我没有得到我正在寻找的答案。 我想将请求数据发送到主应用程序。

答案 0 :(得分：0)
我建议您通过添加自定义事件来解决此问题，因为您的标记暗示您可能会理解。
如果没有，请遵循以下步骤。
1）创建一个新的Event类型（在actionscript中扩展Event类 - 一定要覆盖clone（））
2）在弹出窗口
上的父应用程序中为新的事件类型添加一个事件监听器3）使弹出窗口在关闭之前调度新的事件类型
4）在事件处理程序中处理你正在寻找的任何内容（userID？）。
我建议将userID附加到实际事件，以便父级不直接寻址login.userID。从松耦合的角度来看，它更正确。也就是说，如果您不希望，可以通过不附加userID来简化解决方案。松耦合是一个伟大的目标，但如果你只打算一次使用这种关系，那就不是非常必要了。
如果您选择更紧密的耦合路线，那么您只需要使用自定义“类型”而不是扩展事件来发送事件。
如果你需要一个较低级别的例子（较少的描述，更多的代码）让我知道，我也可以提供帮助。
下面提供的示例是稍微复杂的版本，您可以在其中扩展事件以包含数据。
事件类::
package mycomponents
{
import flash.events.Event;
public class CustomEvent extends Event
{
public static const EVENT_TYPE_NAME:String = "myEventType"
public var mUserID:String = "";
public var mSuccess:Boolean = false;
public function CustomEvent(aType:String, aUserID:String, aSuccess:Boolean)
{
super(aType)
mUserID = aUserID;
mSuccess = aSuccess;
}
override public function clone():Event
{
var lEvent:CustomEvent = new CustomEvent(mUserID, mSuccess);
return lEvent;
}
}
}
在Popup ::
中private var loginSuccessful:Boolean = false;
private function onDataLoaded(e:Event):void{
var xml:XML= new XML(e.target.data);
if(xml.status=="success"){
userID = username.text;
loginSuccessful = true;
//SEND DATA TO MAIN APPLICATION
dispatchEvent(new CustomEvent(CustomEvent.EVENT_TYPE_NAME, userID, loginSuccessful );
PopUpManager.removePopUp(this);
}else{
fail.visible=true;
username.text="";
password.text="";
username.setFocus();
}
}
protected function titlewindow1_removeHandler(event:FlexEvent):void
{
if (!loginSuccessful)
dispatchEvent(new CustomEvent(CustomEvent.EVENT_TYPE_NAME," userID, loginSuccessful ));
}
在Main Application ::
中import mycomponents.CustomEvent;
private function application1_creationCompleteHandler(event:FlexEvent):void
{
//...your code
login.addEventListener(CustomEvent.EVENT_TYPE_NAME, handleLoginEvent);
}
private function handleLoginEvent(aEvent:CustomEvent)
{
//My example code dispatches an event with mSuccess = false if the login prompt closes
//without a successful login
//
//now do whatever you want with the information from the popup
//aEvent.mUserID gets you ID
//aEvent.mSuccess gets you success
}
在工作休息期间一起抛弃，所以没有承诺会按原样编译。
