JavaScript JavaScript and the DOM (Retiring) Responding to User Interaction Event Bubbling and Delegation

If the event moves to parent and ancestor elements, doesn't that mean the event handler code would act on all of them?

.

1 Answer

What do you mean by 'act'? However, it is the event that is bubbling not the event listener. The ancestor elements get notified that the event has happened. if there is a listener attached to the ancestor for the same event then it would be executed. If no listener attached to the ancestor for the same event, nothing is going to be executed.
