问题描述

局部滚动条往下滑动时触发下拉刷新

解决方案：

提示：这里填写该问题的具体解决方案：
van-pull-refresh 有 disabled 属性，可以控制是否禁用下拉刷新，通过监听touchmove和touchend事件获取局部滚动高度scrollTop，然后监听滚动高度scrollTop，滚动高度大于0时将van-pull-refresh 的 disabled 属性设置为true，禁用下拉刷新，当滚动高度scrollTop回到0的时候再将 disabled 属性设置为false.

<template>
        <van-pull-refresh
          v-model="refreshing"
          :disabled="isRefreshDisable"
          @refresh="onRefresh"
        >
          <van-list
            v-if="worlOrderList.length >= 0"
            v-model="loading"
            :finished="finished"
            finished-text="没有更多了"
            @load="onLoad"
          >
            <div v-for="(item, index) in worlOrderList" :key="index">
              {{ item.name }}
            </div>
          </van-list>
          <div v-else class="no-data">
            暂无数据
          </div>
        </van-pull-refresh>
      </template>
