- Inline error messages
- Creating a master checkbox (that toggles a group of other checkboxes)
- Linked select menus
- Enabling/disabling submit buttons
The chapter also covers regular expressions, with a focus on validation. Because regular expressions are complicated, and there’s already a lot of material in the book, I tried to keep the coverage as accessible as possible, without going into too much high-end stuff. The chapter ends with a good and realistic form validation example that combines most of the above.
- Mobile Development
As always, if there’s not space to put something in the book, I’ll probably end up writing about those subjects here, or as articles elsewhere (so you’ll still get all the important content, you just won’t have to pay for it).
So that’s where things stand. Thanks to everyone for their interest in the book. Now I’m off to write Chapter 11!
