我在 codepen 上试了一下你的代码。虽然你的问题是有点含糊，但我怀疑您遇到的问题是您正在做的事情：

buttonStart = addEventListener("click", startGame); buttonReset = addEventListener("click", startAgain);

而不是

buttonStart.addEventListener("click", startGame); buttonReset.addEventListener("click", startAgain);

说明：您应该将事件侦听器应用于 buttonStart 和 buttonReset，而不是等同于它们。
