javascript - 如果答案不正确，如何让用户重新创建函数

Question

我想向用户提问。向左、向右或继续直行。如果用户在 javascript prompt 方法中写入“straight”。其他 2 种方法都是错误的 - 游戏结束。游戏什么时候结束我希望用户再次制作这个故事。

var prompt = propmt("Where will you go? Left, right or continue straight?");
if (prompt === "Left") {
  confirm("Game over, the tigers will eat you!");
} else if (where === "Straight") {
  confirm("You've won!");
} else {
  confirm("Game over, you've fallen to the river!");
}

如果游戏结束，我希望用户重试这个故事。谢谢!

像这样的东西会起作用:

function game() {
  while (true) {
    var prompt = prompt("Where will you go? Left, right or continue straight?");

    if (prompt === "Left") {
      confirm("Game over, the tigers will eat you!");
    } else if (prompt === "Straight") {
      confirm("You've won!");
      return
    } else {
      confirm("Game over, you've fallen to the river!");
    }
  }
}

这不是理想的执行方式(请注意 while(true))，但这将使您得到最终结果。

更好的方法:

function game() {
  var prompt = ""
  while (prompt != "Left" || prompt != "Straight") {
    prompt = prompt("Where will you go? Left, right or continue straight?");
    if (prompt === "Left") {
      confirm("Game over, the tigers will eat you!");
    } else if (prompt === "Straight") {
      confirm("You've won!");
    } else {
      confirm("Game over, you've fallen to the river! Let's play again!");
    }
  }
}
