求居中呀

I modified my source code, but I still can't write test cases well. ```typescript // src/useInfiniteScroll.ts import { useRef } from "react"; import useEvent from "./useEvent"; import useCreateHandlerSetter from "./factory/createHandlerSetter";...

方案一的实现[demo](https://codesandbox.io/s/manual-image-lazy-6zzhr?file=/index.html)，ScrollListener类用于监听和处理滚动，在Controller（实现onEnterViewport方法）元素出现在视窗内时调用controller.onEnterViewport()，最后移除controller。 ```html offsetTop计算实现图片懒加载 body { margin: 0; } .img { width: 100%; height: 100%; object-fit: cover; object-position: center; } .wrap { margin: 10px; display: inline-block; width: 480px; height: 270px; }...
