我有一个 SCORM 1.2 内容包，其中包含一些包含测验问题的 HTML 页面。单击提交按钮后，javascript 计算分数并返回。我当前的 java 脚本可以很好地解决两个问题，如果我在一页中有更多问题，那么我必须通过包含一个新变量来修改 javascript。我想知道是否有任何通用方法可以为“n”个问题编写相同的 javascript；无论问题数量如何变化，它都可以计算分数。感谢您。

我的 Java 脚本：（calculate.js）

您可以在函数调用时传递问题计数值

<form name="quizForm8" id="quizForm8" action="javascript:calcScore2();">

到

<form name="quizForm8" id="quizForm8" action="javascript:calcScore2(5);"> //5 -> Argument for 5 questions

-

function calcScore2(n)
{ 
    numQuestions = n;
