javaScript高手们，看看这段代码？我晕了

this.question=Question.arguments[0]＝＝》this.Question=Question.arguments[0]
试试

解决方案 »

  1.   

    程序可以运行：
    <script language="JavaScript">
    <!--
    //defining question object
    function Question(){
       this.question = Question.arguments[0];
       var n = Question.arguments.length;
       this.answers = new Array(n-2);
       
       for(var i=1;i<n-1;i++)
         this.answers[i-1] = Question.arguments[i];//   this.correctAnswer = Question.arguments[n-1];}qa = new Array();
    qa[0]=new Question("Who is the first president of the United States?",
                                                                      "George Washington",
                                       "Abraham Lincoln",
                                       "Benjamha Franklin",
                                       "Harry Truman",
                                       0);
    qa[1]=new Question("When did Columbus discover America",
                                                                       "1249",
                                       "1942",
                                       "1492",
                                       "1294",
                                       2);
    qa[2]=new Question("HongKong has returned to china for 5 years?",
                                                                       "True",
                                       "False",
                                       1);
    document.write(qa[0].question + " " + qa[0].answers[0] + " " + qa[0].answers[1] + " " + qa[0].answers[2] + " " + qa[0].answers[3] + " " + qa[0].correctAnswer);
    //-->
    </script>
      

  2.   

    可以运行的啊！（把两个文件放在同一目录下）
    test.htm<body>
    <script language="JavaScript">
    <!--
    //defining question object
    function Question(){
       this.question = Question.arguments[0];
       var n = Question.arguments.length;
       this.answers = new Array(n-2);
       
       for(var i=1; i<n-1; i++)
         this.answers[i-1] = Question.arguments[i];//这里我改了的，加了i   this.correctAnswer = Question.arguments[n-1];}
    //-->
    </script>
    <script language="JavaScript" src="test.js"></script>
    </body>
    ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
    test.js
    qa = new Array();
    qa[0]=new Question("Who is the first president of the United States?",
                                                                      "George Washington",
                                       "Abraham Lincoln",
                                       "Benjamha Franklin",
                                       "Harry Truman",
                                       0);
    qa[1]=new Question("When did Columbus discover America",
                                                                       "1249",
                                       "1942",
                                       "1492",
                                       "1294",
                                       2);
    qa[2]=new Question("HongKong has returned to china for 5 years?",
                                                                       "True",
                                       "False",
                                       1);
    document.write(qa[0].question + " " + qa[0].answers[0] + " " + qa[0].answers[1] + " " + qa[0].answers[2] + " " + qa[0].answers[3] + " " + qa[0].correctAnswer);

    思客，您好。我发现问题了，
    原先我把Question对象的定义放在head部分就老出现对象未定义的错误，像你那样放在body中就没有错了。能说明一下原因吗？
