van-pull-refresh配合van-list写法

好的，下面是使用 van-pull-refresh 和 van-list 的示例代码：

<template>
  <van-pull-refresh v-model="refreshing" @refresh="onRefresh">
    <van-list :loading="loading" :finished="finished" :error="error" @load="onLoad">
      <van-cell v-for="(item, index) in list" :key="index">{{ item }}</van-cell>
    </van-list>
  </van-pull-refresh>
</template>

<script>
export default {
  data() {
    return {
      refreshing: false,
      loading: false,
      finished: false,
      error: false,
      list: [],
      page: 1,
      limit: 10
    };
  },
  methods: {
    onRefresh() {
      this.refreshing = true;
      setTimeout(() => {
        this.page = 1;
        this.list = ['Item 1', 'Item 2', 'Item 3'];
        this.finished = false;
        this.refreshing = false;
      }, 1000);
    },
    onLoad() {
      if (this.loading || this.finished) {
        return;
      }
      this.loading = true;
      setTimeout(() => {
        if (this.list.length >= 40) {
          this.finished = true;
        } else {
          this.page++;
          this.list.push(`Item ${this.page * this.limit - 8}`, `Item ${this.page * this.limit - 7}`, `Item ${this.page * this.limit - 6}`, `Item ${this.page * this.limit - 5}`, `Item ${this.page * this.limit - 4}`, `Item ${this.page * this.limit - 3}`, `Item ${this.page * this.limit - 2}`, `Item ${this.page * this.limit - 1}`, `Item ${this.page * this.limit}`);
        }
        this.loading = false;
      }, 1000);
    }
  }
};
</script>

在这个示例中，我们使用 van-pull-refresh 包裹 van-list，并且监听其 @refresh 事件来触发下拉刷新。同时，van-list 组件中的一些属性（如 loading、finished、error）和事件（如 @load）可以用于控制和监听列表的加载情况。在 onRefresh 和 onLoad 方法中，我们可以根据需要进行数据的请求和更新。
