合并多个数组

合并多个数组,可合并一维数组和二维数组,哈哈.比较简单,自己先存着,以免以后用来
如:
var a1:Array=[1,2,3,4]
var a2:Array=[432,4,5,7]
var a3:Array=[36]
var aa:Array=[a1,a2,a3]


var m:mergeArray=new mergeArray;

//var a:Array=m.Merge(aa);//-----------1
var a:Array=m.Merge(a1,a2,a3)//--------2

trace(a + " = " + a.length);
//1,2都输入1,2,3,4,432,4,5,7,36 = 9

升级版-------------------------------------------不知还有没有更好的办法?
