vue实现下拉加载其实没那么复杂

<template> <div class="list-wrap">  <div class="content" ref="list" @scroll="onScroll">   <slot></slot>  </div>  <div class="loading" v-show="loading">正在加载数据......</div> </div></template><script lang='ts'>import { Component, Vue, Watch, Prop } from "vue-property-decorator";@Component({ components: {}})export default class extends Vue { @Prop() private loading!: boolean; private onScroll() {  const obj: any = this.$refs.list;  // clientHeight 视口高度 scrollTop 滚动条离顶部的高度 scrollHeight 列表内容的高度  if (obj.clientHeight + obj.scrollTop === obj.scrollHeight) {   this.$emit("toBottom");  } }}</script><style scoped lang="scss">.list-wrap { width: 100%; height: 100%; position: relative; .content {  width: 100%;  height: 100%;  overflow-y: scroll; } .loading {  position: absolute;  bottom: -20px;  width: 100%;  height: 20px;  color: #ffffff; }}::-webkit-scrollbar { // 去除滚动条边框 width: 0 !important;}::-webkit-scrollbar { width: 0 !important; height: 0;}</style>

<div class="body">   <m-list @toBottom="fetchNewData()" :loading="loading">    <code-info class="item" v-for="(item,index) in dataList" :key="index"></code-info>   </m-list></div> private dataList: any[] = [1, 2, 3, 4, 5, 6, 7, 8]; private loading: boolean = false; private fetchNewData() {  this.loading = true;  setTimeout(() => {   this.dataList.push(1, 2, 3);   const ref: any = this.$refs.vueLoad;   this.loading = false;  }, 1000); }
