mintui是饿了么团队针对vue开发的移动端组件库，方便实现移动端的一些功能,这里主要给大家介绍vue2 mint-ui loadmore实现下拉刷新,上拉更多功能，具体代码如下所示：
<template>
<div 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>
<div class="loading-background" :style="{ transform: 'scale3d(' + moveTranslate + ',' + moveTranslate + ',1)' }">
translateScale : {{ moveTranslate }}
</div>
<div class="page-loadmore-wrapper" ref="wrapper" :style="{ height: wrapperHeight + 'px' }">
<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>
<div slot="top" class="mint-loadmore-top">
