// 部分代码片段
import InfiniteScroll from 'react-infinite-scroller';
import {Scrollbars} from 'react-custom-scrollbars';
//初始的state的状态
this.state = {
loading: true,
hasMore: true,
pageNum: 1,
pageSize: 20,
total: 0,
data: [],
};
// 获取下一页信息
getMore = () => {
if (this.state.total === this.state.data.length) {
return;
}
this.setState({
loading: true,
pageNum: this.state.pageNum + 1
}, () => {
this.initData(); //请求数据接口
});
}
//组件调用
<Scrollbars id='list-scrollbars' style={{height: "calc(100vh - 260px)"}} autoHide >
<InfiniteScroll
className="list-contents"
initialLoad={false}
pageStart={0}
loadMore={this.getMore.bind(this)}
hasMore={!this.state.loading && this.state.hasMore}
useWindow={false}
>
{this.renderItemList(data)} // Tip:内部元素不要加高度以及overflow:auto等属性!!!!
{total === data.length && data.length > 4 ? <div className="end-text">所有数据已看完</div> : ""}
</InfiniteScroll>
{this.state.loading ? <div style={{position: 'relative', marginTop: 30}}><Loading/></div> : ""} // 滚动加载状态的loading状态
</Scrollbars>
效果说明:
分页取数据,一页20条为例,滚动完20条之后就加载下一页~
