Infiniteloading组件

介绍

列表滚动到底部自动加载更多数据。

安装

  import { createApp } from 'vue';
  import { InfiniteLoading } from '@nutui/nutui';
  const app = createApp();
  app.use(InfiniteLoading);

代码演示

基础用法

<ul class="infiniteUl" id="scroll">
    <nut-infiniteloading
        containerId = 'scroll'
        :use-window='false'
        :has-more="hasMore"
        @load-more="loadMore"
    >
        <li class="infiniteLi" v-for="(item, index) in defultList" :key="index"></li>
    </nut-infiniteloading>
</ul>

setup() {
    const hasMore = ref(true);
    const data = reactive({
      defultList: []
    });
    const loadMore = done => {  
      setTimeout(() => {
        const curLen = data.defultList.length;
        for (let i = curLen; i < curLen + 10; i++) {
          data.defultList.push(`${i}`);
        }
        if (data.defultList.length > 30) hasMore.value = false;
        done()
      }, 500);
    };
    const init = () => {
      for (let i = 0; i < 10; i++) {
        data.defultList.push(`${i}`);
      }
    }
    onMounted(() => {
      init()
    });
    return { loadMore, hasMore, ...toRefs(data) };
}

下拉刷新

<ul class="infiniteUl" id="refreshScroll">
  <nut-infiniteloading
    pull-icon="JD"
    container-id="refreshScroll"
    :use-window="false"
    :is-open-refresh="true"
    :has-more="refreshHasMore"
    @load-more="refreshLoadMore"
    @refresh="refresh"
  >
    <li
      class="infiniteLi"
      v-for="(item, index) in refreshList"
      :key="index"
      ></li
    >
  </nut-infiniteloading>
</ul>

setup() {
    const refreshHasMore = ref(true);
    const data = reactive({
      refreshList: []
    });
    const refreshLoadMore = done => {
      setTimeout(() => {
        const curLen = data.refreshList.length;
        for (let i = curLen; i < curLen + 10; i++) {
          data.refreshList.push(
            `${i}`
          );
        }
        if (data.refreshList.length > 30) refreshHasMore.value = false;
        done()
      }, 500);
    };
    const refresh = (done) => {
      setTimeout(()=>{
        Toast.success('刷新成功');
        done()
      },1000)
    }
    const init = () => {
      for (let i = 0; i < 10; i++) {
        data.refreshList.push(`${i}`);
      }
    }
    onMounted(() => {
      init()
    });
    return { refreshLoadMore, refreshHasMore, refresh, ...toRefs(data) };
}

自定义加载文案

<ul class="infiniteUl" id="customScroll">
    <nut-infiniteloading
        container-id = 'customScroll'
        :use-window='false'
        :has-more="customHasMore"
        @load-more="customLoadMore"
    >
        <li class="infiniteLi" v-for="(item, index) in customList" :key="index"></li>
        <template v-slot:loading>
            <div class="loading">
                <span>加载中...</span>
            </div>
        </template>
        <template v-slot:unloadMore>
            <div class="unload-more">没有数据啦 ~~</div>
        </template>
    </nut-infiniteloading>
</ul>

setup() {
    const customHasMore = ref(true);
    const data = reactive({
      customList: ['']
    });
    const customLoadMore = done => {
      setTimeout(() => {
        const curLen = data.customList.length;
        for (let i = curLen; i < curLen + 10; i++) {
          data.customList.push(`${i}`);
        }
        if (data.customList.length > 30) customHasMore.value = false;
        done()
      }, 500);
    };
    const init = () => {
      for (let i = 0; i < 10; i++) {
        data.customList.push(`${i}`);
      }
    }
    onMounted(() => {
      init()
    });
    return { customHasMore, customLoadMore,...toRefs(data) };
}
