內(nèi)容切換控制效果

注意：

key：可以為任意值，通過key值切換而控制動畫切換。組件可以任意，不變都行，變不變?nèi)Q于自己?？梢杂胏omponent標簽配合is，或者直接v-if也可以。
綁定key的那個組件需要設置為絕對定位，否則切換會出現(xiàn)卡頓。也可以設置mode="out-in"或者mode=“in-out” 一前一后。看自己個人的需求了

<template>
  <div>
    <transition name="fade">
      <button class="position" @click="change" :key="status">
        組件
      </button>
    </transition>
  </div>
</template>

<script>
export default {
  data () {
    return {
      status: '1',
    }
  },
  methods: {
    change () {
      if(this.docState === '1'){
        this.docState = '2'
      }else{
        this.docState = '1'
      }
    }
  }
}
</script>

<style scoped lang="less">
.fade-enter-active,
.fade-leave-active {
  transition: all .5s;
}
 .fade-leave-to  {
  opacity: 0;
  transform: translateX(20px);
}
.fade-enter{
  opacity: 0;
  transform: translateX(-20px);
}
.position{
  position: absolute;
}
</style>

配合animate框架使用

注意

name的值必須設置為：custom-classes-transition
enter-active-class， leave-active-class來控制出現(xiàn)和消失的樣式

<link  rel="external nofollow"  rel="stylesheet" type="text/css">

<div id="example-3">
  <button @click="show = !show">
    Toggle render
  </button>
  <transition
    name="custom-classes-transition"
    enter-active-class="animated tada"
    leave-active-class="animated bounceOutRight"
  >
    <p v-if="show">hello</p>
  </transition>
</div>
