React Infinite Scroller

⚠️⚠️ 必读

该 Fork 主要是处理在高版本 Chrome 上，flex-direction: column-reverse会使父级组件的scrollTop变成负数，基于此，主要对isReverse开启的时候，进行了比较粗暴的处理，以保证滚动页面的计算不会出错。

以上，该项目主要用于 WorkPlusFE 内部。

# npm
npm install @w6s/react-infinite-scroller --save

# yarn
yarn add @w6s/react-infinite-scroller

Installation

yarn add react-infinite-scroller

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>
