            {
                this.visible=false;
            }   
            protected function bordercontainer1_creationCompleteHandler(event:FlexEvent):void
            {

                var lujing:String="assets/"+ mytext +".mp4";                
                vd1.source=lujing;
            }

        ]]>
    
    
        
    
    "vd1" x="-1" y="-1" width="314" height="230" chromeColor="#9A9898"/>
    "286" y="-2" width="29" height="32" source="assets/关闭(1).png" buttonMode="true" click="image1_clickHandler(event)"/>

：
关键点

• 子窗口中添加变量public var mytext:String;
• 主窗体内将值传给mytext例如：tw.mytext=label1.text;
