前言
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
{{dropDownInfo.downText}}
{{dropDownInfo.upText}}
{{dropDownInfo.refreshText}}
export default {
props: {
onRefresh: {
type: Function,
required: false
}
},
data () {
return {
defaultOffset: 50, // 默认高度, 相应的修改.releshMoudle的margin-top和.down-tip, .up-tip, .refresh-tip的height
top: 0,
scrollIsToTop: 0,
startY: 0,
isDropDown: false, // 是否下拉
isRefreshing: false, // 是否正在刷新
dropDownState: 1, // 显示1:下拉可以刷新, 2:松开立即刷新, 3:正在刷新数据中...
dropDownInfo: {
downText: '下拉可以刷新',
downImg: 'arrow.png',
upText: '松开立即刷新',
upImg: 'arrow.png',
refreshText: '正在刷新数据...',
refreshImg: 'loading.png'
}
}
},
created () {
if (document.querySelector('.down-tip')) {
// 获取不同手机的物理像素（dpr）,以便适配rem
this.defaultOffset = document.querySelector('.down-tip').clientHeight || this.defaultOffset
}
},
methods: {
/**
* 触摸开始，手指点击屏幕时
* @param {object} e Touch 对象包含的属性
*/
touchStart (e) {
this.startY = e.targetTouches[0].pageY
},
/**
* 接触点改变，滑动时
* @param {object} e Touch 对象包含的属性
*/
touchMove (e) {
this.scrollIsToTop = document.documentElement.scrollTop || window.pageYOffset || document.body.scrollTop // safari 获取scrollTop用window.pageYOffset
if (e.targetTouches[0].pageY > this.startY) {
// 下拉
this.isDropDown = true
if (this.scrollIsToTop === 0 && !this.isRefreshing) {
// 拉动的距离
let diff = e.targetTouches[0].pageY - this.startY - this.scrollIsToTop
this.top = Math.pow(diff, 0.8) + (this.dropDownState === 3 ? this.defaultOffset : 0)
if (this.top >= this.defaultOffset) {
this.dropDownState = 2
e.preventDefault()
} else {
this.dropDownState = 1
// 去掉会导致ios无法刷新
e.preventDefault()
}
}
} else {
this.isDropDown = false
this.dropDownState = 1
}
},
/**
* 触摸结束，手指离开屏幕时
* @param {object} e Touch 对象包含的属性
*/
touchEnd (e) {
if (this.isDropDown && !this.isRefreshing) {
if (this.top >= this.defaultOffset) {
// do refresh
this.refresh()
this.isRefreshing = true
} else {
// cancel refresh
this.isRefreshing = false
this.isDropDown = false
this.dropDownState = 1
this.top = 0
}
}
},
/**
* 刷新
*/
refresh () {
this.dropDownState = 3
this.top = this.defaultOffset
// 这是全是静态数据,延时1200毫秒，给用户一个刷新的感觉，如果是接口数据的话，直接调接口即可
setTimeout(() => {
this.onRefresh(this.refreshDone)
}, 1200)
},
/**
* 刷新完成
*/
refreshDone () {
this.isRefreshing = false
this.isDropDown = false
this.dropDownState = 1
this.top = 0
}
}
}
.refresh-moudle {
width: 100%;
margin-top: -100px;
-webkit-overflow-scrolling: touch; /* ios5+ */
}
.pull-refresh {
width: 100%;
color: #999;
transition-duration: 200ms;
font-size: 24px;
}
.refresh-moudle .down-tip,
.up-tip,
.refresh-tip {
display: flex;
align-items: center;
justify-content: center;
height: 100px;
}
.down-img {
width: 35px;
height: 35px;
margin-right: 15px;
transform: rotate(0deg);
animation: anticlockwise 0.8s ease;
}
@keyframes anticlockwise {
0% {
transform: rotate(-180deg);
}
100% {
transform: rotate(0deg);
}
}
.up-img {
width: 35px;
height: 35px;
margin-right: 15px;
transform: rotate(180deg);
animation: clockwise 0.8s ease;
}
@keyframes clockwise {
0% {

}
@keyframes rotating {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(1turn);
}
}
2、上拉加载 PullUpReload.vue
{{pullUpInfo.moreText}}
{{pullUpInfo.loadingText}}
{{pullUpInfo.noMoreText}}
export default {
props: {
parentPullUpState: {
default: 0
},
onInfiniteLoad: {
type: Function,
require: false
}
},
data () {
return {
top: 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
pullUpInfo: {
moreText: '上拉加载更多',
loadingText: '数据加载中...',
noMoreText: '我是有底线的'
},
startX: 0,
startY: 0,
endX: 0,
endY: 0
}
},
methods: {
/**
* 触摸开始，手指点击屏幕时
* @param {object} e Touch 对象包含的属性
*/
touchStart (e) {
this.startX = e.touches[0].pageX
this.startY = e.touches[0].pageY
},
/**
* 接触点改变，滑动时
* @param {object} e Touch 对象包含的属性
*/
touchMove (e) {
this.endX = e.changedTouches[0].pageX
this.endY = e.changedTouches[0].pageY
let direction = this.getSlideDirection(this.startX, this.startY, this.endX, this.endY)
switch (direction) {
case 0:
// console.log('没滑动')
break
case 1:
// console.log('向上')
this.scrollToTheEnd()
break
case 2:
// console.log('向下')
break
case 3:
// console.log('向左')
break
case 4:
// console.log('向右')
break
default:
}
},
/**
* 触摸结束，手指离开屏幕时
* @param {object} e Touch 对象包含的属性
*/
touchend (e) {
this.isLoading = false
},
/**
* 判断滚动条是否到底
*/
scrollToTheEnd () {
let innerHeight = document.querySelector('.load-moudle').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.infiniteLoad()
}
// console.log('距顶部' + scrollTop + '滚动条总高度' + scrollHeight + '内容高度' + innerHeight)
}
},
/**
* 上拉加载数据
*/
infiniteLoad () {
if (this.pullUpState !== 0) {
this.pullUpState = 2
this.isLoading = true
this.onInfiniteLoad(this.infiniteLoadDone)
}
},
/**
* 加载数据完成
*/
infiniteLoadDone () {
this.pullUpState = 1
},
/**
* 返回角度
*/
getSlideAngle (dx, dy) {
return Math.atan2(dy, dx) * 180 / Math.PI
},
/**
* 根据起点和终点返回方向 1：向上，2：向下，3：向左，4：向右,0：未滑动
* @param {number} startX X轴开始位置
* @param {number} startY X轴结束位置
* @param {number} endX Y轴开始位置
* @param {number} endY Y轴结束位置
*/
getSlideDirection (startX, startY, endX, endY) {
let dy = startY - endY
let dx = endX - startX
let result = 0
// 如果滑动距离太短
if (Math.abs(dx)
result = 4
} else if (angle >= 45 && angle
result = 2
} else if ((angle >= 135 && angle = -180 && angle
parentPullUpState (curVal, oldVal) {
this.pullUpState = curVal
}
}
}
.load-more {
width: 100%;
color: #c0c0c0;
background: #fafafa;
font-size: 24px;
}
.more-tip,
.loading-tip,
.no-more-tip {
display: flex;
align-items: center;
justify-content: center;
height: 150px;
}
.load-moudle .loading-icon {

background-size: cover;
margin-right: 5px;
animation: rotating 2s linear infinite;
}
@keyframes rotating {
0% {
transform: rotate(0deg);
}
100% {

}
}
.connecting-line {

这里只是展示了一下效果，使用的全是静态数据，如果要用接口数据的话，this.getPullUpMoreData() 方法直接换成接口数据的方法，并将判断的逻辑移到接口方法里，当然根据实际情况，分页呀啥的做做适当的修改。
