Javascript 数组中未被函数读取的属性-无法读取未定义的属性

我有点麻烦。我在BusinessCatalyst中工作，它存储动态用户提交的数据，并允许我以任何需要的方式输出数据

我已经创建了一系列网络应用程序，它们一起工作，允许用户参加测验。当前我收到一条错误消息“Uncaught TypeError:无法读取未定义的属性”questionText“

我的代码当前的工作方式：

用户提交带有测验/调查数据的表单

他们将被引导到一个新页面，该页面运行对其用户独有的最新测验/调查提交的搜索

数据在div内的页面上输出

函数读取数据并相应地构建页面内容，以显示正确的测验/调查结果

提交的数据以以下格式输出。请注意，{tags}是一种输出动态信息的方式，{tag}被替换为页面上用户提交的数据。还请注意，我只显示了3个问题的数据，总共有15个问题

var quizSurvey = "{tag_quiz/survey}";
    var w = window.innerWidth;
    function Question(questionNumber, questionText, answerType, answerA, answerB, answerC, answerD, correctAnswer, userMultichoice, userTF, userSRating, userSSAnswer, qPassFail) {
        this.questionNumber = questionNumber;
        this.questionText = questionText;
        this.answerType = answerType;
        this.answerA = answerA;
        this.answerB = answerB;
        this.answerC = answerC;
        this.answerD = answerD;
        this.correctAnswer = correctAnswer;
        this.userMultichoice = userMultichoice;
        this.userTF = userTF;
        this.userSRating = userSRating;
        this.userSSAnswer = userSSAnswer;
        this.qPassFail = qPassFail;
    };
    var question = new Array();
question[1] = new Question("1", "{tag_q1-question}", "{tag_q1-answer-type}", "{tag_q1-multichoice-a}", "{tag_q1-multichoice-b}", "{tag_q1-multichoice-c}", "{tag_q1-multichoice-d}", "{tag_q1-correct-answer}", "{tag_q-multichoice-1}", "{tag_q-t/f-1}", "{tag_s-ratings-1}", "{tag_s-shortanswer-1}", "{tag_q1-pass/fail}");
question[2] = new Question("2", "{tag_q2-question}", "{tag_q2-answer-type}", "{tag_q2-multichoice-a}", "{tag_q2-multichoice-b}", "{tag_q2-multichoice-c}", "{tag_q2-multichoice-d}", "{tag_q2-correct-answer}", "{tag_q-multichoice-2}", "{tag_q-t/f-2}", "{tag_s-ratings-2}", "{tag_s-shortanswer-2}", "{tag_q2-pass/fail}");
question[3] = new Question("3", "{tag_q3-question}", "{tag_q3-answer-type}", "{tag_q3-multichoice-a}", "{tag_q3-multichoice-b}", "{tag_q3-multichoice-c}", "{tag_q3-multichoice-d}", "{tag_q3-correct-answer}", "{tag_q-multichoice-3}", "{tag_q-t/f-3}", "{tag_s-ratings-3}", "{tag_s-shortanswer-3}", "{tag_q3-pass/fail}");
    var userScore = "{tag_total score}";
    var passingScore = "{tag_required score to pass}";
    var showAnswers = "{tag_show answers}";

现在您看到了数据是如何存储的，下面是输出数据的页面的代码。请注意，我遗漏了第2步，即运行搜索的代码-我知道这是可行的，所以我不认为您需要查看它

完成这一章做得很好

你的分数是：
你没有达到要求的及格分数。请复习材料并再次进行测验以完成本章。
感谢您完成调查。
您的答案已提交。
正确答案
虽然您通过了测验，但有一个或多个答案不正确。
以下是正确答案
var quizsurveyDiv=document.getElementById（'qs-results'）.innerHTML；
如果（quizsurveyDiv==“”）{
var元素=“{module_url，AllIDs}”；
var arrayOfStrings=element.split（“-”）；
document.getElementById（'CAT_Custom_206'）。value=ArrayOfString[0]；
document.getElementById（'CAT_Custom_2'）。value=ArrayOfString[1]；
document.getElementById（'CAT_Custom_3'）。value=ArrayOfString[2]；
catcustomcontentform9225.submit（）；
}否则{
如果（quizSurvey==“测验”）{
变量qNumber=0；
var qNumbers=函数（）{
对于（i=0；i没有人会调试几百行代码。请提供一个再现您的问题的最小示例。我已经尽可能地减少了。我可以在输出所有内容的地方删除div内容，但其余的信息是绝对需要的。如果我删除div内容，它将有94行代码-几乎没有几行红色。您的问题可能是
qNumbers
中的循环增加到14，但您只有3个问题？或者您的数组没有
0
索引值（您以
questions[1]=…
开始，但您的循环以
i=0
开始）？您在哪一行上看到错误？就是这样！谢谢您！！
