It's been a long time since I've done any coding. I think this is
pretty straightforward but it has me beat. Can you help?
I'm working on a quiz using AS1 (I think) that reads questions and
answers from an xml file. (see below for the script).
I'd like to introduce line breaks into the feedback, how do I do this?
I've tried using \r but it just displays this as text.
Ideally I'd like to display the text as html but so far my efforts to
do this have broken the script - any pointers?
Here's the action script for the quiz. I hope it makes sense:
function QuizItem(question)
{
this.question=question;
this.answers=new Array();
this.feedbacks=new Array();
this.numOfAnswers=0;
this.correctAnswer=0;
this.getQuestion=function()
{
return this.question;
}
this.addAnswer=function(answer, isCorrectAnswer, feedback)
{
this.answers[this.numOfAnswers]=answer;
this.feedbacks[this.numOfAnswers]=feedback;
if (isCorrectAnswer)
this.correctAnswer=this.numOfAnswers;
this.numOfAnswers++;
}
this.getAnswer=function(answerNumberToGet)
{
return this.answers[answerNumberToGet];
}
this.getFeedback=function(answerNumberToGet)
{
return this.feedbacks[answerNumberToGet];
}
this.getCorrectAnswerNumber=function()
{
return this.correctAnswer;
}
this.checkAnswerNumber=function(userAnswerNumber)
{
if (userAnswerNumber==this.getCorrectAnswerNumber()) {
numOfQuestionsAnsweredCorrectly++;
} else {
numOfQuestionsAnsweredIncorrectly++;
}
feedback = _root["feedback"+parseInt((userAnswerNumber+1))]
gotoAndPlay("Feedback");
}
}
function onQuizData(success)
{
var quizNode=this.firstChild;
var quizTitleNode=quizNode.firstChild;
title=quizTitleNode.firstChild.nodeValue;
var i=0;
// <items> follows <title>
var itemsNode=quizNode.childNodes[1];
while (itemsNode.childNodes[i])
{
var itemNode=itemsNode.childNodes[i];
// <item> consists of <question> and one or more <answer>
// <question> always comes before <answer>s (node 0 of <item>)
var questionNode=itemNode.childNodes[0];
quizItems[i]=new QuizItem(questionNode.firstChild.nodeValue);
var a=1;
// <answer> follows <question>
var answerNode=itemNode.childNodes[a++];
while (answerNode)
{
//trace(answerNode);
var isCorrectAnswer=false;
if (answerNode.attributes.correct=="y")
isCorrectAnswer=true;
//get answer
tempAnswer = answerNode.firstChild.nodeValue;
//go to next node
answerNode=itemNode.childNodes[a++];
//get feedback
tempFeedback = answerNode.firstChild.nodeValue;
//add answer and feedback to current answer/feedback
'pair'
quizItems[i].addAnswer(tempAnswer, isCorrectAnswer,
tempFeedback);
// goto the next <answer>
answerNode=itemNode.childNodes[a++];
}
i++;
}
gotoAndStop("Start");
}
var quizItems=new Array();
var myData=new XML();
myData.ignoreWhite=true;
myData.onLoad=onQuizData;
myData.load("google_quiz.xml");
stop();
And this is what the xml file looks like:
<!DOCTYPE quiz [
<!ELEMENT quiz (title, items)>
<!ELEMENT title (#PCDATA)>
<!ELEMENT items (item)+>
<!ELEMENT item (question, answer, answer+)>
<!ELEMENT question (#PCDATA)>
<!ELEMENT answer (#PCDATA)>
<!ELEMENT feedback (#PCDATA)>
<!ATTLIST answer correct (y) #IMPLIED>
]>
<quiz>
<title>My quiz</title>
<items>
<item>
<question>What colour are greenfly</question>
<answer>Red</answer>
<feedback>You chose answer [a]. This is incorrect. The correct
answer is [d].</feedback>
<answer>Blue</answer>
<feedback>You chose answer [b]. This is incorrect. The correct
answer is [d].</feedback>
<answer>Cheese</answer>
<feedback>Sorry, cheese is not a colour.</feedback>
<answer correct="y">Green</answer>
<feedback>Correct!</feedback>
</item>
</quiz>
Thanks for reading, any help would be very gratefully received.
