(编辑:jimmy 日期: 2024/11/18 浏览:3 次 )
本人正在基于 vue2.0 + webpack + es6 搭建前端架构,整理了部分插件,下面这个是下拉更新 上拉更多的,挺好用的,分享给大家。
直接上代码,不懂的多看几遍,下面我换会告诉大家如何使用。
<template lang="html"> <div class="yo-scroll" :class="{'down':(state===0),'up':(state==1),refresh:(state===2),touch:touching}" @touchstart="touchStart($event)" @touchmove="touchMove($event)" @touchend="touchEnd($event)" @scroll="(onInfinite || infiniteLoading) "> <section class="inner" :style="{ transform: 'translate3d(0, ' + top + 'px, 0)' }"> <header class="pull-refresh"> <slot name="pull-refresh"> <span class="down-tip">下拉更新</span> <span class="up-tip">松开更新</span> <span class="refresh-tip">更新中</span> </slot> </header> <slot></slot> <footer class="load-more"> <slot name="load-more"> <span>加载中……</span> </slot> </footer> </section> </div> </template> <script> export default { props: { offset: { type: Number, default: 40 }, enableInfinite: { type: Boolean, default: true }, enableRefresh: { type: Boolean, default: true }, onRefresh: { type: Function, default: undefined, required: false }, onInfinite: { type: Function, default: undefined, require: false } }, data() { return { top: 0, state: 0, startY: 0, touching: false, infiniteLoading: false } }, methods: { touchStart(e) { this.startY = e.targetTouches[0].pageY this.startScroll = this.$el.scrollTop || 0 this.touching = true }, touchMove(e) { if (!this.enableRefresh || this.$el.scrollTop > 0 || !this.touching) { return } let diff = e.targetTouches[0].pageY - this.startY - this.startScroll if (diff > 0) e.preventDefault() this.top = Math.pow(diff, 0.8) + (this.state === 2 "htmlcode"><template> <div> <v-scroll :on-refresh="onRefresh" :on-infinite="onInfinite"> <ul> <li v-for="(item,index) in listdata" >{{item.name}}</li> <li v-for="(item,index) in downdata" >{{item.name}}</li> </ul> </v-scroll> </div> </template> <script> import Scroll from './y-scroll/scroll'; export default{ data () { return { counter : 1, //默认已经显示出15条数据 count等于一是让从16条开始加载 num : 15, // 一次显示多少条 pageStart : 0, // 开始页数 pageEnd : 0, // 结束页数 listdata: [], // 下拉更新数据存放数组 downdata: [] // 上拉更多的数据存放数组 } }, mounted : function(){ this.getList(); }, methods: { getList(){ let vm = this; vm.$http.get('https://api.github.com/repos/typecho-fans/plugins/contents/').then((response) => { vm.listdata = response.data.slice(0,15); }, (response) => { console.log('error'); }); }, onRefresh(done) { this.getList(); done() // call done }, onInfinite(done) { let vm = this; vm.$http.get('https://api.github.com/repos/typecho-fans/plugins/contents/').then((response) => { vm.counter++; vm.pageEnd = vm.num * vm.counter; vm.pageStart = vm.pageEnd - vm.num; let arr = response.data; let i = vm.pageStart; let end = vm.pageEnd; for(; i<end; i++){ let obj ={}; obj["name"] = arr[i].name; vm.downdata.push(obj); if((i + 1) >= response.data.length){ this.$el.querySelector('.load-more').style.display = 'none'; return; } } done() // call done }, (response) => { console.log('error'); }); } }, components : { 'v-scroll': Scroll } } </script>以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
