how to tackle a multi group quiz (logical approach)

Copy linkTweet thisAlerts:

Firstly thanks to all who help me get my code updated, very happy with it.

My current quiz has no correct answers scaled from 1-5 and each radio button has a individual point.
it totals and on result prints text value saying how well you did.

If questions were split in to groups eg Red questions Blue etc, what would be a logical approach to tackling it. So that 5 questions of each group are intermingled (20total) and on submit each groups score is printed out and and appropiate text response, eg well done.

Your blue scotre was: 40% well done
your Red score was 70% extremely knowledgeable

etc

Im sure that i have the tool already from the previous quiz so it just the best way about doing it.

I have thought if seperate forms four questions in each 5 times =20 questions?

@konithomimoOct 12.2006 — For example:
<html>
<head>
<script type="text/javascript">
var answers= new Array(1,3,0,4,2);

var blue=0
var red=0;

var numblues = 2;
var numreds = 3;

function scoreIt()
{
for(i=0;i<5;i++)
{
myquestion = eval("document.myform.q"+i);
for(j=0;j<myquestion.length;j++)
{
if(myquestion[j].checked)
{
if (j==answers[i])
{
if(myquestion[j].className=='blue')
blue++;
else
red++;
}
}
}
}
alert("Reds: "+ (((red/numreds).toFixed(2))*100) + "%");
alert("Blues: "+ (((blue/numblues).toFixed(2))*100) + "%");

}

</script>
</head>
<body>
<form name="myform">

@JMRKEROct 13.2006 — Suggestion:

I would put:
[code=php]
 var blue=0
var red=0;
var numblues = 2;
var numreds = 3;
function scoreIt() {
[/code]
like this:
[code=php]
function scoreIt() {
var blue=0
var red=0;
var numblues = 2;
var numreds = 3;
[/code]
to assure the score is reset to zero at the start of the function

rather than summarized with multiple 'scoreIt()' requests.

Good point. It should be written like that, or like this (since only the variables blue and red need to be reset to 0):
var numblues = 2;
var numreds = 3;
function scoreIt() {
var blue=0
var red=0;

Success!
