Asleep at the actionscript

hi guys here I have given you the function to make an array random….

function randomArray(Arr:Array):Array {
var dummy:Array=new Array();
var dummy2:Array=new Array();
for (var i=0; i<Arr.length; i++) {
var d:int=Math.round(Math.random()*(Arr.length-1));
while  (dummy.indexOf(d)!=-1) {
d=Math.round(Math.random()*(Arr.length-1));
}
dummy.push(d);
}
for (var j=0; j<dummy.length; j++) {
dummy2.push(Arr[dummy[j]]);
}
return dummy2;
}

var  Arr:Array=new Array("1","2","3","4","5","6","7","8");
trace(randomArray(Arr));

Is there any simple idea, please given that is appreciated…
