反应虚拟化检测列表底部的滚动

如何解决反应虚拟化检测列表底部的滚动

我试图找出 List 组件何时在滚动时到达底部。滚动事件在开始时仅触发一次，之后它再也不会调用。如何检测滚动到达列表底部或最后一项。

const onScroll = (event) => {
        console.log(event);
        console.log("called");
    }

    return (
        <Box className={classes.root}>

            {((products && products.length > 0) || loadingProducts) && (
                
                <LzCard
                    onscroll={onScroll}
                    style={{height: '100%'}}
                    showShadow={false}
                    loading={loadingProducts}                    
                >
                    <Box classes={classes.scrollBox}>
                        
                        <InfiniteLoader
                            isRowLoaded={({ index }) => {
                                return !!products[index];
                            }}
                            loadMoreRows={({ startIndex,stopIndex }) => {
                                return Promise.resolve();
                            }}
                            rowCount={100000}
                            threshold={15}
                        >
                            {({ onRowsRendered,registerChild }) => (
                                <AutoSizer disableHeight>
                                    {({ width }) => (
                                        <div>
                                            <List
                                                onScroll={onScroll}
                                                ref={registerChild}
                                                rowCount={products.length}
