Question

这里的问题是这样的：每次我运行这段代码时，它运行良好，但是当它出错时我没有执行while循环再次迭代游戏，我无法找到问题。

<!DOCTYPE html>

<head>
    <title>Color guessing game</title>
</head>

<body onload="do_game()">
    <script>
        var color = ["Black","Blue","Brown","Cyan","GoldenRod","Green","Maroon","Olive","Pink","Red"];
        var target;
        var finished = false;
        var guess_input;
        var guesses;

        function do_game() {
            var target_index = Math.random() * 10;
            var target = Math.floor(target_index);

            alert(color[target]);

            while(!finished) {
                guess_input = prompt("I am thinking of one of these colors: \n\n" +
                                        "Black,Blue,Brown,Cyan,GoldenRod,Green, Maroon,Olive,Pink,Red \n\n"
                                        + "What color am i thinking of?");
                guesses +=1;
                finished = check_guess();
                }
        }

        myBody.style.background=name_of_color;
    </script>

</body>

Answer 1

您从未定义过函数check_guess。

当浏览器尝试在该行上执行代码时，它发出错误并且脚本停止。

寻找＆＃34;开发人员工具＆＃34;或浏览器中的类似菜单项，您将看到其中显示的错误。

我的猜测也是您的脚本在变量myBody和name_of_color方面存在问题，这些变量也不会出现在您的脚本中。但是既然你说'＃34;它运作良好＆＃34;可能有些事情你没有向我们展示。

你的问题中缺少一些东西（我们不知道什么是check_guess ??），但我尝试做一些工作，让你非常接近你正在寻找的东西。希望这个解决方案可以帮到你。

var color = ["Black", "Blue", "Brown", "Cyan", "GoldenRod", "Green", "Maroon", "Olive", "Pink", "Red"];
var target;
var finished = false;
var guess_input;
var guesses;
var randomComputerGuess;

function do_game() {
  var target_index = Math.floor(Math.random() * 10);

  alert(color[target_index]);
  randomComputerGuess = color[target_index];

  while (!finished) {
    guess_input = prompt("I am thinking of one of these colors: \n\n" +
      "Black,Blue,Brown,Cyan,GoldenRod,Green, Maroon,Olive,Pink,Red \n\n" + "What color am i thinking of?");
    if (randomComputerGuess === guess_input) {
      alert("Good Job! You guessed it.");
      finished = true;
      //document.style.background=color[target_index];
    }
  }
}

<body onload="do_game()">

颜色猜谜游戏在错误时不会循环
