mintui is a mobile component library developed by the Ele.me team for vue to facilitate the implementation of some mobile functions. Here we mainly introduce vue2 mint-ui loadmore to implement pull-down refresh and pull-up for more functions. The specific code As shown below:

<template>
 <p class="page-loadmore">
  <h1 class="page-title">Pull up</h1>
  <p class="page-loadmore-desc">在列表底部, 按住 - 上拉 - 释放可以获取更多数据</p>
  <p class="page-loadmore-desc">translate : {{ translate }}</p>
  <p class="loading-background" :style="{ transform: &#39;scale3d(&#39; + moveTranslate + &#39;,&#39; + moveTranslate + &#39;,1)&#39; }">
   translateScale : {{ moveTranslate }}
  </p>
  <p class="page-loadmore-wrapper" ref="wrapper" :style="{ height: wrapperHeight + &#39;px&#39; }">
   <mt-loadmore :top-method="loadTop" @translate-change="translateChange" @top-status-change="handleTopChange"    :bottom-method="loadBottom" @bottom-status-change="handleBottomChange" :bottom-all-loaded="allLoaded" ref="loadmore">
    <ul class="page-loadmore-list">
     <li v-for="item in list" class="page-loadmore-listitem">{{ item }}</li>
    </ul>
    <p slot="top" class="mint-loadmore-top">
     <span v-show="topStatus !== &#39;loading&#39;" :class="{ &#39;is-rotate&#39;: topStatus === &#39;drop&#39; }">↓</span>
     <span v-show="topStatus === &#39;loading&#39;">
      <mt-spinner type="snake"></mt-spinner>
     </span>
    </p>
    <p slot="bottom" class="mint-loadmore-bottom">
     <span v-show="bottomStatus !== &#39;loading&#39;" :class="{ &#39;is-rotate&#39;: bottomStatus === &#39;drop&#39; }">↑</span>
     <span v-show="bottomStatus === &#39;loading&#39;">
