Vue 过渡与动画

Vue封装的过渡与动画: 在插入、更新或移除DOM元素时,在合适的时候给元素添加样式类名。

在这里插入图片描述
写法:

  1. 准备好样式:
    • 元素进入的样式:
      1. v-enter:进入的起点
      2. v-enter-active:进入过程中
      3. v-enter-to:进入的终点
    • 元素离开的样式:
      1. v-leave:离开的起点
      2. v-leave-active:离开过程中
      3. v-leave-to:离开的终点
  2. 使用====包裹要过度的元素,并配置name属性,此时需要将上面样式名为 v 换为 name
  3. 要让页面一开始就显示动画,需要添加appear
<transition name="hello" appear>
  <h1 v-show="isShow">你好啊!</h1>
</transition>

<style>
  .hello-enter-active{
    
    
    animation: hello 0.5s linear;
  }

  .hello-leave-active{
    
    
    animation: hello 0.5s linear reverse;
  }

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

4.备注: 若有多个元素需要过渡,则需要使用 ,且每个元素都要指定 key值

<transition-group name="hello" appear>
  <h1 v-show="!isShow" key="1">你好啊!</h1>
  <h1 v-show="isShow" key="2">尚硅谷!</h1>
</transition-group>

5.第三方动画库 Animate.css 网站:https://www.npmjs.com/package/animate.css

安装完成后,直接引用样式 import ‘animate.css’

<transition-group appear
          name="animate__animated animate__bounce"
          enter-active-class="animate__swing"
          leave-active-class="animate__backOutUp">
  <h1 v-show="!isShow" key="1">你好啊!</h1>
  <h1 v-show="isShow" key="2">尚硅谷!</h1>
</transition-group>

src/App.vue

<template>
	<div>
		<Test/>
		<Test2/>
		<Test3/>
	</div>
</template>

<script>
	import Test from './components/Test'
	import Test2 from './components/Test2'
	import Test3 from './components/Test3'

	export default {
    
    
		name:'App',
		components:{
    
    Test,Test2,Test3},
	}
</script>

src/components/test.vue

<template>
  <div>
    <button @click="isShow = !isShow">显示/隐藏</button>
    <transition name="hello" appear>
      <h1 v-show="isShow">你好啊!</h1>
    </transition>
  </div>
</template>

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

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

  .hello-enter-active{
    
    
    animation: atguigu 0.5s linear;
  }

  .hello-leave-active{
    
    
    animation: atguigu 0.5s linear reverse;
  }

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

  }
</script>

<style scoped>
  h1 {
    
    
    background-color: orange;
    /* transition: 0.5s linear; */
  }
  /* 进入的起点、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);
  }
