vue实现原生下拉刷新

本文实例为大家分享了vue实现原生下拉刷新的具体代码，供大家参考，具体内容如下
这是动画样式
文字样式
html代码
<template> <div class="car-box"> <div class="car">下拉刷新</div> <div class="box" @touchstart="fnstart" ref="Element"> <div class="con-txt">上拉刷新</div> </div> </div> </template>
js代码
<script>
export default {
methods: {
fnstart(ev) {
this.$refs["Element"].style.top = 0;
this.scroolTop =
ev.changedTouches[0].pageY - this.$refs["Element"].offsetTop;
document.ontouchmove = this.fnmove;
document.ontouchend = this.fnEnd;
ev.preventDefault && ev.preventDefault();
},
fnmove(ev) {
ev.target.parentNode.children[0].innerHTML = "下拉刷新";
this.T = ev.changedTouches[0].pageY - this.scroolTop;
if (this.scale > 0.12) {
this.scale = 1 - this.T / 200;
} else {
this.scale = 0.12;
}
this.$refs["Element"].style.top = this.T * this.scale + "px";
},
fnEnd(ev) {
ev.target.parentNode.children[0].innerHTML = "正在刷新...";
document.ontouchmove = null;
document.ontouchend = null;
setTimeout(() => {
this.$refs["Element"].style.top = 0;
this.$refs["Element"].style.transition = ".3s ease all";
this.$refs["Element"].addEventListener("transitionend", () => {
this.$refs["Element"].style.transition = null;
});
}, 3000);
},
},
};
</script>
css代码 我这边用的是scss
<style lang="scss" scoped>
.box {
text-align: center;
height: 600px;
width: 100vw;
background-color: orange;
position: absolute;
left: 0;
top: 0;
}
.car {
text-align: center;
margin: auto;
width: 199px;
height: 60px;
line-height: 60px;
background-position: 0 0;
background-size: 100% auto;
animation: animation_car 1.5s steps(1) infinite;
}
</style>
如果下拉刷新用动画就用这个css样式
图片的话我用的是28帧的 根据100除以28 也就是3.5 ，所以每3.5%换一个图，就能形成一个逐帧动画，每一个页面的宽高都不一样所以要计算 ，我的页面的大小是1080的这个也时我设置好的宽高。
这是代码
<style lang="scss" scoped>
.box {
text-align: center;
height: 600px;
width: 100vw;
background-color: orange;
position: absolute;
left: 0;
top: 0;
}
.car {
text-align: center;
margin: auto;
width: 199px;
height: 134px;
// margin-bottom: 200px;
background: url("../assets/img/car.png") no-repeat;
background-position: 0 0;
background-size: 100% auto;
animation: animation_car 1.5s steps(1) infinite;
}
@keyframes animation_car {
0% {
background-position: 0px;
}
3.5% {
background-position: 0px -134px;
