swiper-item内嵌套 scroll-view @change没有被触发 你们遇到过吗？怎么解决？

<!-- 显示区域 -->  
<swiper class="swiper-box-list" duration="300" @change="swiperChange" :current="currentIndex" style="height: 2500rpx;">  
    <block :slot="item.slot" v-for="(item,index) in 10" :key="index" :data-id="index">  
        <swiper-item>  
            <scroll-view class="swiper-topic-list" scroll-y="true" @scrolltolower="loadMore(index1)">  
                <view class="tabContent">  

                </view>  
            </scroll-view>  
        </swiper-item>  
    </block>  
</swiper>
