问题描述
选择条件后,上拉ScrollView加载多个页面数据,切换条件后会多次触发onScrollToLower,会导致加载多个页面的数据而不是page 1的数据

复现步骤

// RefreshList.tsx
ScrollToLower = () => {
    //滚动到底部事件
    this.props.onFooterRefresh();
  };
<View className="dragUpdataPage" style={{ '100vh' }}>
          <ScrollView
            onScrollToLower={this.ScrollToLower}
            scrollY
            scrollWithAnimation
          >
            {this.props.children}
          </ScrollView>
        </View>
// 调用
private onFooterRefresh = () => {
    console.log('onFooterRefresh'); // 切换条件多次触发
    const { page } = this.props.requirementService!.store;
    this.fetchList(page + 1);
  };
<RefreshList
            onFooterRefresh={this.onFooterRefresh}
          >
            <View>
              {list.map((item, index) => (
                  <RequirementItem
                    key={item.id}
                    data={item}
                    last={index < list.length - 1}
                  />
                ))}
            </View>
          </RefreshList>

期望行为
切换条件后只加载第一页的数据
