uniapp implements how to add pull-down refresh and pull-up loading functions to the page

It is a very common requirement for Uniapp to implement pull-down refresh and pull-up loading. In this article, we will introduce in detail how to implement these two functions in Uniapp and give Provide specific code examples.

1. Implementation of the pull-down refresh function

1. In the pages directory, select the page where you need to add the pull-down refresh function and open the vue file of the page.
2. To add a pull-down refresh structure to the template, you can use uni's own pull-down refresh component uni-scroll-view. The code is as follows:

<template>
  <view>
    <uni-scroll-view class="refresh" :enable-back-to-top="true" @scrolltoupper="onRefresh">
      <view class="refresh__content">
        // 这里是页面的内容
      </view>
    </uni-scroll-view>
  </view>
</template>

3. Add the pull-down refresh logic code in the script. The code is as follows:

<script>
export default {
  data() {
    return {
      // 这里是页面的数据
    }
  },
  methods: {
    onRefresh() {
      // 这里是下拉刷新触发的逻辑代码
      // 在这里处理数据的刷新操作
      // 刷新完成后需要重置下拉刷新组件的状态
      // 例如：this.$refs.refreshRef.finishPullDown()
    }
  }
}
</script>

In this way, we have completed the implementation of the pull-down refresh function.

2. Implementation of more pull-up loading functions

1. To add more pull-up loading structures to the template of the page, you can use uni’s own pull-up loading componentuni-scroll-view, the code is as follows:

<template>
  <view>
    <uni-scroll-view class="list" :enable-back-to-top="true" @scrolltolower="onLoadMore">
      <view class="list__content">
        // 这里是列表的内容
      </view>
      <uni-loading v-if="loading" tip="加载中..."></uni-loading>
    </uni-scroll-view>
  </view>
</template>

2. Add pull-up loading more logic code in the script of the page, the code is as follows:

<script>
export default {
  data() {
    return {
      loading: false
    }
  },
  methods: {
    onLoadMore() {
      // 这里是上拉加载更多触发的逻辑代码
      // 在这里处理数据的加载操作
      // 加载完成后需要重置上拉加载组件的状态
      // 例如：this.$refs.listRef.finishPullUp()
    }
  }
}
</script>

In this way, we have completed the implementation of more pull-up loading functions.

Summary:

Through the above steps, we can easily implement pull-down to refresh and pull-up to load more functions in Uniapp. However, this is just the basic implementation. The specific code may vary depending on the needs of the specific business, and can be adjusted accordingly according to the specific situation. Hope this article helps you!
