推荐答案

您无需更改系统范围的设置，但仍会有250ms的延迟，您可以观看同一键的keydown和keyup事件(请不要忘记用户可以一次按下多个键，然后以不同的顺序释放它们).在按下按键时以所需的频率启动一个计时器，在按下按键时将其停止，然后将之前的按下按键处理程序设置为计时器处理程序.

Instead of changing the system-wide settings and still have a delay of 250ms, you can watch keydown and keyup events for the same key (don't forget that a user can press multiple keys at once and release them in different order). Start a timer with required frequency on keydown, and stop it on the keyup, and set your previous keydown handler as a timer handler.
