npm 详情：vue-virtual-scroller - npm (npmjs.com)

这里我使用的是RecycleScroller。

App.vue

<template><RecycleScrollerclass="scroller":items="items":item-size="54"v-slot="{ item }"><list-item :item="item"></list-item></RecycleScroller>
</template><script>
import {RecycleScroller} from 'vue-virtual-scroller'
import 'vue-virtual-scroller/dist/vue-virtual-scroller.css'
import ListItem from "@/components/ListItem.vue";// items 是一个对象数组， item 传递给 ListItem 组件 是包含了对象数组的对象
var items = []
for (let i = 0; i < 10000; i++) {items.push({id: i + 1,name: 'User ' + (i + 1),})
}
export default {components: {ListItem,RecycleScroller},data() {return {items: items}}
}
</script><style scoped>
.scroller {height: 50vh;width: 50vw;background-color: #f5f5f5;padding: 10px;}
</style>

ListItem.vue

<script>export default {props: {item: Object}
}
</script><template><div class="list-item"><span>id{{item.id}}</span><span>name{{item.name}}</span><span>age{{item.count}}</span></div>
</template><style scoped>
.list-item {text-align: center;height: 54px;padding: 1em;box-sizing: border-box;display: grid;grid-template-columns: repeat(3, 1fr);box-shadow: 0 0 3px rgba(0, 0, 0, 0.5);
}
</style>
