vux scroller 向上刷新加載數據

研究了一下如何使用vux 的向上刷新

自己熟悉js滾動到底加載的同窗應該沒什麼問題

主要是對思路的理解

當頁面第一次加載的時候isEmpty爲true，觸發getNewsList（true）

當滾動到底部的時候會觸發selPullUp方法這個時候isEmpty爲false

<template>
  <div>
    <scroller v-show="isShow" v-model="scrollerStatus" height="-46" lock-x scrollbar-y ref="scroller" :bounce="isbounce"
              :use-pullup="showUp" :pullup-config="upobj" @on-pullup-loading="selPullUp">
      <div class="box2">
        <div class="weui-panel weui-panel_access">
          <div class="weui-panel__hd">圖文組合列表</div>
          <div v-for="list, index in lists" class="weui-panel__bd">
            <a href="javascript:void(0);" class="weui-media-box weui-media-box_appmsg">
              <div class="weui-media-box__hd">
                <img class="weui-media-box__thumb" :src="list.pic" alt="">
              </div>
              <div class="weui-media-box__bd">
                <h4 class="weui-media-box__title">{{list.title}}</h4>
                <p class="weui-media-box__desc">由各類物質組成的巨型球狀天體，叫作星球。星球有必定的形狀，有本身的運行軌道。</p>
