Flex深拷贝

通常我们需要深拷贝flex对象的时候 我们会google到这样的信息

		public function DeepClone( target : Object ) : *
		{
			var myBA:ByteArray = new ByteArray();  
			
			myBA.writeObject( target );  
			myBA.position = 0;  
			
			return( myBA.readObject() );  
		}

这个用来拷贝Array或者其他一些数据类的时候 我们发现他是OK的

但是如果要深拷贝DisplayObject的时候这个函数就会发生运行时错误

在网上发现这么一篇文章

直接跳到Answer5吧 看看怎么复制DisplayObject

		public function duplicateDisplayObject(
			source:DisplayObject,autoAdd:Boolean = false
		):DisplayObject
		{
			// create duplicate
			var sourceClass:Class = Object(source).constructor;
			var duplicate:DisplayObject = new sourceClass();
			
			// duplicate properties
			duplicate.transform = source.transform;
			duplicate.filters = source.filters;
			duplicate.cacheAsBitmap = source.cacheAsBitmap;
			duplicate.opaqueBackground = source.opaqueBackground;
			if (source.scale9Grid) {
				var rect:Rectangle = source.scale9Grid;
				// WAS Flash 9 bug where returned scale9Grid is 20x larger than assigned
				// rect.x /= 20,rect.y /= 20,rect.width /= 20,rect.height /= 20;
				duplicate.scale9Grid = rect;
			}
			
			// add to source parent's display list
			// if autoAdd was provided as true
			if (autoAdd && source.parent) {
				source.parent.addChild(duplicate);
			}
			return duplicate;
		} 

好了..搞定
