Update

之前没有对请求异常情况做处理，当获取列表失败后，会一直停留在 loading 状态，没有机会再尝试加载。
现在在 props 添加 error，指定加载失败时的文案显示，显示位置和 loader 相同。设置 error 时，自动加载效果会暂时失效，需要手动点错误文案加载。加载成功后会继续支持滚动加载。

The request exception condition has not been processed before. When the data request fails, it will stay in the loading state and there is no chance to try to load again.
Now add error to props to specify the tips of error when the load fails, and the display position is the same as loader. When error is set, the autoloading effect will temporarily become invalid, and you need to manually click the tips to load data. infinite scroller load will continue to be supported after successful loading.

Installation

npm install react-infinite-scroller-improve --save

yarn add react-infinite-scroller-improve

How to use

import InfiniteScroll from 'react-infinite-scroller';

Window scroll events

<InfiniteScroll
    pageStart={0}
    loadMore={loadFunc}
    hasMore={true || false}
    loader={<div className="loader" key={0}>Loading ...</div>}
>
    {items} // <-- This is the content you want to load
</InfiniteScroll>

DOM scroll events

<div style="height:700px;overflow:auto;">
    <InfiniteScroll
        pageStart={0}
        loadMore={loadFunc}
        hasMore={true || false}
        loader={<div className="loader" key={0}>Loading ...</div>}
        useWindow={false}
    >
        {items}
    </InfiniteScroll>
</div>

Custom parent element

You can define a custom parentNode element to base the scroll calulations on.

<div style="height:700px;overflow:auto;" ref={(ref) => this.scrollParentRef = ref}>
    <div>
        <InfiniteScroll
            pageStart={0}
            loadMore={loadFunc}
            hasMore={true || false}
            loader={<div className="loader" key={0}>Loading ...</div>}
            useWindow={false}
            getScrollParent={() => this.scrollParentRef}
        >
            {items}
        </InfiniteScroll>
    </div>
</div>
