Random selection for quiz script???

[booyahboy]

Hey Everyone!

I am trying to adapt the script found at the following page:

http://www.javascriptkit.com/script/...omboquiz.shtml

I am trying to find a modification to where instead of having the questions appear in numbered order, to generate in a random order?

Any input would be appreciated!

You can easily alter the popsolution.js file as follows:-

var total=5
var question=new Array()
for (i=1;i<=total+1;i++){
j = parseInt(Math.random() * total+1);  // 1-5
temp="choice"+j+"=new Array()"
eval(temp);
}

But of course this means that the same question may be repeated.

If you want to allow each question to appear only once you need to keep a record of which questions have already been selected.

You might try adapting something like this:

function Qwiz(){
	var q= [
	['2', 'Any fool can make a rule, and any fool will mind it.'],
	['5', 'Always forgive your enemies, nothing annoys them so much.'],
	['4', 'An ignorant person is one who doesn\'t know what you have just found out.'],
	['3', 'Beware of the young doctor and the old barber.'],
	['1', 'Better to remain silent and be thought a fool than to speak out and remove all doubt.']
	]
	this.questions= q.sort(function(a,b){return Math.random()- .5});
	this.selectfrom= '1. Abraham Lincoln,2. Henry David Thoreau,3. Benjamin Franklin,4. Will Rogers,5. Oscar Wilde';
}
Qwiz.prototype.next= function(){
	var score= 0, temp= '';
	while(this.questions.length){
	
		var tem= this.questions.shift();
		var A= this.selectfrom.split(',');
		var i= A.length;
		var q= tem[1];
		var a= tem[0];
		var s= A.join('\n');
		var s2= '\n'+q+'\n\nWho said it? Pick a number.\n\n'+s;
		var el= prompt(temp+s2)
		if(el.charAt(0)!== a.charAt(0)){
			var el= prompt('Try again?\n'+s2);
			if(!el || el.charAt(0)!= a.charAt(0)){
				i= 0;
			}
		}
		if(el.charAt(0)== a.charAt(0)){
			score+= i;
			temp= ('That is correct! '+score + 'points\n' );
		}
		else temp= 'Sorry. Wrong answer.\n';
	}
	var final= score>20? (score==25? 'Perfect!\n': 'Excellent!\n'): 'Final score: ';
	alert(final +score +' Points')
}

var Quiz= new Qwiz();
Quiz.next()
