Question

I have 2 buttons ,when click on JFXButton 'inscrire', anchorPane Login bring to Front if click on Login anchorPane SignUp bring to Front

我的问题是NetBeans调用了一个异常，即#handleButtonAction方法控制器没有在根组件上定义。

Answer 1

看起来你没有控制器属性。您需要添加一个控制器属性，以便您的视图可以与其控制器进行交互。在关闭根元素的开始标记之前插入fx:controller="com.yourcompany.YourController"。

示例：<AnchorPane ... fx:controller="com.yourcompany.YourController">

接下来，在您的控制器类中，确保您具有如下设置的功能：

@FXML
void handleButtonAction(ActionEvent e) {
    // Your logic goes here...
}

现在，当您通过FXML加载视图时，它应该能够与控制器类进行交互。
