vue实现动画

动画效果

基本使用

方式1：

<template>
  <div>
      <button @click="isShow = !isShow">显示/隐藏</button>
      <!-- apper默认开始就显示动画 -->
      <transition name="hello" appear>
          <h1 v-show="isShow">你好呀！</h1>
      </transition>
  </div>
</template>

<script>
export default {
    name:'Test',
    data() {
        return {
            isShow:true,
        }
    },
}
</script>

<style scoped>
    h1{
        background-color: aqua;
    }

    .hello-enter-active{
        animation: move 1s;
    }

    .hello-leave-active{
        animation: move 1s reverse;
    }

    @keyframes move{
        from{
            transform: translateX(-100%);
        }
        to{
            transform: translateX(0px);
        }
    }
</style>

方式2：

<template>
  <div>
      <button @click="isShow = !isShow">显示/隐藏</button>
      
      <transition-group name="hello" appear>
          <h1 v-show="!isShow" key="1">你好呀！</h1>
          <h1 v-show="isShow" key="2">你好2呀！</h1>
      </transition-group>
  </div>
</template>

<script>
export default {
    name:'Test2',
    data() {
        return {
            isShow:true,
        }
    },
}
</script>

<style scoped>
    h1{
        background-color: aqua;
        
    }
    /* 进入的起点与离开的终点 */
    .hello-enter,.hello-leave-to{
        transform: translateX(-100%);
    }
    .hello-enter-active,.hello-leave-active{
        transition: 0.5s linear;
    }
    /* 进入的终点离开的起点 */
    .hello-enter-to,.hello-leave{
        transform: translateX(0);
    }
    
    
</style>

第三方动画库

• Animate.css

  1. 安装css库：npm install animate.css

  2. 直接引入样式：import ‘animate.css’

  3. 配置属性：

     <transition-group 
         appear
         name="animate__animated animate__bounce" 
         enter-active-class="animate__swing"
         leave-active-class="animate__backOutLeft"
     >
