vue实现滑梯下滑
Vue实现滑动下滑效果
滑动下滑效果通常用于页面滚动或元素动画场景,以下是几种实现方式:
使用CSS过渡动画
通过Vue绑定class或style实现CSS过渡效果:
<template>
<div
class="slide-down"
:class="{ 'active': isActive }"
@click="toggle"
>点击下滑</div>
</template>
<script>
export default {
data() {
return { isActive: false }
},
methods: {
toggle() { this.isActive = !this.isActive }
}
}
</script>
<style>
.slide-down {
height: 50px;
overflow: hidden;
transition: all 0.5s ease;
}
.slide-down.active {
height: 200px;
}
</style>
结合Vue Transition组件

实现更复杂的进入/离开动画:
<template>
<button @click="show = !show">切换</button>
<Transition name="slide">
<div v-if="show" class="content">滑动内容</div>
</Transition>
</template>
<style>
.slide-enter-active, .slide-leave-active {
transition: all 0.5s ease;
}
.slide-enter-from, .slide-leave-to {
transform: translateY(-100%);
opacity: 0;
}
</style>
使用第三方动画库
如Animate.css或GSAP:

<template>
<div
class="animated"
:class="{ 'slideInDown': animate }"
@mouseenter="animate = true"
>悬停触发动画</div>
</template>
<script>
import 'animate.css'
export default {
data() { return { animate: false } }
}
</script>
实现页面滚动效果
监听滚动事件实现视差效果:
mounted() {
window.addEventListener('scroll', this.handleScroll)
},
methods: {
handleScroll() {
const scrollY = window.scrollY
this.$refs.element.style.transform = `translateY(${scrollY * 0.5}px)`
}
}
注意事项
- 移动端需考虑touch事件兼容性
- 复杂动画建议使用requestAnimationFrame
- 离开页面时移除事件监听
- 性能优化可考虑will-change属性
