Creating, Styling, and Validating Web Forms

This course is all about creating and processing web forms. It starts with using the latest HTML standards to create and provide basic validation for an HTML form. Then it covers styling forms using CSS. This includes showing the validation status of form fields. You'll then learn to write clean, real-time client-side form validation with JavaScript and regular expressions. Finally, you'll learn to validate forms on the server with Node.js, JSON, and Ajax.

  3. Learn to validate forms on the client with JavaScript and regular expressions.
