vue移动端下拉刷新和上拉加载的实现代码
简介由于自身的项目比较简单，只有几个H5页面，用来嵌入app中，所有没有引入移动端的UI框架，但是介于能让用户在浏览H5页面时有下拉刷新和上拉加载，有更好的用户体验，自己写组件实现。1、下拉刷新DropDownRefresh.vue
由于自身的项目比较简单，只有几个H5页面，用来嵌入app中，所有没有引入移动端的UI框架，但是介于能让用户在浏览H5页面时有下拉刷新和上拉加载，有更好的用户体验，自己写组件实现。
1、下拉刷新
DropDownRefresh.vue
<template lang="html">
<div class="refreshMoudle" @touchstart="touchStart($event)" @touchmove="touchMove($event)" @touchend="touchEnd($event)" :style="{transform: 'translate3d(0,' + top + 'px, 0)'}">
<header class="pull-refresh">
<slot name="pull-refresh">
<div class="down-tip" v-if="dropDownState==1">
<img v-if="dropDownStateText.downImg" class="down-tip-img" :src="/UploadFiles/2021-04-02/'+dropDownStateText.downImg)">
2、上拉加载PullUpReload.vue
<template lang="html">
<div class="loadMoudle" @touchstart="touchStart($event)" @touchmove="touchMove($event)" :style="{transform: 'translate3d(0,' + top + 'px, 0)'}">
<slot></slot>
<footer class="load-more">
<slot name="load-more">
<div class="moreData-tip" v-if="pullUpState==1">
<span class="moreData-tip-text">{{pullUpStateText.moreDataTxt}}</span>
</div>
<div class="loadingMoreData-tip" v-if="pullUpState==2">
<span class="icon-loading"></span>
<span class="loadingMoreData-tip-text">{{pullUpStateText.loadingMoreDataTxt}}</span>
</div>
<div class="noMoreData-tip" v-if="pullUpState==3">
<span class="connectingLine"></span>
<span class="noMoreData-tip-text">{{pullUpStateText.noMoreDataTxt}}</span>
<span class="connectingLine"></span>
</div>
</slot>
</footer>
</div>
</template>
<script>
export default {
props: {
parentPullUpState: {
default: 0
},
onInfiniteLoad: {
type: Function,
require: false
}
},
data () {
return {
top: 0,
startY: 0,
pullUpState: 0, // 1:上拉加载更多, 2:加载中……, 3:我是有底线的
isLoading: false, // 是否正在加载
pullUpStateText: {
moreDataTxt: '上拉加载更多',
loadingMoreDataTxt: '加载中...',
noMoreDataTxt: '我是有底线的'
}
}
},
methods: {
touchStart (e) {
this.startY = e.targetTouches[0].pageY
},
touchMove (e) {
if (e.targetTouches[0].pageY < this.startY) { // 上拉
this.judgeScrollBarToTheEnd()
}
},
// 判断滚动条是否到底
judgeScrollBarToTheEnd () {
let innerHeight = document.querySelector('.loadMoudle').clientHeight
// 变量scrollTop是滚动条滚动时，距离顶部的距离
let scrollTop = document.documentElement.scrollTop || window.pageYOffset || document.body.scrollTop
// 变量scrollHeight是滚动条的总高度
let scrollHeight = document.documentElement.clientHeight || document.body.scrollHeight
// 滚动条到底部的条件
if (scrollTop + scrollHeight >= innerHeight) {
if (this.pullUpState !== 3 && !this.isLoading) {
this.pullUpState = 1
this.infiniteLoad()
// setTimeout(() => {
// this.infiniteLoad()
// }, 200)
}
}
},
infiniteLoad () {
this.pullUpState = 2
this.isLoading = true
setTimeout(() => {
this.onInfiniteLoad(this.infiniteLoadDone)
}, 800)
},
infiniteLoadDone () {
this.pullUpState = 0
this.isLoading = false
}
},
watch: {
parentPullUpState (curVal, oldVal) {
this.pullUpState = curVal
}
}
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.load-more {
width: 100%;
color: #c0c0c0;
background: #f7f7f7;
}
.moreData-tip,
.loadingMoreData-tip,
.noMoreData-tip {
display: flex;
align-items: center;
justify-content: center;
height: 150px;
}
.loadMoudle .icon-loading {
display: inline-flex;
width: 35px;
height: 35px;
background: url(../../assets/images/refreshAndReload/loading.png) no-repeat;
background-size: cover;
margin-right: 5px;
animation: rotating 2s linear infinite;
}
@keyframes rotating {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(1turn);
}
}
.connectingLine {
display: inline-flex;
width: 150px;
height: 2px;
background: #ddd;
margin-left: 20px;
margin-right: 20px;
}
</style>
3、对两个组件的使用
