跟踪一系列简单的多项选择网络表单答案

Question

这是我正在尝试使用的代码，这似乎是合乎逻辑的。但似乎不起作用。

MyAsFileName.prototype.getTotalScore = function() {
 var totalScore = 0;
 for (var i = 0; i < allQuestions.length; i++) {
  totalScore += allQuestions[i].getCalculatedScore();
  if (currentModule.allQuestions[i].parent.questionCorrect == true) {
   knowledgePoints++;
  } else {
   knowledgePoints--;
  }
 }
 debugLog("Total score: " + totalScore);
 debugLog(knowledgePoints);
 return totalScore;
}

我将allQuestions 定义如下：

var allQuestions    = Array(); 

我将knowledgePoints 定义为：

 this.knowledgePoints = 10;

我将questionCorrect 定义为：

this.questionCorrect = false;

第二次新尝试使用新课程作为以下建议的答案（暂时注释掉，直到我弄清楚如何开始工作）：

// package
// {
/*public class Quiz {
 //public
 var knowledgePoints: int = 10;
 //public
 var allQuestions: Array = new Array;
 //public
 var questionCorrect: Boolean = false;

 //public
 function getTotalScore(): int {
  var totalScore: int = 0; 

  for (var i = 0; i < allQuestions.length; i++) {
   totalScore += allQuestions[i].getCalculatedScore();

   if (currentModule.allQuestions[i].parent.questionCorrect) {
    knowledgePoints++;
   } else {
    knowledgePoints--;
   }
  }
  debugLog("Total score: " + totalScore);
  debugLog(knowledgePoints);

  return totalScore;
 }
}*/
//}

上面这段代码在 flash 控制台中输出两个错误：

错误 1. 属性在类外使用。

错误 2。无法加载“Int”。

Answer 1

这是一种奇怪的（实际上是非 AS3 方式）方法。与其创建一个未命名的闭包，它从不知道在哪里引用奇怪的变量，不如让它成为一个普通的 AS3 类，类似这样的东西（在一个名为 Quiz.as 的文件中）：

package
{
    public class Quiz
    {
        public var knowledgePoints:int = 10;
        public var allQuestions:Array = new Array;
        public var questionCorrect:Boolean = false;

        public function getTotalScore():int
        {
            var totalScore:int = 0;

            // Your code does not explain how you will that Array.
            // It is initially an empty Array of length 0.
            for (var i = 0; i < allQuestions.length; i++)
            {
                totalScore += allQuestions[i].getCalculatedScore();

                if (currentModule.allQuestions[i].parent.questionCorrect)
                {
                    knowledgePoints++;
                }
                else
                {
                    knowledgePoints--;
                }
            }

            // Not sure what it is.
            debugLog("Total score: " + totalScore);
            debugLog(knowledgePoints);

            return totalScore;
        }
    }
}
