我一直在尝试使用 JavaScript 开发井字游戏。在我的过程中，我卡在了 addEventListener 部分。我得到:
Uncaught TypeError: action.addEventListener is not a function
错误。我该如何解决这个问题？

body{
background: url("img/wooden.jpg");
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);
}));
最佳答案
您应该将一个函数传递给 forEach 方法:
使用箭头函数:
action.forEach(action => action.addEventListener("click", (e) => {
console.log(e);
}));
