JavaScript Event Flow - When would you use it. Real World Example

Question

When would you ever use the Event Flow is an application? What I'm referring to is the third parameter of the AddEventListener function. Can anyone provide a real world example?

Answer 1

There aren't a lot of reasons to use event capturing instead of event bubbling. Furthermore, event capturing isn't supported in IE8.

For more info, this page deals with the differences between bubbling/capturing.

In practice, the only reason that I can think of to use event capturing is to deal with events that don't bubble, namely onfocus and onblur. See also this SO post dealing with onblur
