vue移动端实现红包雨效果

本文实例为大家分享了vue实现红包雨效果的具体代码，供大家参考，具体内容如下

下面是代码：

<template> <div class=ser_home> <ul class=red_packet id=red_packet> <template v-for=(item, index) in liParams> <li :style={ left: item.left, animationDuration: item.durTime, webkitAnimationDuration: item.durTime} :class=item.cls :data-index=index @webkitAnimationEnd=removeDom> <a href=javascript:;> <i :style={ transform: item.transforms, webkitTransform: item.transforms}></i> </a> </li> </template> </ul> </div> </template> <script> export default { data () { return { liParams: [], timer: null, duration: 10000 // 定义时间 } }, mounted () { this.startRedPacket() }, methods: { /** * 开启动画 */ startRedPacket() { let win = document.documentElement.clientWidth document.body.clientWidth let left = parseInt(Math.random() * (win - 50) + 0); let rotate = (parseInt(Math.random() * (45 - (-45)) - 45)) + deg; // 旋转角度 let scales = (Math.random() * (12 - 8 + 1) + 8) * 0.1; // 图片尺寸 let durTime = (Math.random() * (2.5 - 1.2 + 1) + 1.2) + s; // 时间 1.2和1.2这个数值保持一样 console.log(durTime) this.liParams.push({left: left+px, cls: move_1, transforms: rotate(+ rotate +) scale(+ scales +), durTime: durTime}) setTimeout( () => { // 多少时间结束 clearTimeout(this.timer) return; }, this.duration) this.timer = setTimeout( () => { this.startRedPacket() },100) }, /** * 回收dom节点 */ removeDom (e) { let target = e.currentTarget; document.querySelector(#red_packet).removeChild(target) } } } </script> <!-- Add scoped attribute to limit CSS to this component only --> <style scoped lang=scss> .ser_home { width: 100%; height: 100%; } .red_packet { display: block; position: relative; overflow: hidden; width: 100%; height: 100%; i { width: 48px; height: 69px; display: block; background: url(/hongbao.png) no-repeat; } li { position: absolute; animation: all 3s linear; top:-100px; z-index: 10; &.move_1 { -webkit-animation: aim_move 5s linear 1 forwards; animation: aim_move 5s linear 1 forwards; } } a { display: block; } } @keyframes aim_move { 0% { -webkit-transform: translateY(0); transform: translateY(0); } 100% { -webkit-transform: translateY(120vh); transform: translateY(120vh); } } </style>
