For one, you're usually using that class to style something too (a
class="required" can be used for validation and for styling the input
differently to show the user it's a required field), so you use
essentially the same markup to hook in both your presentational layer
and your behavioural layer.

I've rarely used onclick after discovering the unobtrusive way of doing
js, it's easier to maintain and your code looks cleaner.
