如何删除控制器ExtJS？ [英] How to Delete controller ExtJS?

问题描述

我在我的应用程序中动态创建控制器，如下所示：

I dynamically create controllers in my application like this:

推荐答案

ExtJs目前不支持删除控制器开箱。要清除控制器，请执行以下操作：

ExtJs currently does not support removal of controllers out of the box. To cleanup a controller, do the following:

• 扩展 Ext.app.EventBus 使用方法 uncontrol 取消注册此控制器在EventBus上注册的所有事件侦听器。查看 Ext.app.EventBus＃control 的源代码来得到一个实现。或使用这一个。


• 使用方法 removeController 扩展 Ext.app.Application 从 controllers 集合给定控制器实例。它是一个Ext.util.MixedCollection，检查 Ext.app.Application＃getController 的源代码。然后使用 uncontrol 清除该控制器的所有已注册的侦听器。


• 实施 destroy 方法在您的特定控制器和/或扩展 Ext.app.Controller 。您应该至少调用 clearManagedListeners（），并且可能会销毁此控制器创建的其他对象，如视图或存储，如果适合您的应用程序架构和控制器生命周期。 >
  

• Extend Ext.app.EventBus with a method uncontrol that unregisters all event listeners that this controller registered on the EventBus. Check out the source of Ext.app.EventBus#control to derive an implementation. Or use this one.
• Extend Ext.app.Application with a method removeController that removes a given controller instance from the controllers collection. It's a Ext.util.MixedCollection, check out the source for Ext.app.Application#getController. Then clean up all registered listeners for that controller using uncontrol.
• Implement a destroy method either on your specific controller and/or extend Ext.app.Controller. You should at least call clearManagedListeners() and possibly destroy other objects created by this controller like views or stores, if that suits your application architecture and controller life-cycle.
