vue2.0 移动端实现下拉刷新和上拉加载更多的示例

(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>

  onInfinite: {

  return {
   top: 0,
   state: 0,
   startY: 0,
   touching: false,
   infiniteLoading: false
  }
 },

  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">
