1、设计思路 （1）子窗口调用父窗口的方法 （2）子窗口做了修改后，返回父窗口，父窗口调用子窗口函数 2、设计源码 （1）父窗口 ParentWindow.mxml： 复制代码 代码如下: <?xml version=\”1.0\” encoding=\”utf-8\”?> <s:Application xmlns:fx=\”http://ns.adobe.com/mxml/2009\” xmlns:s=\”library://ns.adobe.com/flex/spark\” xmlns:mx=\”library://ns.adobe.com/flex/mx\” width=\”100%\” height=\”100%\”> <s:layout> <s:BasicLayout/> </s:layout> <fx:Declarations> <!– 将非可视元素（例如服务、值对象）放在此处 –> </fx:Declarations> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; import mx.controls.Alert; import mx.managers.PopUpManager; [Bindable] //表格数据源绑定 private var grid:ArrayCollection = new ArrayCollection([ {number:\”2014010101\”,name:\”张散\”,sex:\”男\”,age:\”23\”}, {number:\”2014010102\”,name:\”李思\”,sex:\”女\”,age:\”22\”}, {number:\”2014010101\”,name:\”吴王\”,sex:\”男\”,age:\”21\”}, {number:\”2014010101\”,name:\”赵柳\”,sex:\”女\”,age:\”20\”}, {number:\”2014010101\”,name:\”游华\”,sex:\”男\”,age:\”22\”}, {number:\”2014010101\”,name:\”祝思\”,sex:\”女\”,age:\”18\”}, {number:\”2014010101\”,name:\”周礼\”,sex:\”男\”,age:\”19\”}, {number:\”2014010101\”,name:\”华捷\”,sex:\”女\”,age:\”20\”}, {number:\”2014010101\”,name:\”刘亮\”,sex:\”男\”,age:\”22\”}, {number:\”2014010101\”,name:\”沈雪\”,sex:\”女\”,age:\”21\”} ]); /*修改事件函数*/ protected function updateHandler(event:MouseEvent):void { //新建子窗体对象 var childWindow:ChildWindow = new ChildWindow(); //将子窗体添加到PopUpManager中 PopUpManager.addPopUp(childWindow,this,true); //向子窗体传递参数 childWindow.age = \”23\”; //子窗口调用父窗口函数 childWindow.callBack = this.myFunction; //子窗体居中弹出 PopUpManager.centerPopUp(childWindow); } /*刷新函数*/ public function myFunction(you:String):void { Alert.show(you+\”Hello\”); } ]]> </fx:Script> <mx:VBox width=\”100%\” height=\”100%\” paddingBottom=\”10\” paddingLeft=\”10\” paddingRight=\”10\” paddingTop=\”10\”> <mx:DataGrid id=\”dataGrid\” dataProvider=\”{grid}\” rowCount=\”{grid.length + 1}\” width=\”100%\” verticalAlign=\”middle\” textAlign=\”center\”> <mx:columns> <mx:DataGridColumn headerText=\”学号\” dataField=\”number\”/> <mx:DataGridColumn headerText=\”姓名\” dataField=\”name\”/> <mx:DataGridColumn headerText=\”性别\” dataField=\”sex\”/> <mx:DataGridColumn headerText=\”年龄\” dataField=\”age\”/> </mx:columns> </mx:DataGrid> <mx:HBox width=\”100%\” horizontalAlign=\”center\” verticalAlign=\”middle\”> <s:Button label=\”修改\” click=\”updateHandler(event)\”/> </mx:HBox> </mx:VBox> </s:Application> （2）子窗口 ChildWindow.mxml： 复制代码 代码如下: <?xml version=\”1.0\” encoding=\”utf-8\”?> <s:TitleWindow xmlns:fx=\”http://ns.adobe.com/mxml/2009\” xmlns:s=\”library://ns.adobe.com/flex/spark\” xmlns:mx=\”library://ns.adobe.com/flex/mx\” width=\”300\” height=\”220\” close=\”closeHandler(event)\” title=\”修改窗口\”> <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[ import mx.events.CloseEvent; import mx.managers.PopUpManager; //回调函数 public var callBack:Function; public var age:String = \”\”; /*关闭事件函数*/ protected function closeHandler(event:CloseEvent):void { PopUpManager.removePopUp(this); } /*修改按钮事件函数*/ protected function updateHandler(event:MouseEvent):void { stuAge.text = age; } /*取消按钮事件函数*/ protected function cancelHandler(event:MouseEvent):void { number.text = \”\”; stuName.text = \”\”; PopUpManager.removePopUp(this); if(isPopUp) { callBack.call(parent); } } ]]> </fx:Script> <fx:Declarations> <!– 将非可视元素（例如服务、值对象）放在此处 –> </fx:Declarations> <mx:VBox width=\”100%\” height=\”100%\”> <mx:Form> <mx:FormItem label=\”学号：\”> <s:TextInput id=\”number\” width=\”200\” maxChars=\”10\”/> </mx:FormItem> <mx:FormItem label=\”姓名：\”> <s:TextInput id=\”stuName\” width=\”200\” maxChars=\”10\”/> </mx:FormItem> <mx:FormItem label=\”性别：\”> <mx:HBox width=\”100%\”> <mx:RadioButtonGroup id=\”sex\”/> <s:RadioButton groupName=\”sex\” label=\”男\” selected=\”true\”/> <s:RadioButton groupName=\”sex\” label=\”女\”/> </mx:HBox> </mx:FormItem> <mx:FormItem label=\”年龄：\”> <s:TextInput id=\”stuAge\” width=\”200\” maxChars=\”2\”/> </mx:FormItem> <mx:FormItem> <mx:HBox width=\”100%\”> <s:Button label=\”修改\” click=\”updateHandler(event)\”/> <s:Label width=\”42\”/> <s:Button label=\”取消\” click=\”cancelHandler(event)\”/> </mx:HBox> </mx:FormItem> </mx:Form> </mx:VBox> </s:TitleWindow> 3、设计结果 （1）初始化时 
（2）单击修改按钮
