对于deal（）函数，每次为curtain1输入1时，它都能正常工作，但每次为curtain2输入2时，它只会说“你想再玩一次，是或否？”但是，它不在代码的第2部分。

答案 0 :(得分：0)
让感觉发光
将大括号{ ... }放在多行if语句中
如果您没有放置它们，您的代码将只执行if
else if (won != "ZONK")
{
alert("YOU JUST WON " + won + " CONGRATULATIONS")
// the rest of your code if won != "Zonk"
因为在这种情况下，无论值var dealOver = prompt("DO YOU WANT TO PLAY AGAIN? YES OR NO").toUpperCase()是什么，都会执行curtainSelect，因为此说明不是if语句的一部分：if (curtainSelect == 1)
