    <div class="box">
        <transition name="roll">
            <div class="inner" :key="index">
                {{list[index]}}
            </div>
        </transition>
    </div>
</template>

<script setup>
import { reactive, ref } from 'vue'

const list = reactive(['轮播文字11111111', '轮播文字222222222222', '轮播文字33333333333333333333'])
const index = ref(0)
setInterval(() => (index.value === list.length - 1 ? (index.value = 0) : index.value++), 2000)
</script>
