大家好,我目前正在开发一个简单的 Javascript 井字棋游戏。
到目前为止,除了一件事之外,一切都运行良好......
主函数中有一个 checkForWin()
函数,该函数检查每个可能的获胜组合,看看“X”或“O”是否获胜。
if checkForWin() === true thenalert('game over');
它会执行此操作,但不会在您做出获胜 Action 后立即发出警报,它只会在之后的“点击”时发出警报? ??
(问题 1) 所以说“X”是对 Angular 线排列的。 alert('game over')
在“O”点击其方 block 之前不会运行。另外,当“O”执行此操作时,将显示警报消息,然后字母“O”将被放置在正方形中???
任何帮助都是极好的!谢谢。
最佳答案
您过早调用 switchTurn()
。您的 checkForWin()
函数正在检查下一个playerTurn
字符(X
或 O
)。 玩家而不是刚刚移动的玩家。
您可以按如下方式重写 runGame()
函数:
function runGame() {
if(gameEnded || cell.innerHTML) {
return;
}
cell.innerHTML = playerTurn;
if(checkForWin()) {
alert('game over');
}
switchTurn();
}
