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

package
{
	
	/**
	 * ...合并多个数组,可合并一维数组和二维数组
	 * @author zkl
	 */
	public class mergeArray
	{
		private var i:int;
		
		private var j:int;
		
		public function Merge(...args):Array
		{
			var _newArray:Array = new Array;
			
			var len:int = args.length;
			
			if (len == 1) {
				
				//二维数组
				if (args[0] is Array) {
					
					for (i = 0; i < args[0].length; i++ ) {
						//合并一维数组
						 _newArray = mergeing(args[0]); 
						 
					}
				}
				
			}else {
				
				_newArray = mergeing(args);
				
			}
				
			return _newArray;
			
		}
		
		/**
		 * 合并一维数组
		 */
		private function mergeing(a1:Array):Array
		{
			var a:Array = new Array;
			
			for (i = 0; i < a1.length; i++ ) {
					
					if (a1[i] is Array) {
						
					    for (j = 0; j < a1[i].length; j++ ) {
						 
					    	a.push(a1[i][j]);
						 
					    }
						
					}
				}
		    
			return a;
		}
		
	}
	
}

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

package {

	/**
	 * ...合并多个数组,可合并一维数组和二维数组
	 * @author zkl

	 */
	public class mergeArrayOk {
		public function Merge(... args):Array {
			return merge1(args);
		}

		private function merge1(arr:Array):Array {
			var i:int, j:int;
			var _tempArray:Array = new Array;
			//为了不让每次循环都计算数组长度
			var len:int = arr.length;
			for (i = 0; i < len; i++){
				if (arr[i] is Array){
					var len2:int = arr[i].length;
					for (j = 0; j < len2; j++){
						if (arr[i][j] != null){
							_tempArray.push(arr[i][j]);
						}
					}
				} else if (arr[i] != null){
					_tempArray.push(arr[i]);
				}
			}
			//查询_tempArray是否还有数组,有则再次转换
			var m:int;
			var len3:int = _tempArray.length;
			for (i = 0; i < len3; i++){
				if (_tempArray[i] is Array){
					return merge1(_tempArray);
					break;
				} else {
					m++;
					if (m == _tempArray.length){
						return _tempArray;
					}
				}
			}
		}
	}
