58f9a181d2509f3dc0fa68b0jpeg.jpeg',
    'https://fuss10.elemecdn.com/1/34/19aa98b1fcb2781c4fba33d850549jpeg.jpeg',
    'https://fuss10.elemecdn.com/0/6f/e35ff375812e6b0020b6b4e8f9583jpeg.jpeg',
    'https://fuss10.elemecdn.com/9/bb/e27858e973f5d7d3904835f46abbdjpeg.jpeg',
    'https://fuss10.elemecdn.com/d/e6/c4d93a3805b3ce3f323f7974e6f78jpeg.jpeg',
    'https://fuss10.elemecdn.com/3/28/bbf893f792f03a54408b3b7a7ebf0jpeg.jpeg',
    'https://fuss10.elemecdn.com/2/11/6535bcfb26e4c79b48ddde44f4b6fjpeg.jpeg'
]

然后就是实现预览功能

function getPrivewImages (index) {
    let tempImgList = [...url_list];//所有图片地址
    if (index == 0) return tempImgList;
    // 调整图片顺序，把当前图片放在第一位
    let start = tempImgList.splice(index);
    let remain = tempImgList.splice(0, index);
    return start.concat(remain);//将当前图片调整成点击缩略图的那张图片
}
