<div class="swiper-slide" data-hash="slide3">
    <p class="ani" swiper-animate-effect="fadeInUp" swiper-animate-duration="1s" swiper-animate-delay="0.3s">fadeInUp</p>
    <p class="ani" swiper-animate-effect="bounce" swiper-animate-duration="1s" swiper-animate-delay="1.3s">bounce</p>
    <p class="ani" swiper-animate-effect="bounceOutRight" swiper-animate-duration="1s" swiper-animate-delay="16.3s">bounceOutRight</p>
</div>
比如想要在当前slide滑进来之后给这三个p标签添加进入的animate效果，然后想在点击下一页或是鼠标滚动slide切换之前给这三个p标签添加移出的animate效果需要如何实现
