組裝pos機(jī)插件,編程中的技術(shù)積累 betterscroll組件再次封裝

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

組裝pos機(jī)插件

也是公司項(xiàng)目，內(nèi)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(gè)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(gè)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(wǎng)地址，支持window mac ，無插件無廣告完全免費(fèi)！確實(shí)好用，比起國內(nèi)的動(dòng)不動(dòng)就要會(huì)員才能導(dǎo)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(gè)整體效果完成，對(duì)better scroll就比較熟悉了做平常的滾動(dòng)導(dǎo)航列表、輪播圖、下拉刷新、上拉加載等ui模板都應(yīng)該小kiss了。頁面主要也就三個(gè)功能

頂部的可滑動(dòng)導(dǎo)航列表中間的可滑動(dòng)切換頁和導(dǎo)航列表有聯(lián)動(dòng)效果每頁列表頁都支持下拉刷新、上拉加載二、功能實(shí)現(xiàn)

1.插件安裝

基于vue 和better scroll的項(xiàng)目，用vue cli 安裝vue的環(huán)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(shù) 對(duì)于這些參數(shù)詳細(xì)解釋就分享一下api鏈接http://ustbhuangyi.github.io/better-scroll/doc/api.html

重要的標(biāo)記一下：

一類是屬性在new的時(shí)候傳入的如scrollY:true 設(shè)置豎直方向可以滾動(dòng)

一類是方法就是在用戶操作過程中可以調(diào)用該方法如scroll 就是頁面滾動(dòng)中觸發(fā)的，調(diào)用語法如下

this.bscroll.on('scroll', this.scrollHandler)scrollHandler(pos) {console.log(pos.y)},//上面為實(shí)時(shí)打印滾動(dòng)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(rèn)值為'' 可以設(shè)置'vertical'、'horizontal'簡單解釋一下當(dāng)eventPassthrough 設(shè)置vertical 時(shí) 該實(shí)例只會(huì)相應(yīng)水平的滑動(dòng)事件豎直方向事件將不會(huì)影響它如咱們案例中的左右切換和下拉刷新就必須設(shè)置該屬性，不讓相互影響整個(gè)頁面滑動(dòng)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(dòng)到指定元素，五個(gè)參數(shù)（滾動(dòng)到哪個(gè)對(duì)象所需時(shí)間 x偏移 y偏移動(dòng)畫效果）x偏移和y偏移設(shè)置為true是就會(huì)滾動(dòng)到該元素中心位置

2.頂部滾動(dòng)導(dǎo)航實(shí)現(xiàn)

也提一下滾動(dòng)原理雖然黃佚老師講的很詳細(xì)了，但是還是提一下，這個(gè)主要就是為了頁面如何布局，內(nèi)容區(qū)域大于wepper 才可以觸發(fā)滾動(dòng)，因此必須控制wrpper的大小，不能讓它的大小讓子元素?fù)伍_

滾動(dòng)原理

先是進(jìn)行頁面布局吧

頂部滾動(dòng)

頂部這一塊紅色標(biāo)出的就是wrapper 大小固定，綠色的就是內(nèi)容部分可滾動(dòng)；

而紅色區(qū)域的大小就是屏幕的寬度減去兩邊的寬度這個(gè)實(shí)現(xiàn)可以用flex 實(shí)現(xiàn) 可以用aclc實(shí)現(xiàn) 個(gè)人還是傾向于flex

布局完成之后就是進(jìn)行better scroll的初始化對(duì)于這個(gè)實(shí)現(xiàn)就是需要在激活狀態(tài)下滾動(dòng)至該元素的最中間直接用scrollToElement實(shí)現(xiàn) 整體代碼如下：

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(fù)制代碼就可以實(shí)現(xiàn)以下效果算是一個(gè) 簡單的滾動(dòng)導(dǎo)航條了吧

頂部滾動(dòng)效果

2. 滑動(dòng)切換slider實(shí)現(xiàn)

用better scroll實(shí)現(xiàn)slider也是相當(dāng)方便直接就slider這個(gè)對(duì)象屬性，初始化時(shí)候添加進(jìn)來就好，而這個(gè)頁面布局如下

內(nèi)容橫向滑動(dòng)原理

根據(jù)咱們的項(xiàng)目添加一些初始數(shù)據(jù) 在init 中在初始化一下 slider

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(biāo)題滾動(dòng)到對(duì)應(yīng)位置// 五個(gè)參數(shù) 滾動(dòng)到元素時(shí)間水平偏移豎直偏移后兩個(gè)為true 則是中心位置最后一個(gè) 設(shè)置動(dòng)畫效果this.scrollmethod.scrollToElement(dom, null,

flex;flex-direction: column;width="360px",height="auto" />

其中silder有個(gè)方法就是 goToPage

this.slide.goToPage(index);

傳入頁碼自動(dòng)滾動(dòng)至對(duì)應(yīng)頁數(shù) 所用的變化都在watch 中實(shí)現(xiàn)，這樣保證了數(shù)據(jù)變化就可以觸發(fā) 實(shí)現(xiàn)了上下聯(lián)動(dòng)效果效果如下

內(nèi)容橫向滾動(dòng)效果

4.實(shí)現(xiàn)下拉刷新上拉加載更多

現(xiàn)在是水平方向有多個(gè)頁面要實(shí)現(xiàn)下拉刷新上拉加載，為了保證每個(gè)頁面的獨(dú)立性，在每個(gè)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(shè)置一下eventPassthrough:"horizontal" 保證水平方向不干擾別人 slider 也設(shè)置eventPassthrough:"vertical", 保證豎直方向不干擾別人。

實(shí)現(xiàn)下拉效果和加載更多效果在初始化的時(shí)候還需要設(shè)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(fù)問題：在頁面來回切換過程中發(fā)現(xiàn)下拉刷新的定時(shí)器沒有清除導(dǎo)致下拉刷新沒有重置因此在//初始化時(shí)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(fù)制即可使用！

用的sass 作為css的預(yù)編譯，作為demo 就沒分模塊化，也方便快速實(shí)現(xiàn)功能和改造，本來想弄githup上但是一想光pull 和npm 一下就很費(fèi)時(shí)間直接貼代碼好了，只要有sass 和 npm 一下better scroll 創(chuàng)建一個(gè)vue 復(fù)制進(jìn)去就可以跑起來感覺更方便一些！

手機(jī)pos機(jī)怎么弄

手機(jī)POS機(jī)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(jī)里面純乎輸入卡號(hào)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(jī)上輸入密碼，辦理時(shí)需要身份證和銀行卡就行了，審核成功后再在手瞎御機(jī)上安裝一個(gè)軟件就可以磨褲巖使用了，實(shí)時(shí)到帳。如果在深圳的話可以聯(lián)系我。

以上就是關(guān)于組裝pos機(jī)插件,編程中的技術(shù)積累 betterscroll組件再次封裝的知識(shí)，后面我們會(huì)繼續(xù)為大家整理關(guān)于組裝pos機(jī)插件的知識(shí)，希望能夠幫助到大家！
