How to modify the drop-down refresh style in Uniapp

In Uniapp, pull-down refresh is a very common function, but the default pull-down refresh style may not meet the application's UI design needs. Therefore, we need to modify the drop-down refresh style. This article will introduce how to modify the drop-down refresh style in Uniapp.

First of all, pull-down refresh in Uniapp is achieved by using the uni-scroll-view component. Therefore, we need to use this component to make pull-down refresh modifications.

The following are the specific steps to modify the pull-down refresh style of uni-scroll-view:

Step 1: Add the uni-scroll-view component in the template

In the template Add the uni-scroll-view component and add various attributes needed for pull-down refresh.

<template>
  <view>
    <uni-scroll-view class="scroll-view"
      :scroll-top="scrollTop"
      @scrolltolower="scrollToLower"
      @scroll="scroll"
      @refresh="refresh"
      :scroll-with-animation="scrollWithAnimation"
      :enable-back-to-top="enableBackToTop"
      :refresher-enabled="true"
      :refresher-threshold="45"
      :refresher-default-style="refresherDefaultStyle"
      :refresher-background-color="refresherBackgroundColor"
      :text-style="textStyle">

      <!-- 下拉刷新的容器组件 -->
      <view class="refresh-container">
        <view v-if="isRefreshing" class="loading-box">
          <loading class="loading" type="circular" size="23"></loading>
          <text class="loading-text">正在刷新...</text>
        </view>
        <view v-else class="arrow-icon-box">
          <image :src="arrowIconSrc" class="arrow-icon" :style="{transform: pullDownStyle}" />
          <text class="refresh-text">{{ refreshText }}</text>
        </view>
      </view>

      <!-- 加载更多的容器组件 -->
      <slot></slot>
      <view v-if="isLoadingMore" class="loading-more">{{ loadingMoreText }}</view>
    </uni-scroll-view>
  </view>
</template>

In the above template, we have used the refresher-enabled attribute and set it to true, thereby enabling the pull-down refresh feature.

Step 2: Add drop-down refresh style in style

Add various styles needed for drop-down refresh in style.

<style>
  .refresh-container {
    display: flex;
    flex-direction: column;
    justify-content: flex-end;
    align-items: center;
    height: 45px;
    line-height: 45px;
    color: #999;
  }

  .arrow-icon-box {
    display: flex;
    flex-direction: row;
    align-items: center;
    justify-content: center;
    height: 45px;
    line-height: 45px;
  }

  .arrow-icon {
    width: 23px;
    height: 23px;
  }

  .refresh-text {
    margin-left: 12px;
    font-size: 14px;
  }

  .loading-box {
    display: flex;
    flex-direction: row;
    align-items: center;
    height: 45px;
    line-height: 45px;
    color: #999;
  }

  .loading {
    margin-left: 12px;
    margin-right: 12px;
  }

  .loading-text {
    font-size: 14px;
  }
</style>

In the above style, we have modified the styles of drop-down refresh container components, arrow icons, refresh text, loading text and other elements.

Step 3: Add pull-down refresh data and events in the script

Add the data and events needed for pull-down refresh in the script.

<script>
  export default {
    data() {
      return {
        isRefreshing: false,
        refreshText: '下拉刷新',
        arrowIconSrc: 'static/img/arrow-down.png',
        pullDownStyle: 'rotate(0deg)',
      }
    },
    methods: {
      // 下拉刷新事件
      refresh() {
        this.isRefreshing = true;
        this.refreshText = '正在刷新';
        this.arrowIconSrc = 'static/img/loading.gif';
        this.pullDownStyle = 'rotate(360deg)';
        setTimeout(() => {
          this.isRefreshing = false;
          this.refreshText = '下拉刷新';
          this.arrowIconSrc = 'static/img/arrow-down.png';
          this.pullDownStyle = 'rotate(0deg)';
        }, 2000);
      },
      // 滚动事件
      scroll(e) {
        // 滚动时记录滚动位置
        this.scrollTop = e.detail.scrollTop;
      },
      // 滚动到底部事件
      scrollToLower() {
        if (!this.isLoadingMore) {
          this.isLoadingMore = true;
          this.loadingMoreText = '加载中...';
          setTimeout(() => {
            this.isLoadingMore = false;
            this.loadingMoreText = '上拉加载更多';
          }, 2000);
        }
      },
    },
  }
</script>

In the above event, we implemented functions such as pull-down to refresh and scroll to the bottom to load more.
