example

Install

或

yarn add react-scroll-mobile

Usage

import Scroll from 'react-scroll-mobile'

const timeout = delay => new Promise(resolve => setTimeout(resolve,delay));

class App extends Component {

  state = {
    list:[],
    noMore: false
  }

  pageIndex = 1;

  componentDidMount(){
    //首次加载时，可以主动触发下拉加载动效，更炫酷
    this.scrollRef.pullDownRefresh(this.pullDownRefresh)
  }

  pullDownRefresh = async ()=>{
    this.pageIndex = 1;
    await this.getData();
  };

  pullUpLoad = async ()=>{
    this.pageIndex ++;
    await this.getData();
  };

  getData = async ()=>{
    //模拟请求和数据
    await timeout(1000);
    let res = [0,1,2,3,4,5,6,7,8,9];
    // 模拟没有数据了 
    if(this.pageIndex > 4 )res = [];

    const list = this.pageIndex === 1 ? res : this.state.list.concat(res);
    this.setState({ 
      list,
      noMore: res.length === 0 
    })
  }

  render() {
    const { list, noMore } = this.state;

    return (
      <div className='list'>
        <Scroll
          ref={el=> this.scrollRef = el}
          pullDownRefresh={this.pullDownRefresh}
          pullUpLoad={this.pullUpLoad}
          noMore={noMore}
          backTop
        >
          <ul>
            {
              list.map((item,index)=><li key={index}>数据数据数据数据{index}</li>)
            }
          </ul>
        </Scroll>
      </div>
    );
  }
}

export default App;

API

选项

属性	类型	默认值	说明
pullDownRefresh	Function	null	下拉刷新时的回调函数,需要返回一个Promise来获取刷新状态,resolve刷新成功，reject刷新失败,建议直接使用async await
pullUpLoad	Function	null	上拉加载时的回调函数,需要返回一个Promise来获取加载状态,resolve加载成功，reject加载失败,建议直接使用async await
noMore	Boolean	false	上拉加载时，是否还有更多数据
noMoreTip	String/ReactComponent	'我是有底线的'	上拉加载时，没有更多数据的提示语
backTop	Boolean/ReactComponent	false	右下角返回顶部组件，设置为true时显示自带的组件，设置为ReactComponent是即使用自定义的返回顶部组件替换
