Question

我一直在尝试使用JavaScript玩井字游戏。在我的过程中，我陷入了addEventListener部分。我得到了：

未捕获的TypeError：action.addEventListener不是函数

错误。如何解决此问题？

    margin: 0;
    padding: 0;

#grid{
    font-size: 0;
    width: 800px;
    margin: 0 auto;
}

#grid div{
    margin: 2px;
    border: 4px solid transparent;
    display: inline-block;
}

#grid div:hover{
    opacity: 0.5;
}

const action = document.querySelectorAll("#grid");

action.forEach(action.addEventListener("click", (e) => {
    console.log(e);
}));

您应该将函数传递给forEach方法：

使用箭头功能：

action.forEach(action => action.addEventListener("click", (e) => {
    console.log(e);
}));

如何在JavaScript中修复“未捕获的TypeError：action.addEventListener不是函数”
