vue 在移动端实现红包雨 (兼容性好)
下面是代码:
<template>
<div class="ser_home">
<ul class="red_packet" ></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;

}
}
</style>
