I was surprised to hear that unobtrusive JavaScript is perhaps a “Kool-Aid” phenomenon. This surprised me because I haven’t really thought about inline JavaScript for a while.
It depends how much inline code you write of course; the odd onclick here and there isn’t a big deal. It’s not really a question of being “strict” though, it’s a question of really feeling comfortable with event handling, and how to organise JavaScript effectively.
If you look at my projects, there is some inline JavaScript. Some of this comes from Rails helpers, assorted ugly hacks that I should replace, or the fact I’ve been building these things for a long time. I’m simply describing the way I work now.
