Vue 經常使用 transition 動畫效果記錄

先簡單介紹下 transition 標籤的使用方法

主要用於 v-show, v-if 或 router-view 的進出場動畫

• 模板

<transition name="name" >
      <div v-show="show" ></div>
      <div v-if="show" ></div>
      <router-view/>
    </transition>
複製代碼

• CSS

// 定義進入前與離開後狀態
    .name-enter, .name-leave-to {
      ...
    }
    // 定義離開前與進入後狀態
    .name-leave, .name-enter-to {
      ...
    }
    // 定義進出過程
    .name-enter-active, .name-leave-active {
      transition: all .5s
    }
