JavaScript add events cross-browser function implementation: use attachEvent/addEventListener vs inline events

by

With the 2nd solution, you have to manually call the previous functions, making it hard to remove specific listeners (which, to me, sounds like something you’d rather want than clearing all listeners), while on the first solution, you can only clear them all at the same time, unless you want to emulate the first functionality.

Personally, I always use the first solution, because it has the advantage of not having to worry about clearing possible other event listeners.

The mozilla wiki also lists the advantages that the first solution works on any DOM element, not just HTML elements, and that it allows finer grained control over the phase when the listener gets activated (capturing vs. bubbling) with the third argument.
