vue中如何让el-carousel-item字符串滚动

你可以使用vue-awesome-swiper插件，并设置滚动效果。具体实现可以参考以下代码片段：

<template>
  <div id="app">
    <swiper :options="swiperOption">
      <swiper-slide>
        <el-carousel :interval="4000">
          <el-carousel-item v-for="(item, index) in list" :key="index">
            <div class="item-content">{{ item }}</div>
          </el-carousel-item>
        </el-carousel>
      </swiper-slide>
    </swiper>
  </div>
</template>

<script>
import 'swiper/css/swiper.css';
import { swiper, swiperSlide } from 'vue-awesome-swiper'

export default {
  name: 'app',
  components: {
    swiper,
    swiperSlide
  },
  data () {
    return {
      swiperOption: {
        autoplay: true,
        loop: true,
        pagination: {
          el: '.swiper-pagination'
        }
      },
      list: ['滚动1', '滚动2', '滚动3']
    }
  }
}
</script>

<style scoped>
  .item-content {
    width: 100%;
    height: 20px;
    overflow: hidden;
    white-space: nowrap;
    text-overflow: ellipsis;
  }
</style>
