InfiniteScroll 无限滚动

滚动至底部时,加载更多数据。

基础用法

在要实现滚动加载的列表上上添加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 class="infinite-list" v-infinite-scroll="load" style="overflow:auto">
    <li v-for="i in count" class="infinite-list-item">{{ i }}</li>
  </ul>
</template>

<script>
  export default {
    data() {
      return {
        count: 0,
      }
    },
    methods: {
      load() {
        this.count += 2
      },
    },
  }
</script>

禁用加载


<template>
  <div class="infinite-list-wrapper" style="overflow:auto">
    <ul
      class="list"
      v-infinite-scroll="load"
      infinite-scroll-disabled="disabled"
    >
      <li v-for="i in count" class="list-item">{{ i }}</li>
    </ul>
    <p v-if="loading">加载中...</p>
    <p v-if="noMore">没有更多了</p>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        count: 10,
        loading: false,
      }
    },
    computed: {
      noMore() {
        return this.count >= 20
      },
      disabled() {
        return this.loading || this.noMore
      },
    },
    methods: {
      load() {
        this.loading = true
        setTimeout(() => {
          this.count += 2
          this.loading = false
        }, 2000)
      },
    },
  }
</script>
