因爲自身的項目比較簡單,只有幾個H5頁面,用來嵌入app中,全部沒有引入移動端的UI框架,可是介於能讓用戶在瀏覽H5頁面時有下拉刷新和上拉加載,有更好的用戶體驗,本身寫組件實現。css
1、下拉刷新
DropDownRefresh.vue
html
<template lang="html"> <div class="refresh-moudle" @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="dropDownInfo.downImg" class="down-img" :src="require('../../assets/images/refreshAndReload/'+dropDownInfo.downImg)"> <span class="down-text">{{dropDownInfo.downText}}</span> </div> <div class="up-tip" v-if="dropDownState==2"> <img v-if="dropDownInfo.upImg" class="up-img" :src="require('../../assets/images/refreshAndReload/'+dropDownInfo.upImg)"> <span class="up-text">{{dropDownInfo.upText}}</span> </div> <div class="refresh-tip" v-if="dropDownState==3"> <img v-if="dropDownInfo.refreshImg" class="refresh-img" :src="require('../../assets/images/loading/'+dropDownInfo.refreshImg)"> <span class="refresh-text">{{dropDownInfo.refreshText}}</span> </div> </slot> </header> <slot></slot> </div> </template> <script> export default { props: { onRefresh: { type: Function, required: false } }, data () { return { defaultOffset: 50, // 默認高度, 相應的修改.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, // 顯示1:下拉能夠刷新, 2:鬆開當即刷新, 3:正在刷新數據中... dropDownInfo: { downText: '下拉能夠刷新', downImg: 'arrow.png', upText: '鬆開當即刷新', upImg: 'arrow.png', refreshText: '正在刷新數據...', refreshImg: 'loading.png' } } }, created () { if (document.querySelector('.down-tip')) { // 獲取不一樣手機的物理像素(dpr),以便適配rem this.defaultOffset = document.querySelector('.down-tip').clientHeight || this.defaultOffset } }, methods: { /** * 觸摸開始,手指點擊屏幕時 * @param {object} e Touch 對象包含的屬性 */ touchStart (e) { this.startY = e.targetTouches[0].pageY }, /** * 接觸點改變,滑動時 * @param {object} e Touch 對象包含的屬性 */ touchMove (e) { this.scrollIsToTop = document.documentElement.scrollTop || window.pageYOffset || document.body.scrollTop // safari 獲取scrollTop用window.pageYOffset if (e.targetTouches[0].pageY > this.startY) { // 下拉 this.isDropDown = true if (this.scrollIsToTop === 0 && !this.isRefreshing) { // 拉動的距離 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 // 去掉會致使ios沒法刷新 e.preventDefault() } } } else { this.isDropDown = false this.dropDownState = 1 } }, /** * 觸摸結束,手指離開屏幕時 * @param {object} e Touch 對象包含的屬性 */ 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 // 這是全是靜態數據,延時1200毫秒,給用戶一個刷新的感受,若是是接口數據的話,直接調接口便可 setTimeout(() => { this.onRefresh(this.refreshDone) }, 1200) }, /** * 刷新完成 */ refreshDone () { this.isRefreshing = false this.isDropDown = false this.dropDownState = 1 this.top = 0 } } } </script> <!-- Add "scoped" attribute to limit CSS to this component only --> <style scoped> .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% { transform: rotate(0deg); } 100% { transform: rotate(-180deg); } } .refresh-img { width: 35px; height: 35px; margin-right: 15px; animation: rotating 1.5s linear infinite; } @keyframes rotating { 0% { transform: rotate(0deg); } 100% { transform: rotate(1turn); } } </style>
2、上拉加載
PullUpReload.vue
vue
<template lang="html"> <div class="load-moudle" @touchstart="touchStart($event)" @touchmove="touchMove($event)" @touchend="touchend($event)"> <slot></slot> <footer class="load-more"> <slot name="load-more"> <div class="more-tip" v-if="pullUpState==1"> <span class="more-text">{{pullUpInfo.moreText}}</span> </div> <div class="loading-tip" v-if="pullUpState==2"> <span class="loading-icon"></span> <span class="loading-text">{{pullUpInfo.loadingText}}</span> </div> <div class="no-more-tip" v-if="pullUpState==3"> <span class="connecting-line"></span> <span class="no-more-text">{{pullUpInfo.noMoreText}}</span> <span class="connecting-line"></span> </div> </slot> </footer> </div> </template> <script> export default { props: { parentPullUpState: { default: 0 }, onInfiniteLoad: { type: Function, require: false } }, data () { return { top: 0, pullUpState: 0, // 1:上拉加載更多, 2:加載中……, 3:我是有底線的 isLoading: false, // 是否正在加載 pullUpInfo: { moreText: '上拉加載更多', loadingText: '數據加載中...', noMoreText: '我是有底線的' }, startX: 0, startY: 0, endX: 0, endY: 0 } }, methods: { /** * 觸摸開始,手指點擊屏幕時 * @param {object} e Touch 對象包含的屬性 */ touchStart (e) { this.startX = e.touches[0].pageX this.startY = e.touches[0].pageY }, /** * 接觸點改變,滑動時 * @param {object} e Touch 對象包含的屬性 */ 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('沒滑動') 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: } }, /** * 觸摸結束,手指離開屏幕時 * @param {object} e Touch 對象包含的屬性 */ touchend (e) { this.isLoading = false }, /** * 判斷滾動條是否到底 */ scrollToTheEnd () { let innerHeight = document.querySelector('.load-moudle').clientHeight // 變量scrollTop是滾動條滾動時,距離頂部的距離 let scrollTop = document.documentElement.scrollTop || window.pageYOffset || document.body.scrollTop // 變量scrollHeight是滾動條的總高度 let scrollHeight = document.documentElement.clientHeight || document.body.scrollHeight // 滾動條到底部的條件 if (scrollTop + scrollHeight >= innerHeight) { if (this.pullUpState !== 3 && !this.isLoading) { this.infiniteLoad() } // console.log('距頂部' + scrollTop + '滾動條總高度' + scrollHeight + '內容高度' + innerHeight) } }, /** * 上拉加載數據 */ infiniteLoad () { if (this.pullUpState !== 0) { this.pullUpState = 2 this.isLoading = true this.onInfiniteLoad(this.infiniteLoadDone) } }, /** * 加載數據完成 */ infiniteLoadDone () { this.pullUpState = 1 }, /** * 返回角度 */ getSlideAngle (dx, dy) { return Math.atan2(dy, dx) * 180 / Math.PI }, /** * 根據起點和終點返回方向 1:向上,2:向下,3:向左,4:向右,0:未滑動 * @param {number} startX X軸開始位置 * @param {number} startY X軸結束位置 * @param {number} endX Y軸開始位置 * @param {number} endY Y軸結束位置 */ getSlideDirection (startX, startY, endX, endY) { let dy = startY - endY let dx = endX - startX let result = 0 // 若是滑動距離過短 if (Math.abs(dx) < 2 && Math.abs(dy) < 2) { return result } let angle = this.getSlideAngle(dx, dy) if (angle >= -45 && angle < 45) { result = 4 } else if (angle >= 45 && angle < 135) { result = 1 } else if (angle >= -135 && angle < -45) { result = 2 } else if ((angle >= 135 && angle <= 180) || (angle >= -180 && angle < -135)) { result = 3 } return result } }, 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: #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 { 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); } } .connecting-line { display: inline-flex; width: 150px; height: 2px; background: #ddd; margin-left: 20px; margin-right: 20px; } </style>
3、對兩個組件的使用ios
<template> <section class="container"> <v-refresh :on-refresh="onRefresh"> <v-reload :on-infinite-load="onInfiniteLoad" :parent-pull-up-state="infiniteLoadData.pullUpState" > <div class="bank-box"> <div class="bank-list" v-for="item in bankList" :key="item.id"> <div class="bank-icon" :style="{ 'background': 'url(' + require('../../assets/images/bankIcon/'+item.iconName) + ') no-repeat', 'background-size': '100%' }" ></div> <span class="bank-name">{{item.bankName}}</span> </div> </div> <div class="hot-box"> <div class="hot-header"> <span class="hot-name">熱門推薦</span> <div class="more-box"> <span class="more-text">查看更多</span> <span class="more-icon"></span> </div> </div> <div class="hot-centenrt"> <div class="hot-left"> <span class="left-name">{{hotLeft.name}}</span> <span class="left-desc">{{hotLeft.desc}}</span> <div class="left-img" :style="{ 'background': 'url(' + require('../../assets/images/bank/'+hotLeft.imgName) + ') no-repeat', 'background-size': '100%' }" ></div> </div> <div class="hot-right"> <div class="right-top"> <div class="text-box"> <span class="right-name">{{centenrtOne.name}}</span> <span class="right-desc">{{centenrtOne.desc}}</span> </div> <div class="right-img" :style="{ 'background': 'url(' + require('../../assets/images/bank/'+centenrtOne.imgName) + ') no-repeat', 'background-size': '100%' }" ></div> </div> <div class="hot-right-bottom"> <div class="text-box2"> <span class="right-name2">{{centenrtTwo.name}}</span> <span class="right-desc2">{{centenrtTwo.desc}}</span> </div> <div class="right-img" :style="{ 'background': 'url(' + require('../../assets/images/bank/'+centenrtTwo.imgName) + ') no-repeat', 'background-size': '100%' }" ></div> </div> </div> </div> </div> <div class="card-state"> <div class="card-progress border-right"> <div class="progress-icon"></div> <div class="card-text"> <span class="card-name">辦卡進度</span> <span class="card-desc">讓等待隨處可見</span> </div> </div> <div class="card-activation"> <div class="activation-icon"></div> <div class="card-text"> <span class="card-name">辦卡激活</span> <span class="card-desc">讓等待隨處可見</span> </div> </div> </div> <div class="card-order"> <div class="border-bottom card-bottom"> <div class="hot-header"> <span class="hot-name">熱卡排行</span> </div> </div> <div slot="load-more"> <li class="card-list" v-for="(item,index) in infiniteLoadData.pullUpList" :key="item.id" > <div class="card-content" :class="infiniteLoadData.pullUpList.length - 1 != index?

這裏只是展現了一下效果,使用的全是靜態數據,若是要用接口數據的話,this.getPullUpMoreData()
方法直接換成接口數據的方法,並將判斷的邏輯移到接口方法裏,固然根據實際狀況,分頁呀啥的作作適當的修改。web
