抱歉，标题不好，我不知道如何正确表达它

这是我正在尝试构建的 Tic Tac Toe 游戏 -

我试图在reset()内部调用set()，以便每次单击#reset按钮时，下次单击容器时都会显示“X”。

现在，它适用于前两次单击，当我将函数传递到 HTML 按钮标记时，它会运行三次，但下一次单击会显示“O”。我每次都需要它工作，因为当你重置游戏时，应该是“玩家 1 的回合”，它在容器上显示“X”

#heads {

    text-align: center;
    font-size: 30px;

#container {

感谢您的帮助!

最佳答案

问题出在 set 函数本身。当您不断调用 set 函数时，它会不断向容器添加多个事件监听器。因此，当您单击该框时，单击一次就会触发多个事件。相反，附加一个事件监听器一次，然后在重置时设置正确的数据属性，如下面的代码片段所示

#heads {
    padding-top: 30px;
    text-align: center;
    font-size: 30px;
    color: rgb(46, 46, 46);
}

#container {
    text-align: center;
    margin-top: 20px;
    display: grid;
    grid-template-columns: 1fr 1fr 1fr;
    grid-template-rows: 1fr 1fr 1fr;
    width: 300px;
    height: 300px;
    background-color: rgb(46, 46, 46);
    border: 1px solid  rgb(255, 255, 255);
}

#container div {
    font-size: 25px;
    border: 2px solid rgb(255, 255, 255);
    color: white;
    text-align: center;
    padding-top: 35px;
}

#container div:hover {
    background-color:rgb(58, 58, 58);
}

#reset {
    margin-top: 10px;
    background-color: rgb(46, 46, 46);
    color: white;
    border-radius: 3px;
    outline: none;
}

#reset:hover {
   background-color:  rgb(58, 58, 58);
}

#divone {
    font-size: 18px;
    margin-top: 15px;
    color: rgb(46, 46, 46);
}

#divtwo {
    display: none;
    font-size: 18px;
    margin-top: 15px;
    color: rgb(46, 46, 46);
}
