问题描述
我需要调用位于父组件中的函数，并在Flex 3中从子组件进行调用.是否可以通过子组件访问父组件中的函数?我知道我可以在孩子中调度一个事件，并在父对象中添加一个侦听器来调用该函数，但只是想知道是否也可以直接从孩子中调用父函数.谢谢
I need to call a function located in the parent component and make the call from the child component in Flex 3. Is there a way to access functions in the parent component from the child component? I know I can dispatch an event in the child and add a listener in the parent to call the function, but just wanted to know if could also directly call a parent function from a child. Thanks
推荐答案
您可以使用parentApplication
You can use parentApplication
例如...如果我有一个main.mxml来调用组件，我们将其称为child.mxml，那么我可以通过执行以下操作从child内部调用main中的函数:
For example... if i have a main.mxml that calls a component we'll call child.mxml, i can call functions in main from within child by doing the following:
parentApplication.parentsFunctionName(parameters);
