随机排序数组

var allNoGameFriends:Array = [1,2,3,4,5,6,7,8,9]
var list:Array = new Array();
var newArr:Array = new Array();
//产生0~i-1的不重复的i个随机数  
for (var i:int=0; i<allNoGameFriends.length; i++)
{
    list.push(i);
}
while (list.length>0)
{
    var index:int = Math.floor(Math.random() * list.length);
    newArr.push(allNoGameFriends[list[index]]);
    //选出一个之后去掉这个数 
    list.splice(index, 1);
}
allNoGameFriends = newArr.concat();

trace(allNoGameFriends)

 

function taxis(element1:*,element2:*):int
{
    trace(element1+","+element2)
    
    var num:Number = Math.random();
    if (num<0.5)
    {
        return -1;
    }
    else
    {
        return 1;
    }
}
var arr:Array = ["c","b","a","3","2","1"];
//trace("原来的数组:"+arr);
//输出:c,b,a,3,2,1;
arr.sort(taxis);
//trace("第一次排序:"+arr);
//随机排序后的数组arr ;
arr.sort(taxis);
//trace("第二次排序:"+arr);
//随机排序后的数组arr ;

arr.sort(taxis);
//trace("第三次排序:"+arr);
//随机排序后的数组arr ;
arr.sort();
//trace("按 Unicode 值排序:"+arr);//输出:1,2,3,a,b,c
