How to instantiate and apply directives programmat

问题:

I know that in ng2 we have ComponentFactoryResolver that can resolve factories that we can apply to a ViewContainerRef.

But, is there something similar for directives? a way to instantiate them and apply them to the projected content from a component?

回答1:

No, directives can't be added or removed dynamically. They are only applied to HTML statically added to component templates.

What you could do is to enable/disable the directive by passing a parameter (@Input()) to the directive to notify it to do something or not.
