随机数,想求不重复,输出随机范围所有数字

public function Main():void {          var arr:Array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];  var ranArr:Array = [];  var k:int;  var b:Boolean = true;  while (b) { k =  Math.random() * (arr.length); if (ranArr.indexOf(arr[k]) == -1) {trace("插入" + arr[k])ranArr.push(arr[k]); } if (ranArr.length == 10) {   b = false;  }  }  trace(ranArr.length);  for (var i:int = 0; i < ranArr.length; i++ ) {trace(ranArr[i]);    }  }

  while(b){     i = Math.random() * cardArr.length;     cardArr.push(cardArr.splice(i,1)[0]);     count++; if(count==500)  b= false;   }
