官方文档：

ElementUI —— InfiniteScroll 无限滚动

https://element.eleme.cn/#/zh-CN/component/infiniteScroll

 

根据文档这部分，写了我的代码，开始长下面这样子…结果发现了一个问题，就是进入页面之后像是  infinite-scroll-disabled和infinite-scroll-immediate没有生效似的，页面疯狂调用onLoad函数。

<div
  class="left"
  v-infinite-scroll="onLoad()"
  infinite-scroll-disabled="disabled"
  infinite-scroll-immediate="false"
>
  <div v-for="item in demoList" :key="item.commentId"
    <list-item :item="item" ></list-item>
  </div>
  <p v-if="listParams.loading">Loading...</p>
  <p v-if="listParams.finished">No More</p>
</div>

度娘许久无果，于是逐字对比官方样例……最终将

v-infinite-scroll="onLoad()"

改为

v-infinite-scroll="onLoad"

成功解决问题…

 

放一个能正常运行的代码上来

<template>
  <div class="container">
    <div
      class="left"
      v-infinite-scroll="onLoad"
      infinite-scroll-disabled="disabled"
      infinite-scroll-immediate="false"
    >
      <div v-for="item in demoList" :key="item.commentId">
        <list-item
          :item="item"
        ></list-item>
      </div>
      <p v-if="listParams.loading">Loading...</p>
      <p v-if="listParams.finished">No More</p>
    </div>
  </div>
</template>
