<template>
  <ul>
    <li v-for="item in dataList" :key="item.id">{{ item.title }}</li>
  </ul>
</template>

<script>
export default {
  props: ['dataList']
}
</script>

<template>
  <div>
    <button @click="handlePreviousPage">上一页</button>
    <span>{{ currentPage }}/{{ totalPage }}</span>
    <button @click="handleNextPage">下一页</button>
  </div>
</template>

<script>
export default {
  props: ['currentPage', 'totalPage'],
  methods: {
    handlePreviousPage() {
      this.$emit('previousPage')
    },
    handleNextPage() {
      this.$emit('nextPage')
    }
  }
}
</script>

<template>
  <div>
    <data-display :dataList="currentData"></data-display>
    <pagination
      :currentPage="currentPage"
      :totalPage="totalPage"
      @previousPage="handlePreviousPage"
      @nextPage="handleNextPage"
    ></pagination>
  </div>
</template>

<script>
import DataDisplay from './DataDisplay'
import Pagination from './Pagination'

export default {
  data() {
    return {
      dataList: [],
      currentPage: 1,
      totalPage: 0
    }
  },
  components: {
    DataDisplay,
    Pagination
  },
  computed: {
    currentData() {
      // 根据当前页码获取当前页的数据

    }

    // 获取总页数
    // ...

  mounted() {
    // 监听滚动事件，在滚动到底部时加载下一页数据
    window.addEventListener('scroll', this.handleScroll)
