Code demo

Basic usage

The refresh event is triggered when the pull-down refresh is triggered, and synchronization or asynchronous operations can be performed in the callback function of the event, and the v-model is set to false when the operation is complete, indicating that the load is complete.

<van-pull-refresh v-model="isLoading" @refresh="onRefresh">
  <p>刷新次数: {{ count }}</p>
</van-pull-refresh>

import { Toast } from 'vant';

export default {
  data() {
    return {
      count: 0,
      isLoading: false
    }
  },
  methods: {
    onRefresh() {
      setTimeout(() => {
        Toast('刷新成功');
        this.isLoading = false;
        this.count++;
      }, 1000);
    }
  }
}

A successful prompt

The success-text allows you to set the top prompt file after a successful refresh

<van-pull-refresh
  v-model="isLoading"
  success-text="刷新成功"
  @refresh="onRefresh"
>
  <p>刷新次数: {{ count }}</p>
</van-pull-refresh>

Custom tips

The slot allows you to customize the prompts during the pull-down refresh process

<van-pull-refresh v-model="isLoading" :head-height="80" @refresh="onRefresh">
  <!-- 下拉提示，通过 scale 实现一个缩放效果 -->
  <img
    class="doge"
    slot="pulling"
    slot-scope="props"
    src="https://img.yzcdn.cn/vant/doge.png" rel="external nofollow"  rel="external nofollow" 
    :style="{ transform: `scale(${props.distance / 80})` }"
  >
  <!-- 释放提示 -->
  <img
    class="doge"
    slot="loosing"
    src="https://img.yzcdn.cn/vant/doge.png" rel="external nofollow"  rel="external nofollow" 
  >
  <!-- 加载提示 -->
  <img
    class="doge"
    slot="loading"
    src="https://img.yzcdn.cn/vant/doge-fire.jpg" rel="external nofollow" 
  >
  <p>刷新次数: {{ count }}</p>
</van-pull-refresh>
