ExtJs 4, what is the right way to Delete control from container and Remove it from the memory?

问题

The question is simple but i can't find a good and clear answer for it.

What is the right way to:

1. Delete control from container
2. Remove it from the memory, in ExtJs 4?

回答1:

Ext.AbstractContainer.remove method can't be far off.

remove( Component/String component, [Boolean autoDestroy]) : Void

Removes a component from this container. Fires the beforeremove event before removing, then fires the remove event after the component has been removed. Parameters

• component : Component/String The component reference or id to remove.

• autoDestroy : Boolean (optional) True to automatically invoke the removed Component's Ext.Component.destroy function. Defaults to the value of this Container's autoDestroy config.
