This article introduces you to loading more at the bottom of vue through example code. The code is simple and easy to understand, very good, and has certain reference value. Friends in need can refer to it

The effect to be achieved is as follows:

<template>
 <p class="newsList">
  <p v-for="(items, index) in newsList">
   <p class="date">{{showDay(index)}}</p>
   <p class="list" >
    <ul>
     <li class="list-item" v-for="item in items">
      <span class="text">{{item.title}}</span>
      <img  class="image lazy"  src="/static/imghwm/default1.png"  data-src="attachImageUrl(item.images[0])"  : / alt="About loading more code at the bottom of vue" >
     </li>
    </ul>
   </p>
  </p>
  <p class="infinite-scroll" v-show="loading">
   <svg class="loader-circular" viewBox="25 25 50 50">
    <circle class="loader-path" cx="50" cy="50" r="20" fill="none" stroke="rgb(53, 157, 218)" stroke-width="5"></circle>
   </svg>
   <span class="infinite-scroll-text">{{tips}}</span>
  </p>
 </p>
