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());
