To create a component that loads the next page of data, you can follow these steps:

  1. Create a component called LoadMore that includes a button or another interactive element to trigger the action of loading the next page of data. For example:
<template>
  <button @click="loadNextPage">加载更多</button>
</template>

<script>
export default {
  methods: {
    loadNextPage() {
      // 在这里触发加载下一页数据的操作
      // 可以通过调用父组件传递的方法来实现
      this.$emit('load-next-page');
    }
  }
}
</script>
  1. Import the LoadMore component in the parent component and pass a method to load the next page of data.
<template>
  <div>
    <!-- 显示当前页面数据 -->
    <ul>
      <li v-for="item in items" :key="item.id">{{ item.name }}</li>
    </ul>
    
    <!-- 加载下一页数据的按钮 -->
    <LoadMore @load-next-page="loadNextPage"></LoadMore>
  </div>
</template>

<script>
import LoadMore from './LoadMore.vue';

export default {
  components: {
    LoadMore
  },
  data() {
    return {
      items: [], // 存储当前页面数据
      page: 1 // 当前页数
    };
  },
  methods: {
    loadNextPage() {
      // 在这里加载下一页数据的方法
      // 可以通过接口请求或其他方式获取数据
      // 在成功获取数据后，将数据添加到 items 中
      this.page++;
      // 此处为示例，你需要根据实际情况进行修改
      this.items = this.items.concat(newData);
    }
  }
}
</script>

So, when the user clicks the button in the LoadMore component, the loadNextPage method in the parent component will be called, thus achieving the function of loading the next page of data. You can modify the logic for loading data in the LoadMore and parent components according to specific requirements.
