如何封装了一个vue移动端下拉加载下一页数据的组件

<template>
 <div class="my-scroll" :class="[scrollState" ref="myScroll" @scroll.passive="onScroll($event)" @touchmove="onScroll($event)" >
  <!-- top -->
  <div class="scroll-list">
   <slot name='scrollList'></slot>
   <div class="scroll-bottom">
    <div v-if="state==1">
     <i><img :src="/UploadFiles/2021-04-02/Load">

使用




<template>
 <div id="app">
  <my-scroll class="scrolls" ref="myScroll" :on-pull="getList" :loaded="loaded" :scroll-state="scrollState">
   <div slot="scrollList">
   <div class="list" v-for="(item,index) in listData" :key="index">{{item.name}}</div>
   </div>
  </my-scroll>
 </div>
</template>
<script>
import myScroll from "./components/vue-scroll.vue";
import axios from 'axios'
export default {
 name: "app",
 data(){
 return{
  scrollState: true, // 是否可以滑动
  loaded: false,
  iPage: 1,
  listData:[],
  iPageSize: 10,
 }
 },
 methods: {
 getList(){
  this.$refs.myScroll.setState(1)
  let _this = this
  // ajax 请求
  axios.get('https://easy-mock.com/mock/5b90f971ce624c454133ee2d/scoll/datalist').then(function (response) {
   if (response.data.code == 200 && response.data.data.pagelist.length > 0 && !_this.loaded) {
    if (_this.iPage == 1) {
    _this.listData = response.data.data.pagelist
    } else {
    _this.listData.push(...response.data.data.pagelist)
    }
    _this.iPage++
    _this.$refs.myScroll.setState(2)
   } else {
    if (_this.iPage == 1) {
    _this.czListData = []
    }
    _this.loaded = true
    _this.$refs.myScroll.setState(3)
   } 
   })
   .catch(function (error) {
   console.log(error);
   });
  }

 },
 mounted () {
 this.getList() 
 },
 components: {
 myScroll
 }
};
</script>

<style scoped>
#app {
 font-family: "Avenir", Helvetica, Arial, sans-serif;
 -webkit-font-smoothing: antialiased;
 -moz-osx-font-smoothing: grayscale;
 text-align: center;
 color: #2c3e50;
 margin-top: 60px;
}
.scrolls{
 font-size:.24rem;
}
.list{
 height:.9rem;
 line-height: .9rem;
 margin-bottom:.1rem;
 border-bottom:1px solid #dedede;
