組裝pos機插件,編程中的技術積累 betterscroll組件再次封裝

網上有很多關于組裝pos機插件,編程中的技術積累 betterscroll組件再次封裝的知識，也有很多人為大家解答關于組裝pos機插件的問題，今天pos機之家(www.tonybus.com)為大家整理了關于這方面的知識，讓我們一起來看下吧!

組裝pos機插件

也是公司項目 ，內部app的資訊模塊整改，改是不可能改的，之前還是用jquery。感覺越改越混亂，還是重做。就仿著今日頭條、等資訊頁面做了一個dome，話不多說，先看效果!

效果圖

效果看完，感覺還行的話，接著就往下看開啟爬坑之路！

先打一個無償廣告 上圖的gif 是通過LICEcap 軟件錄屏制作的！下載地址：官網地址，支持window mac ，無插件 無廣告 完全免費！確實好用，比起國內的動不動就要會員才能導出的***軟件要好的多

一、效果分析

看起來好像很常見，但是這個整體效果完成，對better scroll就比較熟悉了 做平常的滾動導航列表、輪播圖、下拉刷新、上拉加載等ui模板都應該小kiss了。頁面主要也就三個功能

頂部的可滑動導航列表中間的可滑動切換頁 和導航列表有聯動效果每頁列表頁都支持下拉刷新、上拉加載二、功能實現

1.插件安裝

基于vue 和better scroll的項目，用vue cli 安裝vue的環境搭建 這一塊就不多說

better scroll的安裝

npm install better-scroll@next -S

使用的話就比較簡單

import BScroll from 'better-scroll';mounted() {this.initBscroll()},methods: {initBscroll() {this.bscroll = new BScroll(this.$refs.bsWrapper, {scrollY: true,bounceTime: TIME_BOUNCE,pullDownrefresh: {threshold: THRESHOLD,stop: STOP}})this.bscroll.on('scroll', this.scrollHandler)},scrollHandler(pos) {console.log(pos.y)},}

使用的話也就是配置參數 對于這些參數詳細解釋就 分享一下api鏈接http://ustbhuangyi.github.io/better-scroll/doc/api.html

重要的標記一下：

一類是屬性 在new的時候傳入的 如scrollY:true 設置豎直方向可以滾動

一類是方法 就是在用戶操作過程中可以調用該方法 如scroll 就是頁面滾動中觸發的，調用語法如下

this.bscroll.on('scroll', this.scrollHandler)scrollHandler(pos) {console.log(pos.y)},//上面為實時打印滾動的位置案例eventPassthrough

在屬性上 這里要著重介紹 eventPassthrough屬性！該屬性默認值為'' 可以設置'vertical'、'horizontal'簡單解釋一下 當eventPassthrough 設置vertical 時 該實例 只會相應水平的滑動事件 豎直方向事件將不會影響它如咱們案例中的 左右切換和下拉刷新就必須設置該屬性 ，不讓相互影響 整個頁面滑動效果就很卡頓

scrollToElement(el, time, offsetX, offsetY, easing)

在放方法上也介紹一下scrollToElement，就是滾動到指定元素 ，五個參數（滾動到哪個對象 所需時間 x偏移 y偏移 動畫效果）x偏移和y偏移 設置為true是 就會滾動到該元素中心位置

2.頂部滾動導航實現

也提一下滾動原理 雖然黃佚老師講的很詳細了，但是還是提一下，這個主要就是為了頁面如何布局，內容區域大于wepper 才可以觸發滾動，因此必須控制wrpper的大小，不能讓它的大小讓子元素撐開

滾動原理

先是進行頁面布局吧

頂部滾動

頂部這一塊紅色標出的就是wrapper 大小固定 ，綠色的就是內容部分 可滾動；

而紅色區域的大小就是屏幕的寬度減去兩邊的寬度 這個實現可以用flex 實現 可以用aclc實現 個人還是傾向于flex

布局完成之后就是 進行better scroll的初始化 對于這個實現就是 需要在激活狀態下滾動至該元素的最中間直接用scrollToElement實現 整體代碼如下：

<template><div class="page" ><div class="topcontent"><div class="tranbox"></div><div class="tab" ref="linescoll"><div class="tabitems" ref="picList"><div v-for="(item,index) in navlist" class="tabitem" :class="item.id==activeitem.id?'tabactived':''" @click="changtab(item)" :key="index">{{item.title}}</div></div></div><div class="additem">+</div></div></div></template><script>import BScroll from 'better-scroll';export default {data() {return {navlist:[{title:'要聞', action:'', type:'', from:'ezx',id:1},{title:'7*24', action:'', type:'', from:'ezx',id:2},{title:'自選股', action:'', type:'', from:'ezx',id:3},{title:'公司研報', action:'', type:'', from:'zz',id:4},{title:'行業研究', action:'', type:'', from:'zz',id:5},{title:'新三板新聞', action:'', type:'', from:'zz',id:6},{title:'期貨研究', action:'', type:'', from:'zz',id:7},],activeitem: {},};},watch:{activeitem:function(val) {let idx;this.navlist.map((item,index)=>{if(item.id == val.id){idx = index}});this.changetitle(val,idx);}},mounted(){this.init();this.activeitem = {title:'7*24', action:'', type:'', from:'ezx',id:2};},methods: {init() {this.$nextTick(()=>{//設置頂部滾動 navlistthis.scrollmethod = new BScroll(this.$refs.linescoll, {bounce: true,eventPassthrough: 'vertical',scrollX: true,scrollY: false,preventDefault: false});});},changetitle(item,index){let idx = index+1;let dom = document.querySelector('.tabitems .tabitem:nth-child(' + idx + ')');this.$nextTick(() => {//標題滾動到對應位置// 五個參數 滾動到元素 時間 水平偏移 豎直偏移 后兩個為true 則是中心位置 最后一個 設置動畫效果this.scrollmethod.scrollToElement(dom, null, true, true);})},changtab(item) {this.activeitem = item;}}};</script><style lang="scss" scoped>.page{display: flex;flex-direction: column;width="360px",height="auto" />

line-height: 24px;padding:10px 17px;color: #333333;text-align: center;display: inline-flex;justify-content: center;box-sizing: border-box;flex-wrap: nowrap;white-space: nowrap;}.tabactived{color:#F14D44;position: relative;font-size: 17px;line-height: 24px;&:after{position: absolute;content: "";bottom: 0;left: 20%;width="360px",height="auto" />

復制代碼就可以實現以下效果 算是一個 簡單的滾動導航條了吧

頂部滾動效果

2. 滑動切換slider實現

用better scroll實現slider也是相當方便 直接就slider這個對象屬性，初始化時候添加進來就好，而這個頁面布局如下

內容橫向滑動原理

根據咱們的項目 添加一些初始數據 在init 中在初始化一下 slider

<template><div class="page" ><div class="topcontent"><div class="tranbox"></div><div class="tab" ref="linescoll"><div class="tabitems" ref="picList"><div v-for="(item,index) in navlist" class="tabitem" :class="item.id==activeitem.id?'tabactived':''" @click="changtab(item)" :key="index">{{item.title}}</div></div></div><div class="additem">+</div></div><div class="center"><div class="slide-banner-scroll" ref="slide"><div class="slide-banner-wrapper"><div class="slide-item" v-for="item in navlist" :key="item.id"><div class="zxlinelistbox" :class="'page'+item.id"><div class="zxcontentbox"><zxlist :zxlist="listdata" :readId="readId" @zxitemclick="zxitemclick"></zxlist></div></div></div></div></div></div></div></template><script>import BScroll from 'better-scroll';import zxlist from '../components/zxlist'export default {components:{zxlist:zxlist},data() {return {listdata:[],navlist:[{title:'要聞', action:'', type:'',

'vertical',scrollX: true,scrollY: false,preventDefault: false});//設置輪播頁面this.slide = new BScroll(this.$refs.slide, {scrollX: true,scrollY: false,slide: {loop: false,threshold: 100},eventPassthrough:"vertical",momentum: false,// bounce: true,})this.slide.on('scrollEnd', this._onScrollEnd)});},_onScrollEnd() {console.log('endssssss')let index = this.slide.getCurrentPage().pageX;let item = this.navlist[index];this.activeitem = item;},changetitle(item,index){let idx = index+1;let dom = document.querySelector('.tabitems .tabitem:nth-child(' + idx + ')');this.$nextTick(() => {//標題滾動到對應位置// 五個參數 滾動到元素 時間 水平偏移 豎直偏移 后兩個為true 則是中心位置 最后一個 設置動畫效果this.scrollmethod.scrollToElement(dom, null, true, true);this.scrollmethod.refresh();//詳情頁滾動到對應頁面this.slide.goToPage(index);})},changtab(item) {this.activeitem = item;}}};</script><style lang="scss" scoped>.page{display: flex;flex-direction: column;width="360px",height="auto" />

其中silder有個方法就是 goToPage

this.slide.goToPage(index);

傳入頁碼 自動滾動至對應頁數 所用的變化都在watch 中實現，這樣保證了數據變化就可以觸發 實現了上下聯動效果 效果如下

內容橫向滾動效果

4.實現下拉刷新 上拉加載更多

現在是水平方向有多個頁面 要實現下拉刷新 上拉加載，為了保證每個頁面的獨立性，在每個頁面激活后 給該頁面增加該效果，就在watch中添加，為了防止其他頁面干擾 切換前先清除下拉 scroll 為了防止和slider干擾 設置一下eventPassthrough:"horizontal" 保證水平方向不干擾別人 slider 也設置eventPassthrough:"vertical", 保證豎直方向不干擾別人。

實現下拉效果和加載更多效果在初始化的時候還需要設置pullUpLoad 和 pullDownRefresh

初始化如下

this.bscroll = new BScroll(scldom, {click: true,scrollX: false,scrollY: true,// momentum:false,bounceTime: 800,pullUpLoad:{threshold: 70,},pullDownRefresh: {threshold: 20,stop:56},eventPassthrough:"horizontal"});}this.bscroll.on('pullingDown', this.pullingDownHandler)this.bscroll.on('pullingUp', this.pullingUpHandler)//修復問題：在頁面來回切換過程中 發現下拉刷新 的定時器沒有清除 導致 下拉刷新沒有重置 因此在//初始化時加了一下判斷initscrldata(){this.loadingtxt='下拉刷新';this.dragTip={text:"釋放刷新",translate:-50,showLoding:false},this.beforePullDown=true;this.isPullingDown= false;this.isPullUpLoad=true;this.canloading=true;if(this.bscroll){this.bscroll.finishPullDown()this.bscroll.finishPullUp();this.bscroll.destroy();}if(this.timer2){let vm = this;clearTimeout(vm.timer2)}if(this.timer){let vm = this;clearTimeout(vm.timer)}if(this.timer1){let vm = this;clearTimeout(vm.timer1)}this.bscroll = null;},

最終代碼如下。復制即可使用！

用的sass 作為css的預編譯，作為demo 就沒分模塊化，也方便快速實現功能 和改造，本來想弄githup上 但是一想光pull 和npm 一下就很費時間 直接貼代碼好了 ，只要有sass 和 npm 一下better scroll 創建一個vue 復制進去就可以跑起來 感覺更方便一些！

手機pos機怎么弄

手機POS機分為帶刷卡頭的和不帶刷卡頭的，不帶卡頭的是直接在手機里面純乎輸入卡號和密碼就可以了，帶卡頭的需要直接用卡頭刷卡然后在手機上輸入密碼，辦理時需要身份證和銀行卡就行了，審核成功后再在手瞎御機上安裝一個軟件就可以磨褲巖使用了，實時到帳。如果在深圳的話可以聯系我。

以上就是關于組裝pos機插件,編程中的技術積累 betterscroll組件再次封裝的知識，后面我們會繼續為大家整理關于組裝pos機插件的知識，希望能夠幫助到大家！
