我是一名 GIS 分析师，被调到分析师程序员职位。这对我来说是一个艰难的过渡，因为我没有太多的编程背景，但我被投入其中。
我正在开发一个jsp 页面内的Flex 应用程序。本质上，它是一个包含图像和文本的 3x2 网格。我要做的是在此页面中有多个 titleWindow 引用，以便在单击图像时打开一个 titleWindow。（如果有人有更好的想法，特别是如果它与悬停有关，我对此非常开放！）目前我正在为一张图像工作。但是，当我尝试添加第二个功能时，它会出错。“错误 1021：重复的函数定义” 下面是调用 titleWindow 的主页的完整代码。下面的代码给出了错误 1021。

下面是titleWindow代码。到目前为止，此代码有效！

<mx:Script>
<![CDATA[
import mx.managers.PopUpManager;
import mx.controls.Text;
// A reference to the TextInput control in which to put the result.
public var loginName:Text;
// Event handler for the OK button.
private function returnName():void {
//loginName.text="Name entered: " + userName.text;
PopUpManager.removePopUp(this);
}

问题：我需要在上面更改哪些代码才能添加多个 titleWindow（最多 6 个），或者我可以使用哪些代码进行悬停以打开“窗口”或工具提示？
如果有人有任何想法或可以指导我，那就太好了。我很感激！
