@annaunivrajanAug 18.2010 — #Hi John,

Due to some urgent work i could not complete the code. But this will give an idea how to do...

<html>

<head>

<script language="javascript">

var arr=new Array(5);

var randArray=new Array();

arr[1]="Sonia";

arr[2]="Manmohan";

arr[3]="Vajpayee";

arr[4]="Rahul";

var counter=-1

</script>

<script>

function ShowRandomAnswers()

{

// alert('Hi');

getRandomNumber();

 /*alert(randArray[0]);
   alert(randArray[1]);
   alert(randArray[2]);
   alert(randArray[3]);*/

pos1=randArray[0];

pos2=randArray[1];

pos3=randArray[2];

pos4=randArray[3];

document.getElementById('a1').innerHTML=arr[pos1];
  document.getElementById('a2').innerHTML=arr[pos2];
  document.getElementById('a3').innerHTML=arr[pos3];
  document.getElementById('a4').innerHTML=arr[pos4];

}

function getRandomNumber()

{

var rand_no = Math.random();

rand_no = rand_no * 4;

var res = Math.ceil(rand_no);

//alert(res);

//alert(isUnique(res));

if(isUnique(res)!="true")

{

if(randArray.length<4)

{

getRandomNumber();

}

}

else

return res;

}

function isUnique(r)

{

var flag=true;
  if(randArray.length==0)
   { 
   counter=counter+1;
  randArray[counter]=r;
 
   return flag;
  }
  for(var j=0;j<randArray.length;j++)
  {
   if(randArray[j]==r){flag=false;break;}
 
  }
  if(flag==true)
  {
   counter=counter+1;
   randArray[counter]=r;
   return flag;
  }

// alert("Array Length : "+randArray.length+"Array Item :"+randArray[counter]);

return false;

}

</script>

</head>

<body onload="ShowRandomAnswers()">

<p> Who is the PM of India ? </p>

<input type="radio" /><button id="a1"/><br />

<input type="radio" /><button id="a2"/><br />

<input type="radio" /><button id="a3"/><br />

<input type="radio" /><button id="a4"/><br />

</body>

</html>

As of now i have shown the data in button. You can put label or font or p tag and set the value dynamically....

Cheers,

P. Rajan

@tirnaAug 18.2010 — #Since the OP put their post in the PHP forum and not the Javascript forum I suspect the OP is looking for a server side solution and not a client side one - especialy since the questions and choices are stored in a database.

If it was me building the application, I would do it all server side as it would be less work because I wouldn't have to transfer all the data in the database to javascript variables.
