也是公司项目 ，内部app的资讯模块整改，改是不可能改的，之前还是用jquery。感觉越改越混乱，还是重做。就仿着今日头条、等资讯页面做了一个dome，话不多说，先看效果!
效果看完，感觉还行的话，接着就往下看开启爬坑之路！
先打一个无偿广告 上图的gif 是通过LICEcap 软件录屏制作的！下载地址：官网地址，支持window mac ，无插件 无广告 完全免费！确实好用，比起国内的动不动就要会员才能导出的***软件要好的多
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 aaa@qq.com -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
先是进行页面布局吧
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**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 navlist
this.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: 100%;
height: 100%;
overflow: hidden;
background-color: rgba(247, 247, 247, 1);
.topcontent {
z-index: 999;
display: flex;
.tranbox{
width: 10px;
background-color: #fff;
z-index: 999;
}
.tab{
background-color: #fff;
flex: 1;
overflow: hidden;
.tabitems{
display: inline-flex;
width: auto;
.tabitem{
flex: 1;
font-size: 15px;
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: 60%;
height: 3px;
background-color: #F14D44;
}
}
}
}
.additem{
height: 100%;
width: 45px;
display: flex;
justify-content: center;
align-items: center;
background-color: #fff;
font-size: 20px;
line-height: 24px;
padding:10px 0;
color: #888;
box-shadow: 0 -5px 5px #ddd;
z-index: 999;
}
}
}
</style>
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
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
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 {

],
activeitem: {},
};
},
watch:{
activeitem:function(val) {
let idx;
this.navlist.map((item,index)=>{
if(item.id == val.id){
idx = index
}
}
);
this.changetitle(val,idx);
}
},

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
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**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！

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！
