Before getting to the examples, please work through the HTML Forms tutorial at w3schools. There are many different form elements discussed in the tutorial that you might be able to incorporate into an app. Parts of the tutorial that you should disregard in this context are the parts dealing with form submission. The tutorial discusses submitting form values to a server, where they might be processed by a server-side language like PHP or Ruby. In our context, we’ll be processing the form values on the client device using JavaScript instead. So feel free to skip over the discussion of the Submit button, the action and method attributes, and GET vs. POST.
