推荐答案

或者，您可以手动触发实际的 scroll 事件，如下所示:

Alternatively, you can manually trigger a real scroll event as following:

el.dispatchEvent(new CustomEvent('scroll'))

与通过 +1 和 -1 像素进行双滚动的感觉相比，感觉更少的黑客攻击(而且性能更高)...

Which feels a bit less of a hack (and more performant) than dual scrolling by +1 and -1 pixels...

这应该运行任何侦听 scroll 事件的代码.

This should run any piece of code listening for a scroll event.

要支持 IE11 或其他旧版浏览器，请考虑使用 CustomEvent polyfill，例如 mdn-polyfills

To support IE11 or other legacy browser, consider using a CustomEvent polyfill such as mdn-polyfills
