组装pos机插件

也是组装中的组件再次公司项目 ，内部app的机技术积累资讯模块整改，改是插件不可能改的，之前还是编程用jquery。感觉越改越混乱，封装还是组装中的组件再次重做。就仿着今日头条、机技术积累等资讯页面做了一个dome，插件话不多说，编程先看效果!

效果图

效果看完，封装感觉还行的话，接着就往下看开启爬坑之路！

一、效果分析

看起来好像很常见，但是这个整体效果完成，对better scroll就比较熟悉了 做平常的滚动导航列表、轮播图、下拉刷新、上拉加载等ui模板都应该小kiss了。页面主要也就三个功能

顶部的可滑动导航列表中间的可滑动切换页 和导航列表有联动效果每页列表页都支持下拉刷新、上拉加载二、功能实现

1.插件安装

基于vue 和better scroll的项目，用vue cli 安装vue的环境搭建 这一块就不多说

better scroll的安装

npm install better-scroll@next -S

使用的话就比较简单

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)},}

使用的话也就是配置参数 对于这些参数详细解释就 分享一下api链接http://ustbhuangyi.github.io/better-scroll/doc/api.html

重要的标记一下：

一类是属性 在new的时候传入的 如scrollY:true 设置竖直方向可以滚动

一类是方法 就是在用户操作过程中可以调用该方法 如scroll 就是页面滚动中触发的，调用语法如下

this.bscroll.on('scroll', this.scrollHandler)scrollHandler(pos) {console.log(pos.y)},//上面为实时打印滚动的位置案例eventPassthrough

在属性上 这里要着重介绍 eventPassthrough属性！该属性默认值为'' 可以设置'vertical'、'horizontal'简单解释一下 当eventPassthrough 设置vertical 时 该实例 只会相应水平的滑动事件 竖直方向事件将不会影响它如咱们案例中的 左右切换和下拉刷新就必须设置该属性 ，不让相互影响 整个页面滑动效果就很卡顿

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

在放方法上也介绍一下scrollToElement，就是滚动到指定元素 ，五个参数（滚动到哪个对象 所需时间 x偏移 y偏移 动画效果）x偏移和y偏移 设置为true是 就会滚动到该元素中心位置

2.顶部滚动导航实现

也提一下滚动原理 虽然黄佚老师讲的很详细了，但是还是提一下，这个主要就是为了页面如何布局，内容区域大于wepper 才可以触发滚动，因此必须控制wrpper的大小，不能让它的大小让子元素撑开

滚动原理

先是进行页面布局吧

顶部滚动

顶部这一块红色标出的就是wrapper 大小固定 ，绿色的就是内容部分 可滚动；

而红色区域的大小就是屏幕的宽度减去两边的宽度 这个实现可以用flex 实现 可以用aclc实现 个人还是倾向于flex

布局完成之后就是 进行better scroll的初始化 对于这个实现就是 需要在激活状态下滚动至该元素的最中间直接用scrollToElement实现 整体代码如下：

<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:'要闻', action:'', type:'', from:'ezx',id:1},{title:'7*24', action:'', type:'', from:'ezx',id:2},{title:'自选股', action:'', type:'', from:'ezx',id:3},{title:'公司研报', action:'', type:'', from:'zz',id:4},{title:'行业研究', action:'', type:'', from:'zz',id:5},{title:'新三板新闻', action:'', type:'', from:'zz',id:6},{title:'期货研究', 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.$nextTick(()=>{//设置顶部滚动 navlistthis.scrollmethod = new BScroll(this.$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(() => {//标题滚动到对应位置// 五个参数 滚动到元素 时间 水平偏移 竖直偏移 后两个为true 则是中心位置 最后一个 设置动画效果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" />

复制代码就可以实现以下效果 算是一个 简单的滚动导航条了吧

顶部滚动效果

2. 滑动切换slider实现

用better scroll实现slider也是相当方便 直接就slider这个对象属性，初始化时候添加进来就好，而这个页面布局如下

内容横向滑动原理

根据咱们的项目 添加一些初始数据 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:'要闻', action:'', type:'',

idx;this.navlist.map((item,index)=>{if(item.id == val.id){idx = index}});this.changetitle(val,idx);}},created(){let data = {"code":0,"message":"SUCCESS","data":[{"item_title":"央行开展1年期MLF操作3000亿元

'vertical',scrollX: true,scrollY: false,preventDefault: false});//设置轮播页面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(() => {//标题滚动到对应位置// 五个参数 滚动到元素 时间 水平偏移 竖直偏移 后两个为true 则是中心位置 最后一个 设置动画效果this.scrollmethod.scrollToElement(dom, null, true, true);this.scrollmethod.refresh();//详情页滚动到对应页面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有个方法就是 goToPage

this.slide.goToPage(index);

传入页码 自动滚动至对应页数 所用的变化都在watch 中实现，这样保证了数据变化就可以触发 实现了上下联动效果 效果如下

内容横向滚动效果

4.实现下拉刷新 上拉加载更多

现在是水平方向有多个页面 要实现下拉刷新 上拉加载，为了保证每个页面的独立性，在每个页面激活后 给该页面增加该效果，就在watch中添加，为了防止其他页面干扰 切换前先清除下拉 scroll 为了防止和slider干扰 设置一下eventPassthrough:"horizontal" 保证水平方向不干扰别人 slider 也设置eventPassthrough:"vertical", 保证竖直方向不干扰别人。

实现下拉效果和加载更多效果在初始化的时候还需要设置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)//修复问题：在页面来回切换过程中 发现下拉刷新 的定时器没有清除 导致 下拉刷新没有重置 因此在//初始化时加了一下判断initscrldata(){this.loadingtxt='下拉刷新';this.dragTip={text:"释放刷新",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;},

最终代码如下。复制即可使用！

scoped>.page{display: flex;flex-direction: column;width="360px",height="auto" />

用的sass 作为css的预编译，作为demo 就没分模块化，也方便快速实现功能 和改造，本来想弄githup上 但是一想光pull 和npm 一下就很费时间 直接贴代码好了 ，只要有sass 和 npm 一下better scroll 创建一个vue 复制进去就可以跑起来 感觉更方便一些！

手机pos机怎么弄

手机POS机分为带刷卡头的和不带刷卡头的，不带卡头的是直接在手机里面纯乎输入卡号和密码就可以了，带卡头的需要直接用卡头刷卡然后在手机上输入密码，申请时需要身份证和银行卡就行了，审核成功后再在手瞎御机上安装一个软件就可以磨裤岩使用了，实时到帐。如果在深圳的话可以联系我。

以上就是关于组装pos机插件,编程中的技术积累 betterscroll组件再次封装的知识，后面我们会继续为大家整理关于组装pos机插件的知识，希望能够帮助到大家！
