      style="height: 100%; overflow-y: scroll;"
      :size="list.length"

      @tobottom="listToBottom"
    >
    </vue-virtual-scroll-list>
  </div>
</template>

<script>
import { defineComponent, ref } from 'vue';
import VueVirtualScrollList from 'vue3-virtual-scroll-list';
import itemComponent from "./itemComponent.vue"
export default defineComponent({
  components: {
    VueVirtualScrollList,
    
  },
  setup() {
    const list = ref([]);
    const listToBottom = () => {
      console.log('到底了哦');
    }
    const content = ()=> {
      for(let i = 0; i < 100; i++){
        const obj = {id: i, name: `人员${i}`, sex: i % 2 === 0 ? '男' : '女'};
        list.value.push(obj) 
      }
    }
    onMounted(()=>{
      content()
    })
    return {
      list,
      itemComponent,
      address:{ province:'江苏',city:'南京' },
      basisInfo:[{age:20}],
      listToBottom
    };
  },
});
</script>

<style>
.container {
  height: 500px;
}

.scroll-list {
  width: 100%;
}

.list-item {
  height: 50px;
  line-height: 50px;
  border-bottom: 1px solid #ccc;
}
.container ::-webkit-scrollbar {
  width: 0px; /** 设置滚动条的宽度 */
  background-color: transparent;
}

.container ::-webkit-scrollbar-thumb {
  background-color: transparent;
}

.container ::-webkit-scrollbar-track {
  background-color: transparent;
}

.container {
  scrollbar-width: thin;
  scrollbar-color: transparent transparent;
}
</style>

component / itemComponent.vue

<template>
  <div>
    编号：{{ index }} <br/>
    姓名：{{ source.name }}<br/> 
    年龄：{{basisInfo[0].age}}<br/>
    地址：{{address.province}}-{{address.city}} <br />
    <div v-if="source.sex === '男'">
      {{ source.sex }}
    </div>
    <hr/>
  </div>
</template>

<script>
  export default {
    name: 'item-component',
    props: {
      index: { 
        type: Number
      },
      source: { 
        type: Object,
        default () {
          return {}
        }
      },
      address:{
        type: Object,
        default () {
          return {}
        }
      },
      basisInfo:{
        type: Array,
        default () {
          return []
        }  
      }
    },
    mounted(){}
  }
</script>

使用组件

<List></List>

import List from "./component/List.vue"
export default {
  name: "AboutPage",
  components: {
    List
  },
}
