Transition与动画

1. Transition 组件

<template>
  <Transition name="fade">
    <div v-if="show">内容</div>
  </Transition>
</template>

<style>
.fade-enter-active,
.fade-leave-active {
  transition: opacity 0.3s ease;
}
.fade-enter-from,
.fade-leave-to {
  opacity: 0;
}
</style>

2. 过渡类名

3. JavaScript 钩子

<Transition
  @before-enter="onBeforeEnter"
  @enter="onEnter"
  @after-enter="onAfterEnter"
  @before-leave="onBeforeLeave"
  @leave="onLeave"
  @after-leave="onAfterLeave"
>
  <div v-if="show">内容</div>
</Transition>

4. TransitionGroup

<TransitionGroup name="list" tag="ul">
  <li v-for="item in items" :key="item.id">{{ item.text }}</li>
</TransitionGroup>

<style>
.list-move,
.list-enter-active,
.list-leave-active {
  transition: all 0.5s ease;
}
.list-enter-from,
.list-leave-to {
  opacity: 0;
  transform: translateX(30px);
}
.list-leave-active {
  position: absolute;
}
</style>

5. 自定义过渡

<Transition
  :duration="{ enter: 500, leave: 300 }"
  enter-active-class="animate__animated animate__fadeIn"
  leave-active-class="animate__animated animate__fadeOut"
>
  <div v-if="show">内容</div>
</Transition>
