效果

支持响应式虚拟列表

在 react 中使用

npm i @hm-waterfall/react

import Watefall from "@hm-waterfall/react";

function App() {
  const listRef = useRef<HTMLDivElement>(null);
  const [columnNum, setColumnNum] = useState(2);
  const getData = (page: number, pageSize: number) => {
    return new Promise((resolve) => {
      fetch(`http://localhost:5000/getwaterfall?page=${page}&pageSize=${pageSize}`)
        .then((response) => response.json())
        .then((data) => resolve(data.data));
    });
  };
  return (
    <div className="root">
      <div className="list" ref={listRef}>
        <Watefall
          request={getData}
          columnNum={columnNum}
        />
      </div>
    </div>
  );
}
</div>;

增加卡片自定义底部信息

添加子组件,子组件接收一个当前卡片信息 item 参数,返回一个 ReactElement

<Watefall request={getData} columnNum={columnNum} onCardClick={cardClick}>
  {(item: IRenderItem) => (
    <div className="text-info">
      <div className="text">{item.title}</div>
      <div className="info">
        <img src={item.avatar} style={{ width: "20px", height: "20px", borderRadius: "50%" }} />
        <span>{item.author}</span>
      </div>
    </div>
  )}
</Watefall>

卡片点击事件 onCardClick

点击卡片事件函数,接收一个当前卡片信息 item 参数

function cardClick(item: IRenderItem) {
  alert(`点击了========${item.title}`);
}
<Watefall request={getData} columnNum={columnNum} onCardClick={cardClick} />;

自定义回到顶部和加载数据 loadingSlot backTopSlot

backTopSlot 函数返回自定义 ReactElement loadingSlot 函数返回自定义 ReactElement

const loadingSlot = <div className="loading">...</div>;
const backTopSlot = <div className="back-top-btn">↑</div>;

<Watefall
  request={getData}
  columnNum={columnNum}
  onCardClick={cardClick}
  loadingSlot={loadingSlot}
  backTopSlot={backTopSlot}
/>;
