网站建设网站需要什么网络营销的含义是什么

一、实现效果

二、实现思路

使用滚动事件监听器来检测用户是否滚动到底部，然后加载更多数据

1. 监听滚动事件。
2. 检测用户是否滚动到底部。
3. 加载更多数据。

三、案例代码

<div class="drawer-content"><div ref="loadMoreTrigger" class="load-more-trigger"></div><div v-if="isLoading" class="loading-button"><button type="primary" loading>加载中...</button></div>
</div>import { onBeforeUnmount, onMounted, ref, watch } from 'vue';const isLoading = ref(false);
const page = ref(1);const loadMoreData = async () => {if (isLoading.value) return;isLoading.value = true;// 模拟异步加载数据setTimeout(() => {const newItems: any = props.chartTableData?.slice(0, 10).map((item) => ({ ...item, id: item.id + page.value * 100 }));cardList.value = [...cardList.value, ...newItems];page.value += 1;isLoading.value = false;}, 1000);
};const handleScroll = () => {const drawerContent = document.querySelector('.drawer-content');if (drawerContent) {const { scrollTop, scrollHeight, clientHeight } = drawerContent;if (scrollTop + clientHeight >= scrollHeight - 10) {loadMoreData();}}
};onMounted(() => {const drawerContent = document.querySelector('.drawer-content');if (drawerContent) {drawerContent.addEventListener('scroll', handleScroll);}
});onBeforeUnmount(() => {const drawerContent = document.querySelector('.drawer-content');if (drawerContent) {drawerContent.removeEventListener('scroll', handleScroll);}
});.load-more-trigger {height: 1px;
}
.loading-button {text-align: center;margin-top: 10px;
}
