java script random array shufler

[001921]

hi I'm just new to java and I'm trying to write a script that will shuffle the information in a array with no gaps and no repeats. below is that code that i have so far. thanks ben
[CODE]
//constants
SWAPS_TO_BE_MADE = 30;
//variables
var myArray = new Array('Ace',2,3,4,5,6,7,8,9,10,'Jack','Queen','King'); // the array that entities will be shuffled from
var temp = 0;
var outPutArray = new Array (12);
var arrayLength = myArray.length;
var index = 0;
var swapIndex = 0;
var self_swaps = 0;
var counter = 0;

temp=myArray[swapIndex]

document.write('<h1>Array shuffling</h1>');
document.write('<p>Before shuffle: '+myArray+'</p>');

//loop
while(counter < SWAPS_TO_BE_MADE) {
index =Math.floor(Math.random()*arrayLength);
swapIndex =Math.floor(Math.random()*arrayLength);
var index_value = index;
var range = 1;
myArray.splice(index_value,range,'spilced');
outPutArray[swapIndex] = index;


if(index == swapIndex) {
self_swaps++;
}
counter++;
index = (index + 1 % arrayLength);
swapIndex= (swapIndex + 1 % arrayLength);
}

document.write('<p>After shuffle: '+outPutArray+'</p>');
document.write('<p>After shuffle: '+myArray+'</p>');

There's easier ways to shuffle an array
var myArray = ['Ace',2,3,4,5,6,7,8,9,10,'Jack','Queen','King'];

Array.prototype.shuffle= function(){
	return this.sort(function(){
		return 0.5 - Math.random();
	})
}

alert(myArray.shuffle())

Array.prototype.disorder= function(){
	var i, temp, L= this.length, A= this.concat();
	while(--L){
		i= Math.floor(Math.random()*L);
		temp= A[i];
		A[i]= A[L];
		A[L]= temp;
	}
	return A;
}

alert(myArray.disorder());

thanks a lot that works much better thanks

Or rather shorter:-

<script type = "text/javascript">
var imgArray = new Array('Ace',2,3,4,5,6,7,8,9,10,'Jack','Queen','King'); 
function randOrd(){return (Math.round(Math.random())-0.5); }
imgArray.sort(randOrd);
alert (imgArray);
<script>

I'm just new to java

Java and Javascript are entirely different programming languages, in spite of the confusingly similar names.
