Infinite Scroll 无限滚动 ​

滚动至底部时，加载更多数据。

ts
import { createApp } from 'vue'
import { InfiniteScroll } from '@szhn/dh-design-pc'

const app = createApp()
app.use(InfiniteScroll)

基础用法 ​

在要实现滚动加载的列表上添加 v-infinite-scroll，并赋值相应的加载方法，可实现滚动到底部时自动执行加载方法。

<template>
  <ul v-infinite-scroll="load" class="infinite-list" style="overflow: auto">
    <li v-for="i in count" :key="i" class="infinite-list-item">{{ i }}</li>
  </ul>
</template>

<script lang="ts" setup>
import { ref } from 'vue'

const count = ref(0)
const load = () => {
  count.value += 2
}
</script>

<style>
.infinite-list {
  height: 300px;
  padding: 0;
  margin: 0;
  list-style: none;
}
.infinite-list .infinite-list-item {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 50px;
  background: var(--el-color-primary-light-9);
  margin: 10px;
  color: var(--el-color-primary);
}
.infinite-list .infinite-list-item + .list-item {
  margin-top: 10px;
}
</style>

禁用加载 ​

<template>
  <div class="infinite-list-wrapper" style="overflow: auto">
    <ul
      v-infinite-scroll="load"
      class="list"
      :infinite-scroll-disabled="disabled"
    >
      <li v-for="i in count" :key="i" class="list-item">{{ i }}</li>
    </ul>
    <p v-if="loading">Loading...</p>
    <p v-if="noMore">No more</p>
  </div>
</template>

<script lang="ts" setup>
import { computed, ref } from 'vue'

const count = ref(10)
const loading = ref(false)
const noMore = computed(() => count.value >= 20)
const disabled = computed(() => loading.value || noMore.value)
const load = () => {
  loading.value = true
  setTimeout(() => {
    count.value += 2
    loading.value = false
  }, 2000)
}
</script>

<style>
.infinite-list-wrapper {
  height: 300px;
  text-align: center;
}
.infinite-list-wrapper .list {
  padding: 0;
  margin: 0;
  list-style: none;
}

.infinite-list-wrapper .list-item {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 50px;
  background: var(--el-color-danger-light-9);
  color: var(--el-color-danger);
}
.infinite-list-wrapper .list-item + .list-item {
  margin-top: 10px;
}
</style>
